antiandrogen therapy

(AN-tee-AN-droh-jen THAYR-uh-pee)
Treatment with drugs to block the action of androgens (male hormones) in the body. Androgens, such as testosterone, bind to proteins called androgen receptors, which are found in prostate cancer cells and in cells of some other tissues. Antiandrogen therapy keeps androgens from binding to these receptors and may keep cancer cells from growing. It is used to treat prostate cancer.
