The type of treatment you will have will depend on the stage of the cancer, the size of the tumor, your age, and overall condition. The main prescription drug therapies used to treat prostate cancer are hormonal therapies.
Prostate cells need male hormones, called androgens, to grow and work properly. The aim of hormonal therapy is to reduce the amount of male hormones in your body so that prostate cells are not stimulated to grow. The most effective hormonal therapy is by surgical removal of the testes (bilateral orchiectomy). This is simple and effective, but irreversible. Often hormonal therapies are combined to achieve greater effects.
There are several different types of prescription hormonal therapies, including:
Luteinizing hormone-releasing hormone (LHRH) analogs
Common names include:
These medications decrease the production of the male hormone, testosterone, from your testicles. These medications are given by injection into a muscle every 3 or 4 months.
Possible side effects include:
Common names include:
Anti-androgens prevent your body from using the male hormones, called androgens, that are made by your body. These medications are given by pill.
Possible side effects include:
