Treatment depends on the type of thyroid cancer.
Surgery is most often done. The entire thyroid gland is usually removed. If the doctor suspects that the cancer has spread to lymph nodes in the neck, these will also be removed.
Radiation therapy may be done with or without surgery. It may be performed by:
- Aiming external beam (x-ray) radiation at the thyroid
- Taking radioactive iodine by mouth
After treatment for thyroid cancer, you must take thyroid hormone pills for the rest of your life. The dosage is usually slightly higher than what your body needs. This helps keep the cancer from coming back. The pills also replace the thyroid hormone your body needs to function normally.
If the cancer does not respond to surgery or radiation, and has spread to other parts of the body, chemotherapy may be used. This is only effective for a small number of patients.
