Thyroid nodules are solid or fluid-filled lumps that form within your thyroid, a small gland located at the base of your neck, just above your breastbone.

When to see a doctor

Although most thyroid nodules are noncancerous and don’t cause problems, ask your doctor to evaluate any unusual swelling in your neck, especially if you have trouble breathing or swallowing. It’s important to evaluate the possibility of cancer.

Seek medical care if you develop signs and symptoms of hyperthyroidism, such as:

  • Sudden weight loss even though your appetite is normal or has increased
  • A pounding heart
  • Trouble sleeping
  • Muscle weakness
  • Nervousness or irritability

Also see your doctor if you have signs and symptoms that may mean your thyroid gland isn’t making enough thyroid hormone (hypothyroidism), which include:

  • Feeling cold
  • Feeling tired more easily
  • Dry skin
  • Memory problems
  • Depression
  • Verstopfung
