Thyroid Nodule

A thyroid nodule is a small lump or growth inside the thyroid gland, which sits in the front of the neck. It is a “discrete” area of tissue that looks different from the rest of the thyroid on scan or ultrasound. Most thyroid nodules are benign (non-cancerous), but a small number can be cancer. Because of this cancer risk, doctors usually evaluate any clearly seen or felt nodule. ThyCa+4American Thyroid Association+4Cleveland Clinic+4

A thyroid nodule is a small lump inside the thyroid gland in the front of your neck. It may be solid tissue, a fluid-filled cyst, or a mix of both. Most thyroid nodules are benign (non-cancer) and are found by chance during a neck exam or ultrasound. A small percentage can be cancer, so doctors usually check any new nodule carefully with blood tests, ultrasound, and sometimes a fine-needle biopsy.American Thyroid Association+1

Nodules may be “cold” (do not make extra hormone), “hot” or “toxic” (make too much thyroid hormone), or linked to thyroid cancer. Risk factors include age, female sex, family history, iodine imbalance, previous neck radiation, and autoimmune thyroid disease. Some nodules never change; others slowly grow, cause neck pressure, or affect swallowing, breathing, or voice. Treatment depends on size, growth, symptoms, hormone levels, and cancer risk.American Thyroid Association+1

Other names for thyroid nodule

Doctors may use several other names for a thyroid nodule. They may say “thyroid lump,” “thyroid mass,” or “thyroid growth” to describe the same problem. If there are many nodules, they may call it “multinodular goiter” or “nodular goiter,” which means an enlarged thyroid with several lumps. You may also see the term “thyroid lesion” in ultrasound or scan reports, which is another way to describe an abnormal area in the thyroid. Cleveland Clinic+2Family Doctor+2

Types of thyroid nodule

Thyroid nodules can be grouped in several ways: by number (single or many), by what they are made of (solid, cystic, or mixed), by how they work (hot or cold), and by whether they are benign or malignant. This kind of classification helps doctors decide which nodules are more likely to be cancer and which ones can be watched. NCBI+2PMC+2

1. Solitary (single) thyroid nodule
   A solitary nodule means only one lump is found in the thyroid. Some single nodules are benign, and a few are cancerous. Solitary nodules are often studied more closely because the chance of cancer can be slightly higher than in glands with many small nodules. NCBI+1

2. Multinodular goiter
   In a multinodular goiter, there are many nodules in an enlarged thyroid gland. Most of these nodules are benign and develop slowly over time, often due to long-standing stimulation of the thyroid. Even though most are harmless, doctors still check them, because cancer can sometimes be hidden among many nodules. Wikipedia+1

3. Solid nodule
   A solid nodule is made mostly of thyroid cells and tissue, with little or no fluid inside. Solid nodules may be benign growths, like adenomas, or malignant tumors. Ultrasound appearance and biopsy are important to tell the difference between benign solid nodules and thyroid cancer. NCBI+2PMC+2

4. Cystic nodule
   A cystic nodule contains mostly fluid. It may be a simple cyst or a degenerating older nodule that has broken down inside. Many cystic nodules are benign and may shrink after aspiration (draining), but those with solid pieces inside still need careful study to exclude cancer. Wikipedia+1

5. Mixed solid-cystic nodule
   Some nodules are partly solid and partly fluid-filled. These mixed nodules are common and can be benign or malignant. Ultrasound features, such as the pattern of the solid areas and the presence of tiny calcifications, help doctors decide if biopsy is needed. PMC+1

6. “Hot” (hyperfunctioning) nodule
   A “hot” nodule takes up more radioactive tracer than the rest of the thyroid on a nuclear scan and produces extra thyroid hormone. These nodules are usually benign and are a rare cause of hyperthyroidism (overactive thyroid). Because the cancer risk in a clearly hot nodule is very low, fine needle aspiration is often not necessary. PMC+1

7. “Cold” (nonfunctioning) nodule
   A “cold” nodule takes up less tracer on a thyroid scan and does not make much hormone. Most cold nodules are still benign, but almost all thyroid cancers appear as cold nodules. For this reason, cold nodules usually need more tests, such as ultrasound and biopsy. NCBI+1

8. Benign thyroid nodule
   Benign nodules are non-cancerous growths such as colloid nodules, benign adenomas, or simple cysts. They do not invade nearby tissues or spread to other parts of the body. Many benign nodules can be observed with regular check-ups, unless they grow large enough to cause pressure symptoms. Canadian Cancer Society+2Cleveland Clinic+2

9. Malignant thyroid nodule (thyroid cancer)
   A malignant nodule is a cancerous growth in the thyroid. Common types include papillary, follicular, medullary, and anaplastic thyroid cancers. These nodules can invade nearby structures and spread to lymph nodes or distant organs, so early detection and treatment are very important. ThyCa+2NCBI+2

Causes of thyroid nodule

1. Colloid nodule
   A colloid nodule is a benign overgrowth of normal thyroid tissue filled with a jelly-like substance called colloid. It often forms as the thyroid responds to hormone-regulating signals over many years. These nodules are very common and usually harmless but may grow large enough to be seen or felt. Wikipedia+1

2. Multinodular goiter due to long-term thyroid stimulation
   In some people, long-standing stimulation of the thyroid gland, for example by slightly low iodine intake or other factors, leads to many nodules forming over time. The gland becomes enlarged and nodular, a condition called multinodular goiter. NCBI+1

3. Hashimoto thyroiditis
   Hashimoto disease is an autoimmune condition in which the immune system attacks the thyroid. The chronic inflammation can cause an irregular, lumpy gland, and small nodules may form within the inflamed tissue. Hashimoto disease is a common cause of hypothyroidism and can coexist with benign or malignant nodules. MedlinePlus+2MedlinePlus+2

4. Graves disease with nodular changes
   Graves disease is an autoimmune cause of hyperthyroidism. Over time, some patients with Graves disease develop nodules within the overactive gland. Most of these nodules are benign, but they still need evaluation because thyroid cancer can rarely appear in this setting. MedlinePlus+1

5. Simple thyroid cyst
   A simple cyst can form when a small area of the thyroid fills with fluid. This may happen as older nodules break down or as small pockets of fluid appear within the gland. Simple cysts are usually benign but can cause discomfort or cosmetic concerns if they grow. American Thyroid Association+1

