THYROTROPIN ALFA helps check your body for the return of thyroid cancer after treatment. It works by measuring the level of a substance in your body (thyroglobulin) that is produced if cancer cells are present. It is also used to help treat thyroid cancer. It works by helping thyroid tissue cells take up radioactive iodine, which slows or stops the spread of cancer cells.
