Insulinoma

Insulinoma is a rare tumor that grows from the insulin-making beta cells in the pancreas. These tumor cells release insulin all the time, even when blood sugar is already low. This extra insulin pushes blood sugar down and causes repeated attacks of hypoglycemia (low blood sugar), especially during fasting or between meals. Most insulinomas are small, usually less than 2 cm, and are benign (non-cancerous), but a small number can be malignant and spread to other organs like the liver or lymph nodes. Insulinoma is the most common functional pancreatic neuroendocrine tumor, but it is still rare, with only about 1–4 cases per million people each year. Cleveland Clinic+2NCBI+2

Insulinoma is a rare tumor that grows from the insulin-making beta cells in the pancreas and makes too much insulin all the time. This extra insulin causes repeated low blood sugar attacks (hypoglycemia), with symptoms like shaking, sweating, confusion, and sometimes loss of consciousness. Most insulinomas are small, single, and benign, but a small number can spread (malignant insulinoma). Surgery to remove the tumor is usually the main and most effective cure, while medicines, diet, and other therapies are used when surgery is not possible, or while the patient is waiting for surgery. PMC+1

Insulinoma belongs to a group called functional pancreatic neuroendocrine tumors, which means the tumor releases hormones that cause symptoms. In advanced or metastatic disease, doctors may use special hormonal injections, targeted tablets, chemotherapy, radioligand therapy, or liver-directed procedures to control both blood sugar and tumor growth. Treatment is usually directed by a multidisciplinary team that includes endocrinologists, surgeons, oncologists, radiologists, and dietitians. PMC+1

Other names for Insulinoma

Insulinoma is known by several other names. Doctors may call it a “pancreatic insulin-secreting neuroendocrine tumor” or “insulin-secreting pancreatic islet cell tumor.” It may also be described as a “functional pancreatic neuroendocrine tumor (pNET) producing insulin.” All these names mean the same thing: a pancreatic tumor that produces too much insulin and causes low blood sugar. NCBI+1

Types of Insulinoma

1. Benign insulinoma
   Most insulinomas are benign, which means they do not invade nearby tissues or spread to distant organs. These tumors usually stay small and limited to the pancreas. Surgery to remove a benign insulinoma often cures the disease and stops the hypoglycemia attacks. Cleveland Clinic+1

2. Malignant insulinoma
   Malignant insulinomas are less common but more serious. They can invade nearby tissues and spread (metastasize), most often to the liver or lymph nodes. Low blood sugar attacks may be more difficult to control, and patients may need medicines or targeted cancer treatments in addition to surgery. Cureus+1

3. Sporadic insulinoma
   Most insulinomas occur “out of the blue,” with no clear family history. These are called sporadic tumors. They are usually single (solitary) tumors in the pancreas. Genetic changes happen only in the tumor cells, not in every cell of the body, so they are not passed on to children. NCBI+1

4. Hereditary (MEN1-related) insulinoma
   Some insulinomas are part of a genetic syndrome called multiple endocrine neoplasia type 1 (MEN1). In MEN1, people can develop tumors in the parathyroid glands, pituitary gland, and pancreas, including insulinoma. These patients may have multiple pancreatic tumors and may develop insulinoma at a younger age. NCBI+1

5. Solitary insulinoma
   A solitary insulinoma means there is only one tumor in the pancreas. This is the most common pattern in people without a genetic syndrome. It is usually easier to locate and remove one tumor compared with multiple tumors. WJGNet

6. Multiple insulinomas
   Some patients, especially those with MEN1, can have many small insulin-secreting tumors scattered through the pancreas. These multiple tumors can make surgery more difficult and may require partial removal of the pancreas instead of simple removal of one nodule. NCBI+1

7. Ectopic insulinoma
   Very rarely, insulinoma can grow outside the pancreas, for example in the duodenum or other nearby tissues. This is called an ectopic insulinoma. Because the tumor is not in the usual place, it may be harder to find on imaging and may delay diagnosis. WJGNet+1

Causes of Insulinoma

1. Sporadic genetic mutations in beta cells
   In most patients, insulinoma develops because of random (sporadic) changes in the DNA of pancreatic beta cells. These mutations cause the cells to grow too much and form a tumor that keeps making insulin even when blood sugar is low. NCBI+1

2. Multiple Endocrine Neoplasia type 1 (MEN1)
   MEN1 is an inherited condition caused by mutations in the MEN1 gene. It increases the risk of tumors in several glands, including insulinoma in the pancreas. People with MEN1 have a much higher chance of developing insulinoma than the general population. NCBI+1

3. Other hereditary pancreatic neuroendocrine tumor syndromes
   Rare genetic syndromes like von Hippel–Lindau disease, neurofibromatosis type 1, and tuberous sclerosis complex can be associated with pancreatic neuroendocrine tumors. In a small number of cases, these tumors secrete insulin and behave like insulinomas. ScienceDirect+1

4. Altered menin protein function
   In both familial and some sporadic insulinomas, the MEN1 gene, which encodes the protein menin, may be damaged. Menin normally helps control cell growth. When it does not work properly, pancreatic endocrine cells can multiply and form tumors that secrete insulin. NCBI+1

5. Abnormal mTOR signaling pathway
   Some insulinomas show changes in pathways that control cell growth and survival, such as the mTOR pathway. Over-activation of these pathways can push beta cells to grow uncontrollably and resist natural cell death, promoting tumor formation. Endotext+1

6. Chromosomal and epigenetic changes
   Genome and epigenome studies have found chromosomal losses, gains, and DNA methylation changes in pancreatic neuroendocrine tumors. These changes can switch on growth-promoting genes or switch off tumor-suppressor genes, favoring the development of insulinoma. Endotext+1

7. Family history of pancreatic neuroendocrine tumors
   A strong family history of pancreatic endocrine tumors increases the likelihood of hereditary syndromes or shared genetic susceptibility. In such families, a person may develop insulinoma at a younger age or have multiple tumors. NCBI+1

8. Chronic hormone and growth factor stimulation
   Long-term stimulation of beta cells by high levels of growth factors or hormones may encourage extra cell division. Over time, this repeated stimulation can increase the chance that a beta cell acquires mutations and turns into an insulin-secreting tumor. Endotext+1

9. Defects in DNA repair mechanisms
   When DNA repair systems do not work well, damaged DNA in beta cells may not be fixed correctly. This allows mutations to build up. In some patients with insulinoma and other tumors, defects in cell-cycle control and repair genes have been reported. Endotext+1

