What are thyroid tumors?

The thyroid gland is located in the front of the neck at the base of the throat. Thyroid tumors are either benign (noncancerous) or malignant (cancerous) growths. Examples of benign tumors are adenomas, which secrete thyroid hormone. Malignant tumors are more rare and are more common in women than in men. According to the American Cancer Society (ACS), about 44,670 cases of thyroid cancer were expected to be diagnosed in the U.S. in 2010.

What are thyroid adenomas?

Thyroid adenomas are small growths (nodules) that start in the cell layer that lines the inner surface of the thyroid gland. The adenoma itself secretes thyroid hormone.

Treatment may include surgery to remove part of the thyroid (the overactive nodule).
