Hormone therapy treats prostate cancer by stopping the hormone testosterone from reaching the prostate cancer cells.
Testosterone is produced by the testicles and adrenal glands. One of its roles is to control the development and growth of the sexual organs, including the prostate gland. Normal levels of testosterone do not usually cause any problems, but if there are cancer cells in the prostate gland, testosterone can cause them to grow faster. In other words, testosterone 'feeds' the prostate cancer. If testosterone is taken away, the cancer cells shrink, wherever they are in the body.
Hormone therapy alone will not get rid of your prostate cancer but it can keep it under control for many months or years before you and your doctor may need to consider additional treatment options. It can also be used with other treatments to help make them more effective.
