What is the thyroid?

The thyroid is a small gland located at the base of your throat (near your Adam's apple) that regulates body functions such as heart rate, metabolism and the rate at which your body burns calories.

What is a thyroid nodule?

A thyroid nodule is a lump in the thyroid gland in your neck. More than 90% of all thyroid nodules are benign (non-cancerous). Some are actually cysts filled with fluid.

How common are thyroid nodules?

Almost 10% of adults will develop thyroid nodules in their lifetime. They are more common in women than in men. They also tend to run in families.