6. Hemorrhagic (bleeding) cyst
   Sometimes a nodule or cyst bleeds internally, causing sudden swelling and pain in the neck. The blood collects inside the nodule and makes it larger. Although frightening, this bleeding is usually benign, but the enlarged nodule still needs follow-up and sometimes drainage. American Thyroid Association+1

7. Follicular adenoma
   A follicular adenoma is a benign tumor made of thyroid follicular cells. It appears as a solid nodule and may look similar to follicular cancer on imaging and even on biopsy. Because of this, some follicular adenomas are removed surgically to make sure there is no cancer. NCBI+1

8. Hürthle cell adenoma
   Hürthle cell adenomas are a special type of benign follicular tumor with large, granular cells. On imaging and biopsy, they may resemble Hürthle cell carcinoma. This similarity means they are often treated more carefully, sometimes with surgery, to rule out malignancy. NCBI+1

9. Papillary thyroid carcinoma
   Papillary thyroid carcinoma is the most common type of thyroid cancer and often presents as a thyroid nodule. It usually grows slowly and often spreads first to nearby lymph nodes. Many papillary cancers have an excellent prognosis when found early and treated appropriately. ThyCa+2NCBI+2

10. Follicular thyroid carcinoma
    Follicular thyroid carcinoma is another type of differentiated thyroid cancer that may appear as a solid nodule. It tends to spread through the bloodstream to lungs or bones rather than lymph nodes. Distinguishing it from follicular adenoma usually requires examination of the whole nodule after surgery. ThyCa+2NCBI+2

11. Medullary thyroid carcinoma
    Medullary thyroid carcinoma arises from C-cells that produce calcitonin. It can occur by chance or as part of inherited syndromes such as multiple endocrine neoplasia type 2 (MEN2). A medullary cancer often appears as a nodule and may be linked with high blood calcitonin levels. ThyCa+1

12. Anaplastic thyroid carcinoma
    Anaplastic thyroid carcinoma is a rare but very aggressive thyroid cancer. It may develop from a pre-existing nodule or goiter and suddenly grow, causing a hard, painful, and fixed mass in the neck. Because it grows and spreads quickly, it needs urgent specialist care. ThyCa+2NCBI+2

13. Primary thyroid lymphoma
    Lymphoma can arise in the thyroid, especially in glands affected by long-standing Hashimoto thyroiditis. It presents as a rapidly enlarging, firm thyroid mass and can cause pressure symptoms. This type of nodule requires biopsy and specific cancer treatment such as chemotherapy. NCBI+1

14. Metastatic cancer to the thyroid
    Cancers from other organs, such as kidney, lung, or breast, can rarely spread to the thyroid and form nodules. These metastases may be single or multiple and often appear in patients with known cancer elsewhere. Biopsy and full body evaluation are needed when this is suspected. NCBI+1

15. Iodine deficiency
    In areas where iodine in food and water is low, the thyroid has to work harder to make hormones. This long-term stimulation can lead to thyroid enlargement and the development of nodules. Universal salt iodization has reduced this problem in many countries but it still exists in some regions. MedlinePlus+1

16. Past neck radiation exposure
    Radiation to the head and neck, especially during childhood, increases the risk of thyroid nodules and thyroid cancer many years later. This may include radiation therapy for other cancers or exposure from nuclear accidents. People with this history need careful thyroid follow-up. ThyCa+1

17. Inherited genetic syndromes
    Some inherited conditions, such as MEN2, familial adenomatous polyposis, or Cowden syndrome, increase the risk of thyroid nodules and cancer. In these syndromes, genetic changes affect how cells grow and divide, making nodules more likely. Family history is therefore very important in risk assessment. ThyCa+1

18. Subacute (de Quervain) thyroiditis
    Subacute thyroiditis is a painful inflammation of the thyroid, often following a viral illness. During healing, areas of the gland may become uneven or nodular. These lumps are usually temporary or benign, but sometimes they are checked with ultrasound to be sure. MedlinePlus+1

19. Pregnancy and hormonal changes
    Pregnancy and other major hormonal changes can cause existing nodules to grow or make new nodules more noticeable. Increased blood flow and hormone levels during pregnancy can stimulate the thyroid. Most pregnancy-related nodules are benign but should still be evaluated. Cleveland Clinic+1

20. Certain medicines and environmental goitrogens
    Some medicines, such as amiodarone and lithium, and some environmental chemicals can interfere with thyroid hormone production. Over time, this can lead to gland enlargement and nodules. Doctors usually review all medicines and exposures when someone is found to have a thyroid nodule. MedlinePlus+1

Symptoms of thyroid nodule

1. Feeling or seeing a lump in the neck
   The most common symptom is a lump in the front of the neck that you or your doctor can feel, or sometimes see in the mirror. Often it moves up and down when you swallow. Many people have no other symptoms and discover the nodule during a routine exam. Cleveland Clinic+2American Thyroid Association+2

2. Neck fullness or pressure
   Some nodules, especially large ones or multinodular goiters, cause a feeling of fullness, tightness, or pressure in the neck. You may notice this more when wearing a tight collar or scarf. This feeling comes from the enlarged thyroid pressing on nearby tissues. American Thyroid Association+1

3. Pain or discomfort in the neck
   Most nodules are painless, but some cause dull aching or tenderness in the front of the neck. Sudden pain and swelling can occur if a nodule bleeds internally or during inflammatory thyroiditis. Pain that spreads to the jaw or ear may also occur in some cases. American Thyroid Association+1

4. Difficulty swallowing (dysphagia)
   When a thyroid nodule presses on the esophagus (the food pipe), it can make swallowing solid foods or pills harder. You may feel like food “sticks” in your lower throat. This is more likely when the nodule is large or located in certain parts of the gland. American Thyroid Association+1

5. Shortness of breath or choking feeling
   Large nodules or goiters may press on the windpipe (trachea), especially when you lie flat. This can cause a choking feeling, noisy breathing, or shortness of breath with exercise or at night. Severe pressure on the airway is a warning sign that needs urgent medical review. American Thyroid Association+2Canadian Cancer Society+2

6. Hoarse or changed voice
   If a nodule affects the nerve that controls the vocal cords, your voice may become hoarse, weak, or rough. Sudden or progressive voice changes, especially with a hard, fixed neck mass, raise concern for thyroid cancer or nerve compression. NCBI+1

7. Frequent coughing or throat clearing
   Some people with thyroid nodules have a persistent dry cough or feel the need to clear their throat often. This may be due to mild pressure or irritation of the airway from the enlarged gland, even when breathing is normal. Cleveland Clinic+1