10. Immune system failure to remove abnormal cells
    The immune system usually recognizes and destroys abnormal cells. If immune surveillance is weak or altered, early tumor cells in the pancreas may survive and expand, eventually forming an insulinoma. Endotext

11. Age (middle adulthood)
    Insulinoma most often appears in adults between 40 and 60 years old, although it can occur at any age. Age itself does not cause the tumor, but with more time, there is a higher chance for DNA damage and tumor growth. NCBI+1

12. Female sex (slight predominance)
    Several series report a slight female predominance in insulinoma cases. The exact reason is unclear, but it may be related to hormonal influences or genetic factors. It is better seen as an association rather than a direct cause. NCBI+1

13. Long-standing insulin resistance and beta-cell stress
    In theory, long-term insulin resistance can make beta cells work harder and proliferate. In some people, this chronic stress might increase the chance of abnormal clones that could become an insulin-secreting tumor, although strong direct evidence is limited. Endotext+1

14. Exposure to environmental carcinogens
    Like other tumors, insulinoma may be influenced by exposure to DNA-damaging agents such as tobacco smoke or certain chemicals. These agents can cause mutations in pancreatic cells, but this link is not as well studied as in lung or colon cancer. ScienceDirect

15. Prior abdominal radiation
    Radiation to the abdominal area for other cancers can increase the risk of different tumors later in life. Although insulinoma specifically is rare, radiation can damage DNA in pancreatic cells and might contribute in some cases. ScienceDirect+1

16. Chronic pancreatic disease
    Conditions like chronic pancreatitis change the pancreatic environment through inflammation and fibrosis. This may alter normal cell growth signals and, rarely, may be associated with neuroendocrine tumors, including insulinoma. ScienceDirect

17. Other endocrine tumors (MEN1 context)
    In MEN1, the presence of parathyroid and pituitary tumors shows that the whole endocrine system is prone to tumor growth. This same tendency makes insulinoma more likely, as all endocrine tissues share the underlying MEN1 gene defect. SpringerLink+1

18. Epigenetic silencing of tumor-suppressor genes
    Even without obvious gene mutations, epigenetic changes can “turn off” tumor-suppressor genes. In pancreatic neuroendocrine tumors, abnormal methylation patterns have been found and may play a role in insulinoma development. Endotext+1

19. Altered angiogenesis (blood vessel growth)
    Insulinomas, like other neuroendocrine tumors, are often very rich in blood vessels. Changes in factors that control blood vessel growth, such as VEGF, may promote tumor survival and expansion in the pancreas. Endotext+1

20. Unknown or idiopathic causes
    In many patients, no clear cause is identified. There is no family syndrome, no obvious risk factor, and no known exposure. For these people, insulinoma is considered idiopathic, meaning it arises from unknown or complex interactions of genetic and environmental factors. NCBI+1

Symptoms of Insulinoma

1. Fasting hypoglycemia attacks
   The most important symptom is repeated episodes of low blood sugar, especially after several hours without food or during the night. Patients may wake up feeling very unwell, shaky, or confused, and get better quickly after eating or drinking something sweet. NCBI+1

2. Sweating
   During hypoglycemia, the body releases stress hormones like adrenaline. This can cause cold, clammy sweating even in a cool room. The sweating often comes suddenly and may be one of the earliest warning signs that blood sugar is falling. Cleveland Clinic+1

3. Shakiness and tremor
   Low blood sugar activates the sympathetic nervous system and can lead to fine shaking of the hands or internal tremor. Patients may feel nervous, jittery, or unable to hold objects steadily during an episode. NCBI+1

4. Fast heartbeat (palpitations)
   Adrenaline release also speeds up the heart. People may feel pounding in the chest or notice their heart racing. This can be frightening and may be mistaken for anxiety or panic attacks. NCBI+1

5. Extreme hunger
   The brain senses that glucose is low and sends strong hunger signals. Patients often feel an urgent need to eat, especially for sugary foods, during attacks. Eating usually brings quick relief, which is part of Whipple’s triad. Cleveland Clinic+1

6. Weakness and fatigue
   Muscles and the brain both need glucose for energy. When levels drop, patients feel very weak, tired, and may have trouble doing normal tasks. This fatigue usually improves after food or glucose. NCBI+1

7. Confusion and poor concentration
   Neuroglycopenic symptoms occur when the brain does not get enough glucose. Patients may become confused, slow to respond, or unable to focus on simple tasks, and may not remember the episode later. NCBI+2Istanbul Medical Journal+2

8. Behavior and personality changes
   Some people with insulinoma show strange behavior during hypoglycemia, such as irritability, aggression, or acting drunk. Family members may notice these changes more than the patient, who may be unaware during the episode. NCBI+1

9. Blurred or double vision
   Because the brain and eye pathways lack glucose, vision can become blurred, dim, or double during attacks. These visual changes can make walking or driving unsafe until blood sugar is corrected. NCBI+1

10. Headache
    Hypoglycemia can trigger headaches, sometimes with dizziness or lightheadedness. Headaches often occur after a period of fasting and may improve when the person eats or drinks something containing sugar. NCBI+1

11. Difficulty speaking or slurred speech
    When the brain is starved of glucose, speech centers may not work properly. Patients can have slurred speech, trouble finding words, or difficulty organizing sentences, which can resemble a stroke. NCBI+2Istanbul Medical Journal+2

12. Seizures or convulsions
    Severe hypoglycemia can cause electrical disturbance in the brain and lead to seizures. People may be misdiagnosed with epilepsy until low blood sugar from insulinoma is recognized as the real cause. NCBI+2ScienceDirect+2

13. Loss of consciousness or fainting
    If hypoglycemia is deep or prolonged, the person can become unresponsive or collapse. This is a medical emergency and requires rapid glucose treatment and later investigation to find the cause, including possible insulinoma. NCBI+2Istanbul Medical Journal+2

14. Unexplained weight gain
    Many patients gain weight because they eat frequently to relieve low blood sugar episodes. They may crave high-calorie foods and snacks to stop symptoms, leading to gradual weight gain over months or years. Cleveland Clinic+1

15. Night-time or early-morning episodes
    Hypoglycemia often happens at night or before breakfast, when the person has not eaten for several hours. Patients may wake with headaches, confusion, or sweating, or find symptoms worse first thing in the morning. NCBI+2WJGNet+2

