Thyroid Cancer

Thyroid cancer occurs when cells of the thyroid gland grow uncontrollably to form tumors that can invade the tissues of the neck spreading themselves to the surrounding tissues of the neck as well as the bloodstream and then to other parts of the body. The most common types of thyroid gland cancer originate in the cells responsible for thyroid hormone production. The general term for cancers that come from glandular tissue is adenocarcinoma.