8. Sensation of a lump in the throat (globus)
   A thyroid nodule can create a feeling that something is stuck in the throat, especially when swallowing saliva. This “globus” sensation may come and go and can be bothersome even when tests show the airway is open. American Thyroid Association+1

9. Unintentional weight loss and increased appetite
   If a nodule is “hot” and produces extra thyroid hormone, you may lose weight without trying, even though you eat the same or more than usual. This occurs because excess thyroid hormone speeds up metabolism and energy use. Mayo Clinic+2City of Hope+2

10. Fast or irregular heartbeat (palpitations)
    Overactive nodules can cause a rapid or pounding heartbeat, irregular beats, or feeling like your heart is “racing.” These palpitations are common signs of too much thyroid hormone in the body. Mayo Clinic+2City of Hope+2

11. Nervousness, anxiety, or tremor
    Excess thyroid hormone from a toxic nodule can make you feel anxious, restless, or shaky. You may notice hand tremors or trouble sleeping. These symptoms reflect the effect of thyroid hormones on the nervous system. Mayo Clinic+2City of Hope+2

12. Heat intolerance and sweaty skin
    People with hyperfunctioning thyroid nodules often feel too warm compared with others. They may sweat more than usual and have warm, moist skin. This happens because thyroid hormones increase heat production in the body. Mayo Clinic+2City of Hope+2

13. Fatigue and low energy
    Some patients with thyroid nodules also have hypothyroidism, often due to Hashimoto disease. Low thyroid hormone levels can cause tiredness, low energy, and sluggish thinking. Even when hormone levels are normal, worry and disturbed sleep from neck symptoms can make people feel fatigued. MedlinePlus+2MedlinePlus+2

14. Weight gain and feeling cold
    If a nodule is associated with an underactive thyroid, you may gain weight easily and feel cold when others are comfortable. The slower metabolism from low thyroid hormone contributes to these symptoms. MedlinePlus+1

15. Swelling of face or legs and dry skin (with hypothyroidism)
    In nodules linked to chronic autoimmune hypothyroidism, people may notice puffy face, swelling in the legs, dry skin, hair loss, and constipation. These symptoms result from reduced thyroid hormone affecting many body systems. MedlinePlus+2MedlinePlus+2

Diagnostic tests for thyroid nodule

Doctors use a combination of exam, blood tests, imaging, and tissue tests to evaluate thyroid nodules and decide which ones may be cancer. Guidelines from thyroid societies stress careful step-by-step evaluation rather than relying on a single test. PMC+3PMC+3ThyCa+3

1. General physical examination (physical exam)
   The doctor starts with a full physical exam, checking your weight, pulse, blood pressure, and overall health. They look for signs of hyperthyroidism, such as fast heart rate, or hypothyroidism, such as slow reflexes. These clues help link the nodule to possible hormone problems. NCBI+2MedlinePlus+2

2. Neck inspection and thyroid palpation (physical exam)
   The neck is inspected from the front and side while you swallow, and the thyroid is gently felt with the fingers. The doctor notes the size, consistency (soft or hard), tenderness, and whether the lump moves when you swallow. Hard, fixed nodules or those stuck to other tissues are more concerning. American Thyroid Association+2Family Doctor+2

3. Lymph node examination (physical exam)
   The doctor feels the lymph nodes in the neck to check for enlargement, tenderness, or firmness. Swollen, hard, or fixed lymph nodes near a thyroid nodule may suggest spread of thyroid cancer and usually trigger further evaluation and imaging. ThyCa+2NCBI+2

4. Airway and breathing assessment (physical exam)
   Breathing is observed for noise or effort, and the doctor may listen with a stethoscope. They look for signs that the nodule or goiter is narrowing the windpipe, such as noisy breathing or shortness of breath when you raise your arms. Serious airway compromise requires urgent attention. American Thyroid Association+2Canadian Cancer Society+2

5. Swallowing test for thyroid movement (manual test)
   During the exam, you may be asked to take a sip of water and swallow while the doctor watches and feels the neck. A thyroid nodule usually moves up with swallowing because it is attached to the thyroid, which slides up and down. This simple maneuver confirms that the lump is in or near the thyroid. Family Doctor+2American Thyroid Association+2

6. Tracheal deviation assessment (manual test)
   The doctor gently feels the front of the neck to see if the windpipe (trachea) is pushed to one side. Large nodules or goiters can shift the trachea, which may show that the nodule is big enough to affect the airway and may need surgery even if it is benign. American Thyroid Association+2Canadian Cancer Society+2

7. Pemberton sign for thoracic inlet obstruction (manual test)
   In Pemberton sign, the patient lifts both arms above the head while the doctor observes for facial redness, swelling, or breathing difficulty. A positive test suggests that a large goiter or nodule is compressing blood vessels or the airway in the upper chest. This helps identify dangerous pressure effects. NCBI+1

8. Thyroid-stimulating hormone (TSH) blood test (lab/pathological)
   TSH is the key screening blood test for thyroid function. Low TSH suggests an overactive nodule or thyroid, while high TSH suggests an underactive gland. TSH results guide further testing, such as whether a thyroid scan is needed or whether the nodule is likely to be “hot” or “cold.” MedlinePlus+2NCBI+2

9. Free T4 and Free T3 tests (lab/pathological)
   Free T4 and Free T3 measure the main thyroid hormones in the blood. High levels suggest hyperthyroidism, which may be due to a toxic nodule. Low levels suggest hypothyroidism, often from Hashimoto thyroiditis. These tests help connect hormone symptoms to the presence of a nodule. MedlinePlus+2Cleveland Clinic+2

10. Thyroid autoantibody tests (lab/pathological)
    Tests for antibodies such as anti-TPO, anti-thyroglobulin, or TSH-receptor antibodies show whether the immune system is attacking the thyroid. Positive antibodies support diagnoses like Hashimoto or Graves disease, which are common backgrounds for nodular thyroid disease. MedlinePlus+2MedlinePlus+2

11. Serum calcitonin test (lab/pathological)
    Calcitonin is a hormone produced by C-cells. A high level can suggest medullary thyroid carcinoma, especially in people with nodules and a family history of MEN2. Testing calcitonin in selected patients can help detect this cancer early. ThyCa+1

12. Serum thyroglobulin test (lab/pathological)
    Thyroglobulin is a protein made only by thyroid tissue, both normal and cancerous. While it is mainly used to follow patients after thyroid cancer surgery, elevated levels in certain settings can support the presence of large amounts of thyroid tissue or tumor. ThyCa+1

13. Fine needle aspiration (FNA) cytology (lab/pathological)
    FNA uses a thin needle to withdraw cells from the nodule, usually guided by ultrasound. A pathologist examines the cells under a microscope to see if the nodule is benign, suspicious, or malignant. FNA is the key test for diagnosing thyroid cancer and has greatly reduced unnecessary surgery. OUCI+4NCBI+4NCBI+4

14. Core needle biopsy or surgical histopathology (lab/pathological)
    In some cases, especially when FNA results are unclear, a core needle biopsy or surgery to remove part or all of the nodule is done. The entire tissue sample is then examined in detail to look for invasion of capsule or vessels, which distinguishes benign from malignant tumors like follicular carcinoma. OUCI+2NCBI+2

15. Electrocardiogram (ECG) (electrodiagnostic)
    Because thyroid hormone strongly affects the heart, an ECG is sometimes done in patients with nodules and suspected hyperthyroidism. The test records the heart’s electrical activity and can show fast rate, rhythm problems, or other changes linked to excess or low thyroid hormone. MedlinePlus+1

16. Nerve conduction study or EMG for thyroid-related myopathy (electrodiagnostic)
    Rarely, people with longstanding thyroid hormone problems develop muscle weakness or nerve issues. In such cases, nerve conduction studies or electromyography (EMG) may be done to measure electrical activity in nerves and muscles, helping to separate thyroid-related weakness from other neurological diseases. MedlinePlus+1

17. Thyroid ultrasound (imaging test)
    Ultrasound is the main imaging test for thyroid nodules. It uses sound waves to show the size, number, and internal features of nodules, such as solid or cystic parts, margins, and calcifications. Certain patterns are linked to higher cancer risk, and ultrasound also guides FNA biopsy. NCBI+3PMC+3PMC+3

18. Ultrasound elastography (imaging test)
    Elastography is a special ultrasound technique that measures how stiff a nodule is. Cancers tend to be stiffer than benign nodules. Elastography can add extra information to standard ultrasound and may help decide which nodules need biopsy. PMC+2WAOCP Journal+2

19. Thyroid scintigraphy (radioiodine or technetium scan) (imaging test)
    A thyroid scan uses a small amount of radioactive iodine or technetium to see how the thyroid and nodule take up tracer. “Hot” nodules that take up more tracer are usually benign and may cause hyperthyroidism, while “cold” nodules that take up less tracer may carry a higher cancer risk. NCBI+2PMC+2

20. CT or MRI of neck and chest (imaging test)
    CT or MRI scans are used when large nodules or goiters extend behind the breastbone or press on the airway and blood vessels. These scans show the exact size and spread of the thyroid and its relationship to nearby structures, helping surgeons plan safe operations. NCBI+2American Thyroid Association+2

If you ever notice a new lump in your neck, trouble swallowing, breathing problems, or strong thyroid symptoms, it is important to see a doctor or endocrinologist. They can choose the right combination of these tests to find out what kind of thyroid nodule you have and whether it needs treatment or just careful follow-up.

Non-pharmacological treatments (therapies and other options)

1. Active surveillance with regular ultrasound
   This is “watchful waiting.” If the nodule looks benign and thyroid blood tests are normal, doctors may simply monitor it over time. You may have an ultrasound every 6–18 months to check size, shape, and blood flow. This avoids unnecessary surgery and drug side-effects while still keeping you safe, because any suspicious growth is picked up early.American Thyroid Association+1

2. Education and reassurance
   Learning that most thyroid nodules are non-cancerous reduces fear and stress. Your doctor explains ultrasound and biopsy results, what to expect, and when to return. Clear information helps you notice warning signs (such as rapid growth or new hoarseness) and improves long-term follow-up, which is part of good nodule care.American Thyroid Association

3. Lifestyle and weight management
   A balanced diet, regular physical activity, and good sleep do not directly shrink nodules, but they support overall hormone balance and reduce cardiovascular risks if you later need thyroid hormone or cancer drugs. Healthy habits also improve surgical outcomes and recovery if an operation becomes necessary.American Thyroid Association

4. Optimizing iodine intake by diet
   Iodine is needed to make thyroid hormone. Both too little and too much iodine can be linked to goiter and nodules. In many countries, iodized salt and normal food give enough iodine; very high intakes from seaweed or “thyroid support” supplements can increase risk of nodules and autoimmune thyroid disease. Doctors usually advise normal dietary iodine, not mega-doses.PMC+2Frontiers+2

5. Smoking cessation
   Smoking is associated with larger thyroid volumes and may worsen goiter and nodular disease. Stopping smoking improves general vascular and lung health and may slow thyroid enlargement over time. Smoking cessation programs, counseling, and nicotine replacement are non-surgical ways to support thyroid and whole-body health.American Thyroid Association

6. Stress management and mental health care
   Living with a “lump in the neck” can cause anxiety and health worries. Talking therapy, relaxation training, breathing exercises, and mindfulness can reduce stress, improve sleep, and help you cope with chronic follow-up. Good mental health support is especially important while you are waiting for biopsy results or monitoring a large but benign nodule.American Thyroid Association

7. Ultrasound-guided radiofrequency ablation (RFA)
   RFA is a minimally invasive procedure for benign symptomatic nodules. A thin needle probe is guided into the nodule under ultrasound, and high-frequency current gently heats and destroys tissue, which then shrinks over months. RFA can reduce nodule volume by 50–80% and relieve pressure symptoms, often without general anesthesia or hospital stay.PMC+2KJR Online+2

8. Ultrasound-guided laser ablation
   In this technique, very thin laser fibers are put into the nodule. Laser energy heats and destroys nodule cells while real-time ultrasound guides the procedure. It is used mainly for benign nodules that cause cosmetic or compression problems. The goal is to shrink the nodule while preserving the rest of the thyroid gland and avoiding surgical scars.www.elsevier.com

9. Microwave ablation
   Microwave ablation works like RFA but uses microwave energy to create heat inside the nodule. It can be faster and useful for solid, relatively large nodules. Swelling and mild pain are possible right after treatment, but serious complications are uncommon in experienced hands. Longer-term studies show good volume reduction and symptom relief.www.elsevier.com

10. High-intensity focused ultrasound (HIFU)
    HIFU uses focused sound waves from outside the neck to heat and damage nodule tissue, without needles. It is still less widely available and mainly used in selected centers. The aim is to treat benign nodules non-invasively, but treatment can be time-consuming and may need repeated sessions, and data are more limited than for RFA or ethanol ablation.www.elsevier.com

11. Percutaneous ethanol injection (PEI)
    PEI is especially effective for cystic or mostly fluid nodules. Under ultrasound, a needle removes the cyst fluid and a small amount of sterile alcohol is injected back to scar the cavity, so it cannot refill easily. This can greatly reduce nodule size and symptoms with low cost and minimal downtime.PMC+1

12. Other sclerosing injections (e.g., polidocanol)
    In some centers, other sclerosing (scarring) agents besides ethanol are being studied. These agents damage the inner lining of cysts and lead to collapse and fibrosis. Evidence is more limited than for ethanol, so this is usually reserved for research or very selected patients who cannot receive standard treatments.www.elsevier.com

13. Combination ablation (e.g., ethanol + RFA)
    For complex nodules with both solid and cystic parts, doctors may first drain and inject ethanol into the fluid part and then use RFA on the solid part. Combining techniques can improve volume reduction and symptom control in difficult nodules while still avoiding open surgery.www.elsevier.com

14. Fine-needle aspiration (FNA) with decompression of cysts
    FNA is mainly a diagnostic test, but when a nodule is cystic, simple aspiration of fluid can itself relieve pressure and cosmetic issues. Some cysts collapse and never refill. Others recur and need PEI or surgery. FNA also provides cells for cytology to rule out cancer.American Thyroid Association+1

15. Voice therapy after thyroid procedures
    Large nodules or their treatments can sometimes affect the recurrent laryngeal nerve, causing hoarseness. A speech-language therapist can teach special voice exercises and safe speaking habits to reduce strain, improve voice quality, and support recovery of vocal cord function after surgery or ablation.American Thyroid Association

16. Neck and posture exercises
    After biopsy, ablation, or surgery, gentle neck stretching and posture training, guided by a physiotherapist, can reduce stiffness and scar tightness. This can improve comfort when swallowing or turning the head and may prevent chronic neck pain related to muscle guarding.American Thyroid Association

17. Management of vitamin D deficiency and other risk factors
    Low vitamin D is common in autoimmune thyroid disease and may be linked to thyroid dysfunction risk. Correcting deficiencies with sunlight exposure, diet, and medically supervised supplements can support bone and immune health while you manage nodules, although it does not replace specific thyroid treatment.PMC+2MDPI+2

18. Limiting unnecessary neck radiation
    Careful planning to avoid or reduce radiation to the neck (for example in dental or chest imaging) may help lower long-term thyroid damage and nodular change. Doctors follow radiation-safety rules to keep dose “as low as reasonably achievable,” especially in children and teens whose thyroids are more sensitive.American Thyroid Association

19. Multidisciplinary case discussion (tumor board)
    When a nodule is suspicious or cancer is found, a team of endocrinologists, surgeons, radiologists, pathologists, and oncologists may discuss your case together. This is not a physical treatment but leads to a personalized plan that chooses the safest mix of surgery, ablation, radioactive iodine, or systemic drugs.American Thyroid Association+1

20. Long-term follow-up scheduling systems
    Structured follow-up (reminder apps, recall lists, yearly checkups) is a practical non-drug “treatment” that keeps nodules under control. Regular visits let your doctor pick up small changes early, adjust tests, and give lifestyle advice before problems become serious.American Thyroid Association

Drug treatments for thyroid nodules and related conditions

⚠️ Important: Doses below are general adult ranges from FDA labeling and guidelines, not personal advice. Children and teens need different doses. Never start, stop, or change these medicines without a doctor.

Most medicines do not shrink a benign thyroid nodule directly. They treat problems that come with nodules: too much hormone, too little hormone, or thyroid cancer.

1. Levothyroxine (T4) – thyroid hormone replacement
   Levothyroxine is a synthetic form of T4. It is the standard drug for hypothyroidism and sometimes used to suppress TSH in selected patients with nodules or thyroid cancer. Typical adult doses range from 25–200 mcg once daily, adjusted by TSH. It replaces missing hormone and can slightly lower growth stimulus to some nodules, but routine suppression therapy for benign nodules is now not recommended because of heart and bone side-effects.FDA Access Data+2FDA Access Data+2

2. Liothyronine (T3)
   Liothyronine is synthetic T3. It acts faster and stronger than T4 and is used mainly for special diagnostic tests, short-term therapy, or in combination with T4 in selected cases. Typical adult doses are 5–25 mcg 1–3 times daily under specialist care. It works by directly replacing T3, but high levels can cause palpitations, anxiety, and arrhythmias, so it is not a standard long-term nodule treatment.FDA Access Data+1

3. Desiccated thyroid extract
   This is dried animal thyroid (e.g., Armour Thyroid) containing both T4 and T3. It is FDA-regulated but less predictable than pure levothyroxine. Doses are usually expressed in “grains,” taken once daily. It replaces thyroid hormone but can give variable hormone levels and is not first-line for nodules, though some long-term patients may be on it for hypothyroidism.FDA Access Data+1

4. Methimazole – antithyroid drug
   Methimazole blocks thyroid hormone production and is a key treatment for hyperthyroidism caused by toxic nodules or multinodular goiter. Typical starting adult doses are 10–40 mg daily in divided doses, later reduced. It lowers T4/T3 levels so symptoms such as tremor, weight loss, and palpitations improve. Main risks are rash, liver injury, and low white blood cells, so blood tests and prompt reporting of sore throat or fever are vital.FDA Access Data+2FDA Access Data+2

5. Propylthiouracil (PTU) – second-line antithyroid
   PTU also blocks thyroid hormone production and conversion of T4 to T3. It is mainly used when methimazole is not tolerated or in early pregnancy. Adult doses often start at 100–300 mg per day in divided doses. It helps control hormone excess from toxic nodules, but carries a serious risk of liver failure, so it is reserved for specific situations under close monitoring.FDA Access Data+2FDA Access Data+2

