Thyroid cancer

Thyroid cancer occurs in the cells of the thyroid — a butterfly-shaped gland located at the base of your neck, just below your Adam's apple. Your thyroid produces hormones that regulate your heart rate, blood pressure, body temperature and weight.

Although thyroid cancer isn't common in the United States, rates seem to be increasing. Doctors think this is because new technology is allowing them to find small thyroid cancers that may not have been found in the past.

Most cases of thyroid cancer can be cured with treatment.

Symptoms Causes Risk factors Complications Prevention

Thyroid cancer typically doesn't cause any signs or symptoms early in the disease. As thyroid cancer grows, it may cause:

  • A lump that can be felt through the skin on your neck
  • Changes to your voice, including increasing hoarseness
  • Difficulty swallowing
  • Pain in your neck and throat
  • Swollen lymph nodes in your neck

When to see a doctor

If you experience any these signs or symptoms, make an appointment with your doctor. Thyroid cancer isn't common, so your doctor may investigate other causes of your signs and symptoms first.