Diagnostic Tests for Insulinoma

Physical Examination Tests

1. Detailed medical history and general physical examination
   The doctor asks about timing of symptoms, relation to meals, relief with food, past illnesses, and family history, while checking weight, blood pressure, pulse, and general appearance. This helps suspect insulinoma when recurrent fasting hypoglycemia fits Whipple’s triad. NCBI+2Dove Medical Press+2

2. Neurological examination during or after episodes
   The clinician checks mental state, memory, coordination, reflexes, and eye movements. Abnormal findings during hypoglycemia (confusion, poor coordination, seizures) support neuroglycopenia and encourage further testing for causes like insulinoma. NCBI+1

3. Autonomic signs check (pulse, blood pressure, sweating)
   During attacks, the doctor may observe sweating, tremor, rapid heartbeat, and blood pressure changes. These autonomic signs show the body is reacting to low glucose and help confirm that symptoms are consistent with hypoglycemia. NCBI+1

Manual Tests (Bedside and Provocation)

4. Bedside capillary blood glucose test (finger-prick)
   A small drop of blood from the fingertip is tested with a glucometer at the bedside when symptoms occur. A low reading supports hypoglycemia and prompts more precise laboratory tests to document plasma glucose and insulin levels. Cleveland Clinic+1

5. Bedside Whipple’s triad assessment
   The clinician documents three things at the same time: symptoms of hypoglycemia, low glucose level, and relief of symptoms after giving glucose or food. When all three are present, Whipple’s triad is positive and strongly suggests a hypoglycemia disorder such as insulinoma. Dove Medical Press+2njmonline.nl+2

6. Short supervised fasting observation in clinic
   In some cases, a brief fast under supervision is done, with frequent checks of bedside glucose and symptoms. If glucose falls and symptoms appear quickly, the team may proceed to a formal extended fasting test in a hospital setting. njmonline.nl+1

Laboratory and Pathological Tests

7. Venous plasma glucose level during symptoms
   A blood sample taken from a vein during an episode measures true plasma glucose. A value below about 3.0 mmol/L (or under 55 mg/dL), together with symptoms, is a key part of confirming clinically important hypoglycemia. PubMed+2labmed.org.uk+2

8. Fasting serum insulin concentration
   Insulin should normally be low when glucose is low. In insulinoma, insulin is inappropriately high or in the normal range while glucose is low. Measuring insulin during hypoglycemia is essential for diagnosing endogenous hyperinsulinemic hypoglycemia. PubMed+2ARUP Consult+2

9. C-peptide level
   C-peptide is released in equal amounts with natural insulin from the pancreas. High C-peptide and insulin together during hypoglycemia suggests the body is making too much insulin, as in insulinoma, and helps distinguish this from injected (exogenous) insulin, which lowers C-peptide. PubMed+2njmonline.nl+2

10. Proinsulin measurement
    Proinsulin is a precursor of insulin. Many insulinomas release large amounts of proinsulin. Elevated proinsulin levels during hypoglycemia are a strong marker of insulinoma and help separate it from other causes of low blood sugar. NCBI+2ARUP Consult+2

11. Beta-hydroxybutyrate level
    During normal fasting, ketone bodies like beta-hydroxybutyrate rise as the body burns fat. In insulinoma, excess insulin suppresses ketone production, so beta-hydroxybutyrate stays low even when glucose is low. Measuring this helps confirm inappropriate insulin activity. PubMed+2ARUP Consult+2

12. Serum or urine sulfonylurea / hypoglycemic drug screen
    This test looks for diabetes medicines such as sulfonylureas in the blood or urine. A positive result suggests factitious (drug-induced) hypoglycemia instead of insulinoma. A negative test supports endogenous overproduction of insulin. PubMed+2ARUP Consult+2

13. 72-hour supervised fasting test with serial labs
    The 72-hour fast is the gold standard test. The patient is admitted to hospital and fasts under close observation. Blood samples are taken regularly to measure glucose, insulin, C-peptide, proinsulin, beta-hydroxybutyrate, and drug levels. Reproduction of Whipple’s triad with inappropriate insulin confirms insulinoma in most cases. njmonline.nl+2ARUP Consult+2

14. Chromogranin A and other neuroendocrine tumor markers
    Chromogranin A is a protein often raised in neuroendocrine tumors, including some insulinomas. While not specific, elevated levels can support the presence of a neuroendocrine tumor and help monitor disease burden or response to treatment. Endotext+1

Electrodiagnostic Tests

15. Electrocardiogram (ECG)
    An ECG records electrical activity of the heart. During hypoglycemia, it may show fast heart rate or rhythm changes. Although not specific for insulinoma, ECG helps assess how low blood sugar episodes affect the heart and rule out primary heart disease. PubMed+1

16. Electroencephalogram (EEG)
    EEG measures brain electrical activity. In patients with seizure-like episodes due to hypoglycemia, EEG may show changes during attacks but can be normal between them. EEG is useful to distinguish true epilepsy from hypoglycemic seizures caused by insulinoma. ScienceDirect+1

Imaging Tests

17. Contrast-enhanced pancreatic CT scan
    A CT scan with contrast dye can show small enhancing nodules in the pancreas that represent insulinoma. CT also checks for spread to liver or lymph nodes. Modern multi-slice CT has improved detection, but very small tumors can still be missed. MDPI+1

18. Pancreatic MRI
    MRI uses magnetic fields instead of X-rays and can provide detailed images of soft tissues. Insulinomas often appear as well-defined lesions with strong enhancement on certain MRI sequences. MRI is particularly helpful when CT is inconclusive or when radiation exposure is a concern. MDPI+1

19. Endoscopic ultrasound (EUS) of the pancreas
    In EUS, an ultrasound probe on the tip of an endoscope is passed through the stomach and duodenum to scan the pancreas from close range. It is very sensitive for small insulinomas and allows fine-needle aspiration (FNA) biopsy for cytology if needed. MDPI+1

20. Somatostatin receptor imaging (Ga-68 DOTATATE PET/CT or Octreoscan)
    Many neuroendocrine tumors, including insulinomas, express somatostatin receptors. Special radioactive tracers that bind these receptors are used in PET/CT or nuclear scans to highlight tumors and metastases throughout the body, guiding surgery and treatment planning. ScienceDirect+2rasayely-journals.com+2

