Antihormone therapy is a form of treatment which suppresses selected hormones. This can be done with drugs, radiation, or even surgery. The suppression of certain hormones would be beneficial to the cancer patient, because certain hormones might prompt, or even help the growth of a tumor. Antihormone treatment can be specific to gender as well, such as antiestrogen or antitestosterone therapy. This would be beneficial in cancers relating to the genitals or sex organs.
