Routine screening for thyroid cancer is not necessary. If you have a family history of thyroid problems, your healthcare provider may want to check your thyroid gland with blood, x-ray, and other tests. Most cases are discovered during a routine physical examination when a painless lump is found in the thyroid. If the cancer has already spread, symptoms may include neck pain, hoarseness, or difficulty swallowing. A biopsy is done to diagnose thyroid cancer.
Chemotherapy uses anticancer drugs to kill the cancer cells.