Non-Pharmacological Treatments

1. Frequent Small Meals
   Eating small meals or snacks every 2–3 hours helps keep blood sugar more stable and reduces big falls in glucose that trigger symptoms. Meals combine slow carbohydrates (whole grains), lean protein, and some healthy fat so that sugar enters the blood slowly. This method does not treat the tumor, but it can lessen hypoglycemia episodes and improve daily functioning while other treatments are being planned. MSD Manuals+1

2. Bedtime and Night-Time Snacks
   A carbohydrate-rich bedtime snack, such as oatmeal, whole-grain bread with nut butter, or yogurt with fruit, can reduce night-time and early-morning hypoglycemia. The goal is to provide a slow and steady release of glucose during sleep when long fasting periods happen. This strategy is simple, low cost, and often combined with medicines to smooth blood sugar swings in insulinoma. PMC+1

3. Raw or Modified Cornstarch Therapy
   Uncooked or specially processed cornstarch is digested slowly and releases glucose over many hours. In case reports and small studies, raw-cornstarch–based diets reduced insulinoma-related hypoglycemia and improved quality of life by providing a constant background source of sugar. It is usually mixed into drinks or soft foods at scheduled times and must be supervised by a dietitian or doctor. ResearchGate+2ECronicon+2

4. Low Glycemic Index Diet
   A low-glycemic index diet favors foods that raise blood sugar slowly, such as whole grains, legumes, vegetables, and some fruits. By avoiding highly refined sugars and white flour products, the post-meal glucose peak is smaller, and reactive falls in blood sugar may be less severe. This approach can be combined with other therapies and tailored to patient preferences and cultures. MSD Manuals+1

5. Protein With Every Meal
   Adding lean protein (fish, eggs, yogurt, pulses, tofu, or lean meat) to each meal slows gastric emptying and carbohydrate absorption. Protein also helps maintain muscle mass in patients who may gain fat weight due to frequent eating to avoid hypoglycemia. This strategy is a basic diet rule in many neuroendocrine tumor nutrition leaflets. Scribd+1

6. Limiting Simple Sugars
   Very sugary drinks or sweets can cause a fast rise and then a sharp fall in blood sugar, which may worsen hypoglycemia in insulinoma. Patients are usually advised to save fast sugars (like glucose tablets or juice) only for emergency treatment of an active hypoglycemic episode, not for routine snacks. This helps avoid repeated “sugar rollercoasters.” MSD Manuals+1

7. Dietitian-Guided Meal Planning
   Working with a dietitian experienced in neuroendocrine tumors allows a personalized eating plan that respects local foods, religious patterns, and other health problems (like obesity or kidney disease). The dietitian can adjust carbohydrate amount, timing, and cornstarch use and monitor weight, vitamins, and bowel habits. This team care is part of modern insulinoma management. PMC+1

8. Education and Hypoglycemia Awareness Training
   Patients and families learn how to recognize early warning signs of hypoglycemia, how to check capillary blood glucose, and how to treat low sugar quickly with oral glucose or glucagon if prescribed. Education reduces fear, emergency admissions, and driving accidents, and helps patients share information with school or workplace staff. PMC+1

9. Medical Alert Identification
   Wearing a medical alert bracelet or carrying a card that states “Insulinoma – risk of hypoglycemia” helps first responders provide correct care in emergencies. It also reminds healthcare workers to check blood glucose quickly if the patient is confused, drowsy, or has a seizure. This simple tool improves safety in daily life. PMC+1

10. Supervised Physical Activity
    Light to moderate exercise improves overall health but must be planned carefully, because activity can lower blood glucose. Patients are advised to eat a snack before and sometimes during longer activities and to carry fast glucose sources. A physiotherapist or doctor can design an activity plan that avoids intense, prolonged fasting exercise until blood sugar is better controlled. PMC+1

11. Avoiding Prolonged Fasting
    Long gaps between meals, strict weight-loss diets, or religious fasts can be very dangerous in insulinoma, because insulin secretion continues even without food. Patients are usually advised to avoid fasting and to discuss any religious or cultural fasting plans with their healthcare team to find safe alternatives. PMC+1

12. Emergency Action Plan at Home and Work
    A written plan explains what family, friends, teachers, or colleagues should do if hypoglycemia happens, including giving oral glucose if the patient is awake or calling emergency services if they are unconscious. Some patients also keep glucagon injections or nasal glucagon, if prescribed, at home or school. FDA Access Data+1

13. Psychological Support and Counseling
    Living with unpredictable low blood sugar can cause anxiety, fear of leaving home, and low mood. Counseling or cognitive behavioral therapy can help patients regain confidence and learn coping strategies. Mental health support is especially important in patients with chronic or metastatic insulinoma. PMC+1

14. Driving and Safety Restrictions
    Doctors may advise not to drive or operate heavy machinery until hypoglycemia is well controlled because sudden low sugar can cause accidents. Many countries have specific legal rules about driving with recurrent hypoglycemia. Following these safety rules protects both the patient and the public. PMC+1

15. Inpatient Glucose Stabilization
    In severe or refractory cases, patients may be admitted to hospital for continuous intravenous glucose and monitoring while the team optimizes medications or prepares surgery. This controlled setting allows safe correction of extreme hypoglycemia and prevents brain injury. PMC+1

16. Continuous Glucose Monitoring (CGM)
    CGM devices use a tiny sensor under the skin to record glucose levels every few minutes and send alerts when they fall. Although originally designed for diabetes, CGM can help detect silent nighttime hypoglycemia in insulinoma and assist doctors in evaluating treatment response. PMC+1

17. Placement of Central Venous Access for IV Therapies
    In some advanced cases, a central venous catheter or port is placed to deliver long-term intravenous glucose, chemotherapy, or targeted therapy more safely and with less discomfort than repeated peripheral cannulas. This is usually considered when long-term systemic treatment is planned. Ageb+1

18. Liver-Directed Local Therapies (Non-Drug Component)
    For metastatic insulinoma with many liver lesions, procedures such as radiofrequency ablation or embolization reduce tumor bulk and hormone secretion. These procedures are done by interventional radiologists and are often combined with systemic drugs but are themselves “physical” therapies aimed at shrinking tumor tissue. MDPI+1

19. Peptide Receptor Radionuclide Therapy (PRRT) Care Pathway
    PRRT using lutetium Lu-177 dotatate is given in cycles with specific hydration, anti-nausea medicines, and amino acid infusions to protect kidneys. Although PRRT includes a radiolabeled drug, the full pathway also has strong non-drug elements: patient selection, nuclear medicine imaging, and radiation-safety counseling. PMC+2FDA Access Data+2

20. Long-Term Follow-Up and Screening for MEN1
    Because some insulinomas occur as part of MEN1 syndrome, family and long-term endocrine follow-up help detect new tumors early. Regular blood tests, imaging, and clinical review lower the risk of sudden severe hypoglycemia and allow timely surgery or systemic therapy. PMC+1

Drug Treatments

Important: Doses below are typical adult doses from labels or studies. They are not personal advice. Never start, stop, or change any medicine without your specialist.

