Chemotherapy for thyroid cancer
Chemotherapy is the use of anti-cancer (cytotoxic) drugs to destroy cancer cells.
Chemotherapy is rarely used to treat cancer of the thyroid, but it may be used if the cancer comes back or has spread to other parts of the body in some cases.
In people with papillary or follicular thyroid cancer that has come back, chemotherapy is sometimes offered as part of a clinical trial.
Chemotherapy is occasionally used in people with anaplastic thyroid cancer. Your doctor can discuss with you whether chemotherapy will be appropriate for you.