6. Sodium iodide I-131 (radioactive iodine, therapeutic)
   Radioactive iodine is swallowed as a capsule or liquid and taken up mainly by thyroid tissue. In toxic nodular goiter, it destroys overactive nodule cells over weeks to months, often curing hyperthyroidism. Adult doses for hyperthyroidism are usually 4–10 mCi (148–370 MBq), adjusted by nuclear medicine doctors. Side-effects include temporary neck pain, thyroiditis, and eventual hypothyroidism needing lifelong levothyroxine.FDA Access Data+1

7. Sodium iodide I-131 (diagnostic capsules)
   Lower-dose I-131 capsules are used for thyroid uptake tests and imaging, and to search for cancer spread. Typical adult diagnostic doses are much smaller (e.g., 5–100 microcuries). They help tell if a nodule is “hot” or “cold” and guide treatment, but are not used to treat benign nodules by themselves.FDA Access Data+1

8. Potassium iodide / Lugol’s solution
   Concentrated iodine solutions are sometimes given short-term before surgery in toxic nodular goiter to reduce hormone release and blood flow to the gland, making surgery safer. Doses and timing are carefully controlled by endocrinologists and surgeons. Used too long or without supervision, high iodine can actually worsen some thyroid problems.PubMed+2e-enm.org+2

9. Propranolol – beta-blocker
   Propranolol does not treat the nodule but quickly reduces symptoms of too much thyroid hormone, like fast heart rate, tremor, and anxiety, while other treatments take effect. Adult doses for hyperthyroid symptoms commonly range from 10–40 mg three to four times daily, adjusted to heart rate and blood pressure. Side-effects include low pulse, low blood pressure, fatigue, and bronchospasm in asthma.FDA Access Data+1

10. Other beta-blockers (e.g., atenolol, metoprolol)
    Once-daily beta-blockers are sometimes preferred for convenience. They calm the cardiovascular system stressed by excess thyroid hormone until radioactive iodine, surgery, or antithyroid drugs have worked. They are chosen and dosed individually based on heart disease, blood pressure, and other medicines.FDA Access Data

11. Thyrotropin alfa (Thyrogen)
    Thyrotropin alfa is an injected form of TSH used as a diagnostic and treatment aid in patients with thyroid cancer after thyroidectomy. It stimulates any remaining thyroid tissue or cancer to take up radioactive iodine without forcing the patient to stop hormone tablets and become hypothyroid. Typical dosing is 0.9 mg intramuscularly on two consecutive days. Side-effects may include nausea, headache, and temporary swelling in metastatic lesions.FDA Access Data+2FDA Access Data+2

12. Sorafenib (Nexavar) – tyrosine kinase inhibitor (TKI)
    Sorafenib is an oral targeted cancer drug for adults with progressive differentiated thyroid cancer that no longer responds to radioactive iodine. Usual adult dosing is 400 mg twice daily, with adjustments for side-effects. It blocks multiple kinases involved in tumor blood-vessel growth and cell signaling. Common side-effects are hand–foot skin reaction, diarrhea, fatigue, high blood pressure, and risk of bleeding or heart problems.FDA Access Data+2FDA Access Data+2

13. Lenvatinib (Lenvima) – TKI
    Lenvatinib is another oral TKI for advanced, radioactive-iodine-refractory differentiated thyroid cancer. It inhibits VEGF and other pathways that drive tumor growth. Dosing is weight-based once daily and adjusted for kidney function and side-effects like hypertension, diarrhea, weight loss, and protein in urine. It significantly improves progression-free survival but requires close specialist monitoring.FDA Access Data+2FDA Access Data+2

14. Cabozantinib (Cabometyx) – TKI
    Cabozantinib is used in certain patients with advanced differentiated or medullary thyroid cancer after other therapies fail. It blocks MET, VEGFR2, and other kinases. Recommended adult doses (e.g., 60 mg once daily) are adjusted for tolerance. Side-effects include diarrhea, mucositis, fatigue, high blood pressure, and risk of bleeding or fistula, so it is used only under oncology supervision.FDA Access Data

15. Vandetanib (Caprelsa) – TKI
    Vandetanib is indicated for unresectable, progressive medullary thyroid cancer. It is taken as a daily tablet (commonly 300 mg) and targets RET, VEGFR, and EGFR pathways. It can prolong the QT interval on ECG and cause skin rash, diarrhea, and eye problems, so patients require regular heart and eye monitoring.FDA Access Data+2FDA Access Data+2

16. Selpercatinib (Retevmo) – selective RET inhibitor
    Selpercatinib is a highly selective RET kinase inhibitor for RET-mutated medullary thyroid cancer and RET-fusion thyroid cancers that need systemic treatment. It is taken orally, with doses based on body weight. It can shrink tumors and control disease, but can cause liver enzyme elevation, high blood pressure, and QT prolongation, so regular labs and ECGs are needed.FDA Access Data+1

17. Pralsetinib (Gavreto) – selective RET inhibitor
    Pralsetinib is another RET-targeted drug for adults and teens with RET-mutant medullary thyroid cancer and RET-fusion thyroid cancer that is advanced or metastatic. It blocks RET-driven signaling, helping slow or shrink tumors. Common side-effects include constipation, high blood pressure, and neutropenia. It is given only in specialized oncology centers.FDA Access Data

18. Systemic chemotherapy (e.g., doxorubicin-based regimens)
    Conventional chemotherapy is rarely used for differentiated thyroid cancer but may be considered in anaplastic or highly aggressive disease. Drugs like doxorubicin damage DNA and rapidly dividing cells but also affect healthy tissues, leading to hair loss, nausea, low blood counts, and heart risk. They are reserved for life-threatening cancers, not simple benign nodules.American Thyroid Association

19. Immune checkpoint inhibitors (e.g., pembrolizumab, in selected cases)
    In some patients with advanced or anaplastic thyroid cancers expressing certain markers, immunotherapy can be used. These drugs help the immune system recognize and attack cancer cells. They are given intravenously at set intervals and can cause immune-related side-effects such as inflammation of the lungs, gut, liver, or endocrine glands.American Thyroid Association

20. Supportive medicines (analgesics, anti-nausea drugs, bone and heart protectors)
    Pain relievers, antiemetics, blood-pressure drugs, and bone-protective agents do not treat the nodule itself but help patients tolerate surgery, radioactive iodine, or TKIs. Correct supportive medication use improves quality of life and allows better adherence to main cancer or thyroid therapies.American Thyroid Association

Dietary molecular supplements

Research on supplements for thyroid nodules is still evolving, and they must not replace standard care.