1. Diazoxide (PROGLYCEM)
   Diazoxide is an oral medicine that reduces insulin release from pancreatic beta cells and is a classic first-line drug for hypoglycemia caused by inoperable insulinoma. A common adult dose is about 3–8 mg/kg/day in divided doses, adjusted by doctors. It raises blood sugar but can cause fluid retention, swelling, nausea, excess hair growth, and sometimes heart failure, so monitoring of blood pressure, kidneys, and electrolytes is essential. FDA Access Data+1

2. Octreotide Short-Acting Injection (Sandostatin)
   Octreotide is a synthetic somatostatin analog that blocks insulin and other hormone release by acting on somatostatin receptors on tumor cells. It is given subcutaneously, often 50–100 micrograms two or three times daily to test tolerance and effect on hypoglycemia before moving to long-acting forms. Side effects include abdominal pain, diarrhea, gallstones, and changes in blood sugar. Medscape+2FDA Access Data+2

3. Octreotide Long-Acting Release (LAR)
   Long-acting octreotide is injected deep into muscle every 4 weeks (commonly 20–30 mg, adjusted by response) to control hormone secretion and sometimes slow tumor growth in neuroendocrine tumors. In insulinoma, about half of patients respond with better hypoglycemia control. Side effects are similar to short-acting octreotide but more prolonged, including GI upset, gallbladder stones, and potential worsening of glucose in some cases. Medscape+2PMC+2

4. Lanreotide Depot (Somatuline Depot)
   Lanreotide is another long-acting somatostatin analog given as a deep subcutaneous injection, usually 120 mg every 4 weeks. FDA labeling shows it improves progression-free survival in patients with gastroenteropancreatic neuroendocrine tumors, including those of pancreatic origin, and may help control hormone-related symptoms. Common side effects are diarrhea, abdominal pain, gallstones, and injection-site reactions. FDA Access Data+2somatulinedepot.com+2

5. Everolimus (AFINITOR)
   Everolimus is an oral targeted therapy that blocks mTOR, a key pathway driving tumor cell growth and blood-vessel formation. FDA labeling approves everolimus 10 mg once daily for progressive pancreatic neuroendocrine tumors that cannot be removed by surgery. Studies show longer progression-free survival and good control of hypoglycemia in malignant insulinoma, but side effects include mouth ulcers, rash, infections, anemia, and high blood sugar. jnm.snmjournals.org+4FDA Access Data+4FDA Access Data+4

6. Sunitinib (SUTENT)
   Sunitinib is a multi-target tyrosine kinase inhibitor that blocks VEGF and PDGF receptors and slows tumor blood-vessel growth. FDA labels approve sunitinib 37.5 mg orally once daily for progressive pancreatic neuroendocrine tumors that are unresectable or metastatic. Clinical trials show better progression-free survival but side effects include fatigue, diarrhea, high blood pressure, hand–foot skin reaction, low blood counts, and thyroid problems. Dove Medical Press+3FDA Access Data+3FDA Access Data+3

7. Cabozantinib (CABOMETYX)
   Cabozantinib is another tyrosine kinase inhibitor that targets MET, VEGFR, and other receptors. Recent FDA labeling includes its use for unresectable, locally advanced, or metastatic pancreatic neuroendocrine tumors after prior therapy, based on the CABINET trial. A common dose is 60 mg orally once daily, adjusted for tolerance. Side effects include diarrhea, fatigue, hand–foot syndrome, hypertension, and risk of bleeding or clotting. FDA Access Data+2Eur.nl+2

8. Lutetium Lu-177 Dotatate (LUTATHERA)
   Lutathera is a radiolabeled somatostatin analog used in peptide receptor radionuclide therapy. It binds to somatostatin receptors on neuroendocrine tumor cells and delivers targeted radiation. FDA labeling approves it for somatostatin receptor-positive GEP-NETs in adults and children ≥12 years, given as 7.4 GBq (200 mCi) IV every 8 weeks for 4 doses with amino acid infusions. Main side effects include nausea, vomiting, bone-marrow suppression, and potential kidney and liver toxicity. ClinPGx+3FDA Access Data+3ESMO+3

9. Glucagon Injection or Autoinjector
   Glucagon is a natural hormone that quickly raises blood sugar by releasing stored glucose from the liver. Injectable or nasal glucagon products are FDA-approved for severe hypoglycemia and can be used in insulinoma emergencies when the patient cannot take oral sugar. Side effects are usually nausea and vomiting. Family members are taught how and when to use the device. FDA Access Data+1

10. Intravenous Dextrose (Glucose)
    Concentrated intravenous dextrose (for example 10–50% solutions) is the fastest way to correct severe hypoglycemia in hospital. It is not a long-term treatment for insulinoma but a vital rescue therapy used in emergency rooms or intensive care while other measures start. Risks include vein irritation and rebound hypoglycemia if the underlying cause is not controlled. PMC+1

11. Capecitabine (Part of CAPTEM)
    Capecitabine is an oral prodrug of 5-fluorouracil that interferes with DNA synthesis in rapidly dividing cells. In pancreatic neuroendocrine tumors, it is often combined with temozolomide (CAPTEM) to shrink tumors and control hormone secretion when other options fail. Side effects include hand–foot syndrome, diarrhea, mouth sores, and low blood counts, so patients need close oncology follow-up. Eur.nl+2ResearchGate+2

12. Temozolomide (Part of CAPTEM)
    Temozolomide is an oral alkylating agent that damages tumor DNA and works especially well in combination with capecitabine in neuroendocrine tumors. Typical regimens use cycles of temozolomide for 5 days every 28 days, with doses adjusted to body size and blood counts. Side effects include fatigue, nausea, bone-marrow suppression, and rare risk of secondary blood cancers. Eur.nl+1

13. Streptozocin-Based Chemotherapy
    Streptozocin is an older IV chemotherapy that has specific activity against pancreatic islet-cell tumors and has been used for metastatic insulinoma. It is often combined with other agents such as 5-fluorouracil. Side effects can be significant, including nausea, vomiting, kidney toxicity, and bone-marrow suppression, so it is usually reserved for advanced disease in specialist centers. Dove Medical Press+1

