Thyroid cancer is cancer of the small butterfly-shaped gland in the neck that controls the metabolism. It occurs when cells mutate or change, resulting in abnormal cells multiplying in the thyroid and developing into a tumor. Around 726,000 people in the United States have thyroid cancer, according to figures from the CDC.
Symptoms of thyroid cancer include a lump in the neck that can be felt through the skin, changes to the voice, problems swallowing, pain in the neck and throat, and swollen lymph nodes in the neck. Risk factors for thyroid cancer include being female, exposure to high levels of radiation and certain hereditary syndromes.
Treatment of thyroid cancer usually involves surgery to remove the thyroid, removal of the lymph nodes, thyroid hormone therapy, radiation therapy, chemotherapy, and medication. Drug classes commonly used to treat thyroid cancer are thyroid preparations, anthracyclines, protein kinase inhibitors, and thyroid therapy.
