prostate cancer - Hormonal Therapy When Cancer Has Spread Beyond The Prostate Gland: "Once prostate cancer has spread beyond the prostate gland localized therapies are no longer sufficient to stop the growth of the cancer and treatment generally involves a combination of both radiation therapy to kill the cancer cells and hormonal treatment to slow the growth of the cancer by cutting off its fuel supply.
The aim of hormonal therapy is to cut off the production of the male hormones, such as testosterone, which fuel the growth of prostate cancer, or to render them ineffective, and this essentially means castration, either surgically or by other medical means such as using an antiandrogen drug to block the circulation of male hormones in the blood."