14. 5-Fluorouracil (5-FU)
    5-FU is a cytotoxic drug that blocks DNA synthesis and is part of some regimens for pancreatic neuroendocrine tumors. It can be given as a slow infusion or oral prodrug combinations and may offer modest tumor control when targeted therapies and somatostatin analogs are not enough. Side effects include mucositis, diarrhea, low blood counts, and hand–foot syndrome. ResearchGate+1

15. Oxaliplatin
    Oxaliplatin is a platinum-based chemotherapy that damages tumor DNA and is sometimes used with 5-FU and capecitabine in neuroendocrine tumor protocols. It may help shrink bulky or aggressive disease but carries risks of neuropathy (numbness, tingling), low blood counts, and allergic reactions, so careful balancing of risks and benefits is needed. ResearchGate+1

16. Pasireotide
    Pasireotide is a newer somatostatin analog with broader receptor binding, studied for difficult neuroendocrine tumors and Cushing’s disease. In insulinoma, small series suggest it may help control hypoglycemia when octreotide is not effective, but it can significantly raise blood sugar and is not yet a standard first-line choice. MDPI+1

17. Glucocorticoids (e.g., Prednisone)
    Glucocorticoids increase insulin resistance and promote gluconeogenesis, which can help raise blood sugar in some tumor-related hypoglycemia settings. In insulinoma, they may be used short-term when other options fail or while waiting for definitive therapy. Risks include weight gain, mood changes, infection risk, osteoporosis, and worsening diabetes, so they must be used carefully. endocrinologydiabetes.org+1

18. Lanreotide or Octreotide Plus PRRT Combination
    Somatostatin analogs are often continued during PRRT to stabilize hormone secretion and maintain receptor expression. This “drug plus radioligand” approach can improve symptom control, including hypoglycemia, and is now a common strategy in advanced neuroendocrine tumors. Side effects reflect both SSA and PRRT toxicities, especially GI upset and bone-marrow suppression. PMC+2Eur.nl+2

19. Everolimus After PRRT
    In treatment sequences for advanced functional pancreatic neuroendocrine tumors, guidelines suggest everolimus after PRRT to further control tumor growth. This strategy recognizes that each line of therapy offers different benefits and side effects, and the order is chosen based on tumor grade, growth rate, and patient health. Eur.nl+1

20. Cabozantinib After PRRT or Targeted Therapy
    Cabozantinib is increasingly used as a later-line targeted option in pancreatic NETs when disease progresses after SSAs, PRRT, everolimus, or sunitinib. It offers additional anti-angiogenic and anti-tumor effects but requires monitoring for hypertension, diarrhea, hand–foot syndrome, and blood-clot risk. This drug broadens options for patients with complex, metastatic insulinoma. FDA Access Data+2Eur.nl+2

Dietary Molecular Supplements

These supplements do not cure insulinoma. They may support nutrition or metabolic health and must be discussed with a doctor to avoid interactions.

1. Soluble Fiber (e.g., Psyllium)
   Soluble fiber slows stomach emptying and carbohydrate absorption, which can help soften rapid swings in blood sugar after meals. A typical adult dose is 5–10 g with water before meals, adjusted to bowel tolerance. It may also improve cholesterol and gut health. Gas or bloating can occur if the dose is increased too fast, so starting low and going slow is best. Scribd+1

2. Whey or Plant Protein Supplements
   Protein shakes based on whey or soy can support adequate protein intake when patients are eating many small meals and risk excess calories from fat and sugar. Around 20–30 g of protein powder once or twice daily may be used under dietitian guidance. Protein slows glucose absorption and helps protect muscle mass, but renal function must be checked in kidney disease. Scribd+1

3. Vitamin D
   Vitamin D supports bone health, muscle function, and immune regulation. Deficiency is common in chronic illness and in patients with limited sunlight exposure. Typical replacement doses range from 600–2000 IU daily, individualized after blood testing. Correcting deficiency may reduce bone loss in patients receiving steroids, targeted therapies, or who are less active due to hypoglycemia. MDPI+1

4. Omega-3 Fatty Acids (Fish Oil or Algal Oil)
   Omega-3 fats have anti-inflammatory and cardiovascular benefits. Doses of about 1 g/day of EPA/DHA are commonly used in heart-health studies. In insulinoma, omega-3s may support general health and may help manage triglycerides in patients receiving certain targeted therapies, though they do not affect the tumor itself. Fish-oil capsules can cause fishy aftertaste and should be used with caution in bleeding disorders. MDPI+1

5. Magnesium
   Many chemotherapy and targeted therapy regimens can lower magnesium levels, leading to cramps or arrhythmias. Oral magnesium (for example 200–400 mg elemental magnesium daily) can restore levels when deficiency is documented. Too much magnesium can cause diarrhea and is unsafe in severe kidney disease, so levels should be monitored by a doctor. MDPI+1

6. Vitamin B-Complex
   B vitamins support energy metabolism and nervous system function. They may help correct nutritional gaps in patients eating very restricted diets to avoid hypoglycemia or receiving chemotherapy. Typical B-complex supplements provide B1, B2, B6, B12, niacin, and folate in low daily doses. Excessive doses can cause nerve problems (B6) or interact with certain drugs, so medical advice is important. MDPI+1

7. Probiotics
   Probiotics provide beneficial bacteria that may help manage treatment-related diarrhea from somatostatin analogs, chemotherapy, or targeted therapies. Common regimens use several billion colony-forming units daily from Lactobacillus or Bifidobacterium strains. Evidence supports benefits in some GI conditions, but not specifically in insulinoma, so they are considered supportive care only. MDPI+1

8. Medium-Chain Triglyceride (MCT) Oil
   MCT oil is absorbed quickly and used as an energy source without needing bile salts. Small doses (5–10 mL with meals) can provide extra calories without heavy fat load and may be helpful in patients with pancreatic insufficiency or weight loss after surgery. Overuse can cause GI upset, so dietitian supervision is advised. MDPI+1

9. Chromium (With Caution)
   Chromium has been studied in type 2 diabetes for its role in insulin sensitivity, but evidence is mixed. In insulinoma, the main problem is excessive insulin, so chromium is not used to improve insulin action. If a patient already takes chromium for other reasons, doctors will usually review it carefully and may stop it. This example shows why all supplements must be discussed with a specialist. MDPI+1

