How is hormonal therapy used to treat prostate cancer?

Starve cancer cells: It is used to suppress testosterone (male hormone) that feeds cancer cells.

Different ways: Hormonal therapy is very effective in controlling the prostate cancer but is not curative. It is administered by injection with or without an oral pill. It is generally injected every 1 month, 3 months, 6 months, or given once a year, depending on which formulation is given.

Hormonal Therapy: Hormonal therapy works because the majority of prostate cancer cell require testosterone to grow. Removal of testosterone may be done with drugs (injected or by mouth) or removal of testes. Not all of the cells will respond as some cancer cells do not require testosterone. This is only to slow progression of cancer, not to cure it. Age, extent of disease, and other medical issues are taken in acct.

Castration: Hormone therapy turns off your testosterone. A nobel prize was awarded based on the observation that eunuchs do not develop prostate cancer. However, this treatment is not a cure. If you live long enough, hormones will eventually stop working.
