Thyroid stimulating hormones are used along with radioiodine to help detect and treat thyroid cancer. These medications work by stimulating your thyroid gland to make thyroid hormones using radioiodine, which helps detect the thyroid cancer or kill the cancerous thyroid cells. Thyroid stimulating hormones come as injections. Examples include Thyrogen (thyrotropin alfa). You can discuss with your oncologist about the best option for you.