10. Alpha-Lipoic Acid (ALA)
    ALA is an antioxidant sometimes used for diabetic neuropathy. It has no proven role in treating insulinoma but may be considered for nerve symptoms caused by long-standing hypoglycemia or chemotherapy. Typical doses in studies are 300–600 mg/day. Because ALA can influence blood sugar, it must be used cautiously and only under medical supervision. MDPI+1

Regenerative and Immune-Modulating Therapies

There are no FDA-approved stem cell or regenerative drugs that cure insulinoma or regrow healthy pancreas tissue. However, several advanced therapies affect tumor cells or the immune system and are being used or studied in pancreatic neuroendocrine tumors. erc.bioscientifica.com+1

1. Peptide Receptor Radionuclide Therapy (PRRT) with Lutetium Lu-177 Dotatate
   PRRT delivers targeted radiation to somatostatin receptor-positive tumor cells, causing DNA damage and gradual tumor shrinkage while sparing most normal tissue. It can be seen as a “biologic” precision therapy rather than classic chemotherapy. In metastatic insulinoma, PRRT has achieved good symptom control and longer disease stability in many case series. Eur.nl+3PMC+3FDA Access Data+3

2. Everolimus as a Tumor-Microenvironment Modulator
   Everolimus not only slows tumor cell growth via mTOR but also affects immune cells and blood-vessel growth within the tumor microenvironment. This can make the environment less friendly for tumor survival and may enhance effects of other therapies in sequences after PRRT. It is taken orally long-term, with careful monitoring for infections and metabolic side effects. ASCO Journals+3FDA Access Data+3Dove Medical Press+3

3. Tyrosine Kinase Inhibitors (Sunitinib and Cabozantinib)
   TKIs reduce tumor blood-vessel formation and may also influence immune-cell behavior within tumors. While not “stem cell drugs,” they are key targeted agents for advanced pancreatic NETs and sometimes metastatic insulinoma. They are oral medicines taken daily and can be sequenced after SSAs or PRRT as part of long-term control strategies. ResearchGate+4FDA Access Data+4FDA Access Data+4

4. Combination Approaches (PRRT plus Chemotherapy or Targeted Agents)
   Research is exploring combinations such as PRRT plus CAPTEM or PRRT plus targeted agents to deepen tumor responses. These strategies aim to hit tumor cells through DNA damage, anti-angiogenic effects, and signaling pathway blockade at the same time. They remain experimental and are usually used in clinical trials or specialist centers. PMC+2Eur.nl+2

5. Immune Checkpoint Inhibitors (e.g., Pembrolizumab in Trials)
   Checkpoint inhibitors such as pembrolizumab unleash T-cells to attack cancer cells. Trials are investigating them in combination with lanreotide for advanced GEP-NETs, although data in insulinoma are still very limited. These drugs can cause strong immune-related side effects affecting many organs and are currently reserved for research or highly selected cases. MDPI+1

6. Future Stem Cell or Islet-Cell Approaches
   Experimental concepts include replacing or editing abnormal islet cells and correcting genetic changes in inherited syndromes such as MEN1. At present, these ideas are at laboratory or very early clinical-research stages and are not available as standard treatment. Patients should be very cautious about any clinic that claims to offer stem cell cures for insulinoma outside approved trials. erc.bioscientifica.com+1

Surgical Treatments

1. Enucleation of the Tumor
   For small, solitary, benign insulinomas on the surface of the pancreas, surgeons can “shell out” the tumor while leaving most pancreatic tissue intact. This operation often cures the disease and preserves pancreatic function. It is usually done with open or minimally invasive techniques, depending on tumor location and surgical expertise. PMC+1

2. Distal Pancreatectomy
   If the tumor lies in the body or tail of the pancreas or if there are multiple nearby lesions, surgeons may remove the distal part of the pancreas, sometimes along with the spleen. This provides a wide margin around the tumor and reduces the chance of recurrence but may increase the risk of diabetes or pancreatic enzyme insufficiency. PMC+1

3. Pancreaticoduodenectomy (Whipple Procedure)
   Tumors in the head of the pancreas may need a Whipple procedure, which removes the pancreatic head, part of the small intestine, bile duct, and gallbladder, followed by reconstruction. This is major surgery done in high-volume centers and offers the best chance of cure for localized disease in this region but has significant risks and a long recovery period. PMC+1

4. Minimally Invasive (Laparoscopic or Robotic) Surgery
   Many small, well-located insulinomas can be removed laparoscopically or robotically, using several small incisions instead of one large cut. These techniques can reduce pain and hospital stay, but they require experienced surgeons and careful pre-operative localization (with imaging and sometimes intra-operative ultrasound). PMC+1

5. Liver Metastasectomy and Ablation
   In metastatic insulinoma with limited liver spread, surgeons may remove liver metastases or destroy them with ablation. Reducing tumor burden can significantly improve hypoglycemia and may prolong survival when combined with systemic therapies like SSAs, everolimus, or PRRT. OUP Academic+1

Prevention and Risk Reduction

True prevention of insulinoma is not currently possible, because most cases arise without clear lifestyle causes. However, some steps can reduce complications and support early diagnosis and better outcomes. PMC+1

1. Seek medical advice early for repeated unexplained sweating, shaking, or confusion, especially when fasting. MSD Manuals

2. Avoid long, unplanned fasts and extreme dieting if you already have unexplained low-sugar episodes. PMC+1

3. If you have MEN1 or another hereditary endocrine syndrome, attend regular endocrine check-ups and recommended imaging. PMC+1

4. Follow your personalized diet plan to reduce severe hypoglycemia attacks. PMC+1

5. Keep all appointments for imaging and lab tests to track tumor behavior and treatment effects. PMC+1

6. Take medicines exactly as prescribed and report new side effects quickly. FDA Access Data+2FDA Access Data+2

7. Avoid over-the-counter supplements that claim to “cure” cancer or repair the pancreas without solid evidence. erc.bioscientifica.com+1

8. Do not smoke, and limit alcohol to protect the liver, heart, and overall health during systemic treatments. MDPI+1

9. Maintain a healthy activity level (within safe limits for hypoglycemia) to support cardiovascular and mental health. PMC+1

10. Consider genetic counseling if there is a family history of endocrine tumors. PMC+1

When to See a Doctor

You should see a doctor urgently or go to emergency care if you have repeated episodes of sweating, tremor, confusion, blurred vision, or fainting, especially when your stomach is empty or after exercise. These symptoms can signal severe hypoglycemia, which can cause seizures, accidents, or brain injury if untreated. PMC+1

