Thyroid cancer is a type of cancer that develops in the cells of the thyroid gland, which is located at the base of the neck and produces hormones that control metabolism. Symptoms of thyroid cancer may include a lump or swelling in the neck, hoarseness or difficulty speaking, difficulty swallowing, pain in the neck or throat, swollen lymph nodes in the neck, and changes in voice quality. Risk factors for thyroid cancer include being female, exposure to radiation, family history of thyroid cancer or certain genetic conditions, and certain medical conditions. Treatment options for thyroid cancer depend on factors such as the type, size, and stage of cancer, but may include surgery, radioactive therapy, thyroid hormone therapy, external beam radiation therapy, or targeted therapy. Early detection and treatment are important for improving outcomes and reducing the risk of complications.
