The thyroid is a butterfly-shaped gland in the base of your neck. It secretes hormones that are essential for regulating your body's metabolism.

Hurthle cell cancer is also called Hurthle cell carcinoma or oxyphilic cell carcinoma. Hurthle cell cancer is one of several types of cancers that affect the thyroid.

Hurthle cell cancer can be more aggressive than other types of thyroid cancer. Surgery to remove the thyroid gland is the most common treatment.