You should also seek specialist endocrine or oncology care if you already have a diagnosis of insulinoma and your usual pattern of low blood sugar changes, becomes more frequent, or does not respond to your rescue plan. New symptoms like weight loss, jaundice, or abdominal pain can signal tumor progression or treatment complications and should not be ignored. OUP Academic+1

Because you are a teenager, it is especially important to involve your parents or guardians in all decisions and to attend appointments with them, so that your care team can explain treatment options clearly and safely. PMC+1

What to Eat and What to Avoid

1. Eat small, balanced meals every 2–3 hours, combining whole-grain carbohydrates, lean protein, and healthy fats. Scribd+1

2. Choose slow carbohydrates such as brown rice, whole-grain bread, lentils, beans, and vegetables. Scribd+1

3. Include a source of protein (eggs, fish, poultry, yogurt, tofu, pulses) in each meal or snack. Scribd+1

4. Have a bedtime snack that contains complex carbohydrate and some protein to protect against night-time hypoglycemia. ResearchGate+2ECronicon+2

5. Drink water regularly and limit sugary sodas and juices to emergency hypoglycemia treatment only. MSD Manuals+1

6. Avoid large loads of refined sugar (sweets, candy, white bread, sugary drinks) that cause a rapid spike and then sharp fall in blood sugar. MSD Manuals+1

7. Limit very fatty, fried foods that may lead to weight gain when you are already eating frequently to prevent low sugar. Scribd+1

8. Avoid heavy alcohol drinking, which can worsen hypoglycemia risk and interact with many systemic therapies. MDPI+1

9. Be careful with caffeine (energy drinks, very strong tea or coffee), which can mask early hypoglycemia symptoms like palpitations and anxiety. PMC+1

10. Always check with your doctor before starting any “special” diet (keto, intermittent fasting, extreme calorie restriction), because these can be dangerous in insulinoma. PMC+1

Frequently Asked Questions

1. Is insulinoma cancer?
Most insulinomas are benign (non-cancerous) and do not spread, but a small percentage are malignant and can metastasize, especially to the liver. Even benign tumors can cause serious problems through hypoglycemia, so they need proper treatment and follow-up. PMC+1

2. Can insulinoma be cured completely?
Yes, many patients are cured when the tumor is found early and removed surgically with clear margins. Long-term follow-up is still needed in case of recurrence or new tumors, especially in people with genetic syndromes like MEN1. PMC+1

3. What if surgery is not possible?
If surgery is unsafe or the tumor has spread, doctors use combinations of somatostatin analogs, diazoxide, targeted therapies such as everolimus or sunitinib, PRRT, and sometimes chemotherapy to control blood sugar and slow tumor growth. Treatment is individualized in a multidisciplinary tumor board. PMC+2Dove Medical Press+2

4. Do I have to take medicines forever?
Some patients take medicines only for a short time before and after surgery; others with advanced disease may need long-term therapy. Doctors regularly review benefits and side effects and may change or pause medicines as the situation evolves. PMC+2MDPI+2

5. Can insulinoma come back after surgery?
Recurrence is uncommon after complete removal of a single benign tumor but can occur, especially in MEN1 or with microscopic residual disease. Regular follow-up with blood tests, imaging, and clinical review helps detect recurrence early. PMC+1

6. Is insulinoma related to diabetes?
Insulinoma causes too much insulin and low blood sugar, while type 1 and type 2 diabetes usually involve too little insulin or insulin resistance and high blood sugar. However, after major pancreatic surgery, some patients may develop diabetes due to loss of normal beta cells. MSD Manuals+1

7. Can I have a normal life with insulinoma?
Many people live active, full lives after proper treatment and education. Good blood-sugar control, regular follow-up, and support from family, school, or workplace are essential. For advanced cases, modern therapies help control symptoms for many years. PMC+2OUP Academic+2

8. Are somatostatin analog injections painful?
Lanreotide and long-acting octreotide are given as deep injections, which can cause brief pain, bruising, or lumps. Using correct technique, rotating injection sites, and allowing the medicine to reach room temperature can reduce discomfort. FDA Access Data+2FDA Access Data+2

9. Do these medicines cause diabetes or high blood sugar?
Somatostatin analogs and everolimus can sometimes raise blood sugar by reducing insulin release or causing insulin resistance. Doctors monitor glucose levels and may adjust dose, diet, or add diabetes medicines if needed. Dove Medical Press+3FDA Access Data+3FDA Access Data+3

10. Is PRRT radioactive and dangerous to others?
PRRT uses a radioactive drug, but the radiation is mostly targeted to tumor cells and falls quickly over time. Patients receive safety instructions about limiting close contact with others, especially children and pregnant women, for a short period after each dose. PMC+2FDA Access Data+2

11. Can teenagers or children get PRRT or targeted therapy?
Lutetium Lu-177 dotatate is now FDA-approved for somatostatin receptor-positive GEP-NETs in patients aged 12 years and older. Use of other targeted drugs in younger people is decided case by case and usually in specialized centers or clinical trials. FDA Access Data+2ESMO+2

12. Are there special risks for girls and young women?
Some treatments can affect fertility, menstrual cycles, or pregnancy. Teen girls and young women should discuss contraception, fertility preservation, and pregnancy planning with their care team before starting systemic therapy or radioligand treatment. FDA Access Data+3FDA Access Data+3FDA Access Data+3

13. Should I avoid pregnancy if I have insulinoma?
Pregnancy with insulinoma is rare and complex but possible with expert care. Hypoglycemia must be tightly controlled to protect mother and baby, and some drugs are avoided during pregnancy. Any pregnancy plan should be discussed very early with endocrinology, oncology, and obstetric teams. PMC+1

14. Are “natural cures” for insulinoma real?
No strong scientific evidence shows that herbal or “natural” products can cure insulinoma or replace surgery and evidence-based medicines. Some may interact with treatments or worsen hypoglycemia. Always talk to your doctor before trying any alternative therapy. erc.bioscientifica.com+2MDPI+2

15. Where can my family find trustworthy information?
Reliable information can be found on major endocrine and cancer-society websites, neuroendocrine tumor patient groups, and peer-reviewed medical articles. Your healthcare team can recommend resources that are up-to-date and written in language that is easy to understand. PMC+2MDPI+2