1. Iodine (only in deficiency)
   In areas with low iodine intake, correcting deficiency through normal foods or carefully dosed supplements can reduce goiter and nodule risk. But in iodine-sufficient or high-iodine areas, extra iodine can increase problems, including autoimmune thyroiditis and some thyroid cancers. Any iodine supplement should be guided by urine iodine and medical advice, not self-medication.Bangladesh Journals Online+3PMC+3Frontiers+3

2. Selenium
   Selenium is a trace mineral used by antioxidant enzymes in the thyroid. Several trials suggest selenium supplements may reduce thyroid antibody levels and slightly improve symptoms in autoimmune thyroiditis, with mixed effects on nodules. Doses in studies are usually 100–200 mcg/day. Too much selenium can cause hair loss and nail changes, so medical supervision is needed.Examine+3PMC+3MDPI+3

3. Myo-inositol plus selenium
   Myo-inositol is a signaling molecule that helps TSH signaling inside thyroid cells. Studies combining myo-inositol with selenium have shown improved TSH levels, lower antibodies, and in early research, reduced size and stiffness of some benign nodules. Typical study doses are myo-inositol 600–1200 mg plus selenium 83–200 mcg daily. More large trials are needed before routine use.ResearchGate+4PMC+4ijmdat.com+4

4. Vitamin D
   Vitamin D plays roles in bone and immune health. Many studies show that people with autoimmune thyroid disease often have low vitamin D levels, and supplementation may improve antibody levels and thyroid function in some. Doses vary widely (often 1000–4000 IU/day in adults). Too much vitamin D can harm kidneys and raise calcium, so blood levels should be checked.www.elsevier.com+4PMC+4MDPI+4

5. Zinc
   Zinc is involved in thyroid hormone production and conversion. Mild deficiency can worsen hypothyroid symptoms. Controlled supplementation (for example, 10–30 mg/day in adults) may help if deficiency is proven, but has not been shown to shrink nodules directly. High doses can cause nausea and reduce copper levels.American Thyroid Association

6. Iron (when deficient)
   Iron deficiency can impair thyroid hormone synthesis and is common in people with heavy menstrual bleeding or low-iron diets. Treating iron deficiency with diet and prescribed supplements can normalize thyroid tests and energy, but iron should be taken exactly as directed to avoid stomach upset and constipation.American Thyroid Association

7. Omega-3 fatty acids
   Omega-3s from fish oil or algae have anti-inflammatory effects. They may help general cardiovascular and immune health in patients on thyroid cancer drugs, which can raise cardiovascular risk. They are not proven to reduce nodules but can be part of an overall heart-healthy plan.American Thyroid Association

8. Vitamin B12
   Low B12 often coexists with autoimmune thyroid disease and can cause fatigue and nerve symptoms. Replacement with oral tablets or injections restores levels and may improve overall wellbeing, but does not directly affect nodule size. It is useful to check and correct B12 if symptoms suggest deficiency.American Thyroid Association

9. Probiotics and prebiotic fiber
   Gut health influences absorption of thyroid medication and some nutrients. Probiotics and high-fiber foods support a diverse microbiome, which may help stable hormone levels and overall immune balance. Evidence for direct nodule effects is limited, but gut support is reasonable as part of whole-person care.MDPI+1

10. Antioxidant-rich foods (rather than pills)
    Fruits, vegetables, nuts, and whole grains provide natural antioxidants that help protect cells from oxidative stress, which is increased in many thyroid conditions. Whole foods are preferred over high-dose antioxidant pills, which sometimes show no benefit or even harm.American Thyroid Association

Immunity-supporting and regenerative / stem-cell–related approaches

Right now, there are no approved stem cell drugs or “immune booster” medicines that specifically and safely shrink benign thyroid nodules. Research is ongoing, mainly in thyroid cancer and animal models of hypothyroidism.

Scientists are exploring:

• Advanced targeted cancer drugs (TKIs, RET inhibitors) that also modify the tumor micro-environment and anti-tumor immunity in advanced thyroid cancers.

• Immune checkpoint inhibitors that activate T-cells against anaplastic or metastatic cancers in selected cases.

• Experimental stem-cell therapies (e.g., transplanting thyroid or mesenchymal stem cells in animals) to restore thyroid function, still far from standard human use.

These approaches are only used within clinical trials or in very specialized oncology care and are not suitable for self-treatment or for simple benign nodules.FDA Access Data+3American Thyroid Association+3FDA Access Data+3

Surgical treatments for thyroid nodules

1. Lobectomy (hemithyroidectomy)
   The surgeon removes the lobe of the thyroid that contains the nodule. This is common for a single suspicious or growing nodule. It allows full microscopic examination to confirm benign or malignant disease. Many people keep normal thyroid function after lobectomy and may not need lifelong hormone pills.American Thyroid Association+1

2. Total thyroidectomy
   The whole thyroid gland is removed. This is usually done for confirmed thyroid cancer, very large multinodular goiter causing major compression, or nodules in both lobes. After surgery, the body cannot make thyroid hormone, so patients need lifelong levothyroxine. Risks include damage to the parathyroid glands and vocal cord nerves.American Thyroid Association+1

3. Near-total or subtotal thyroidectomy
   In some cases, almost all gland tissue is removed, leaving a very small remnant. This can reduce risk in specific anatomical situations while still allowing radioactive iodine ablation if needed. Hormone replacement is usually still required.American Thyroid Association+1

4. Minimally invasive or endoscopic thyroidectomy
   Some centers use smaller incisions or remote-access (axillary or behind-ear) approaches to reduce neck scarring. The steps are similar to open surgery, but instruments and cameras are used. This is mainly cosmetic and must still follow strict safety rules to protect nerves and parathyroids.American Thyroid Association

5. Central neck dissection (with cancer)
   If a nodule is cancer and has spread to central neck lymph nodes, the surgeon may remove those lymph nodes at the same time as thyroidectomy. This helps lower recurrence risk but raises the chance of temporary low calcium and nerve injury, so it is reserved for proven or very likely spread.American Thyroid Association+1

Prevention: 10 practical steps

1. Keep iodine intake in the normal range, avoiding extreme low or high intakes.

2. Avoid unnecessary neck radiation and follow safety advice for medical imaging.

3. Do not smoke; seek help to quit if needed.

4. Maintain a healthy weight and active lifestyle.

5. Treat autoimmune thyroid disease, vitamin D and iron deficiency early.

6. Have regular checkups if you have a family history of thyroid disease or prior neck radiation.

7. Avoid unregulated “thyroid booster” or high-dose iodine supplements from the internet.e-enm.org+2Nature+2

8. Control other hormone and metabolic conditions (e.g., diabetes, high cholesterol).

9. Eat a varied diet rich in whole foods, not ultra-processed foods.

10. Follow your doctor’s advice on follow-up for any known nodule; do not skip ultrasounds or blood tests.American Thyroid Association

When to see a doctor

You should see a doctor (usually a primary care doctor or endocrinologist) if you:

• Feel or see a new lump in the front of your neck.

