Thyroid Cancer

Thyroid cancer is the most common endocrine malignancy, although the lifetime risk of developing thyroid cancer is low. It is usually detected as a mass or nodule found during physical examination; however, incidental detection on imaging is also common. Initial laboratory testing includes thyroid stimulating hormone (TSH), also called thyrotropin, and free thyroxine (T4). There are no specific serum tumor markers for most thyroid cancers, although serum calcitonin concentrations may be increased by medullary thyroid cancer. Fine needle aspiration (FNA) is used to obtain tissue for definitive diagnosis of suspicious thyroid nodules and to determine the need for surgery.