• Notice a nodule that seems to be growing quickly.

• Have trouble swallowing, breathing, or feel pressure in your neck.

• Develop hoarseness, voice changes, or a cough that will not go away.

• Have symptoms of too much thyroid hormone (nervousness, weight loss, heat intolerance, fast heartbeat) or too little (fatigue, weight gain, feeling cold, dry skin, constipation).

• Have a family history of thyroid cancer, MEN2, or RET mutations.

• Had significant neck radiation as a child.

Urgent care is needed if breathing or swallowing suddenly becomes very difficult, or if a nodule becomes suddenly painful and rapidly enlarged, which may suggest bleeding or infection.American Thyroid Association+1

What to eat and what to avoid

What to eat (with doctor’s guidance):

1. A balanced diet with vegetables, fruits, whole grains, and lean protein to support overall health.

2. Foods with normal iodine amounts (e.g., moderate iodized salt, dairy, eggs, some fish) if you are not on a low- or high-iodine plan.PMC+2Frontiers+2

3. Selenium-rich foods like Brazil nuts (small amounts), fish, and whole grains.

4. Sources of vitamin D and calcium, such as oily fish, fortified foods, or supervised supplements.PMC+2Frontiers+2

5. Iron-rich foods (lean meat, beans, lentils) and vitamin C-rich foods to help absorb iron.

What to limit or avoid (unless your doctor says otherwise):

1. High-iodine seaweeds (kelp, kombu) and iodine mega-dose tablets, especially in autoimmune thyroid disease.e-enm.org+2Nature+2

2. Unregulated “thyroid support” pills containing unknown hormone or huge iodine doses.

3. Very high intake of raw goitrogenic vegetables (large amounts of raw cabbage, kale, etc.); cooked forms are usually fine.

4. Excess alcohol, which harms liver and bone health.

5. Heavy ultra-processed foods high in sugar, salt, and trans fats, which worsen cardiovascular risk if you later need thyroid drugs or TKIs.American Thyroid Association

Frequently asked questions (FAQs)

1. Are most thyroid nodules cancer?
   No. Most nodules are benign. Only a small percentage are cancer, and ultrasound plus FNA biopsy are very good at identifying which nodules need surgery.American Thyroid Association+1

2. Can a benign thyroid nodule turn into cancer later?
   Most benign nodules stay benign. However, because a small risk exists and new nodules can appear, doctors suggest regular follow-up with ultrasound and exam, especially if you have risk factors.American Thyroid Association

3. Do all nodules need to be removed?
   No. Small, benign, symptom-free nodules are usually watched. Surgery or ablation is considered when nodules are large, growing, causing pressure or cosmetic problems, or show cancer risk.American Thyroid Association+2www.elsevier.com+2

4. Can thyroid medicine shrink my nodule?
   In the past, TSH-suppressive levothyroxine was used, but modern guidelines say it gives little benefit and may harm the heart and bones. It is rarely used long-term just for benign nodules now.PubMed+1

5. Do nodules always change thyroid hormone levels?
   No. Many nodules are “cold” and do not affect hormone levels. “Hot” or “toxic” nodules do produce extra hormone and can cause hyperthyroidism, which needs treatment.American Thyroid Association+1

6. Is radiofrequency ablation safer than surgery?
   For selected benign nodules, RFA can be a safe alternative with fewer scars and shorter recovery, but it is not suitable for all nodules, especially suspected cancers. Choice depends on size, location, and local expertise.PMC+2KJR Online+2

7. Will I need thyroid hormone forever after surgery?
   After total thyroidectomy, yes, you need lifelong levothyroxine. After lobectomy, some people keep normal function; others develop hypothyroidism and need hormone replacement.FDA Access Data+1

8. Can diet alone cure a thyroid nodule?
   No. Healthy food supports overall health but cannot reliably shrink nodules or cure thyroid cancer. Diet is an add-on, not a replacement for medical tests and treatments.PMC+1

9. Are supplements like selenium and myo-inositol enough to treat nodules?
   Current studies show possible benefits as adjunct therapy, such as improved thyroid tests or smaller nodules in some patients, but evidence is not strong enough to replace standard care. Always discuss doses and interactions with your doctor.ResearchGate+4PMC+4MDPI+4

10. Do targeted cancer drugs cure thyroid cancer?
    TKIs and RET inhibitors often shrink tumors and slow progression in advanced disease, but they rarely cure cancer. They are powerful drugs with serious side-effects and are used when surgery and radioactive iodine are not enough.FDA Access Data+4FDA Access Data+4FDA Access Data+4

11. Is it safe for a teenager to take thyroid cancer drugs?
    Some drugs, like selpercatinib and pralsetinib, have pediatric indications in specific genetic cancers, but treatment is always in specialist centers with close monitoring. Never use any of these medicines without an oncology team.FDA Access Data+1

12. Can pregnancy affect thyroid nodules?
    Nodules may enlarge slightly during pregnancy because of hormonal changes. Most benign nodules are just monitored. Definitive surgery is often delayed until after delivery unless cancer is strongly suspected.American Thyroid Association+1

13. Are thyroid nodules common in iodine-sufficient countries?
    Yes. Even where iodized salt is used, nodules remain common, especially with age and in women. Iodine balance, autoimmunity, genetics, and other factors all play roles.PMC+1

14. Can a normal blood test rule out thyroid cancer?
    No. Thyroid hormone levels may be completely normal in both benign nodules and cancer. Ultrasound and FNA cytology are the main tools for cancer risk assessment.American Thyroid Association+1

15. What is the safest approach overall for a thyroid nodule?
    The safest path is personalized care: proper evaluation with blood tests, ultrasound, and biopsy; shared decision-making with an endocrinologist; and regular follow-up. Avoid self-medicating with hormones, iodine, or “immune boosters,” and always talk to a doctor if symptoms change.American Thyroid Association+2PubMed+2
