The prostate is a male sex gland that is located between the bladder and the rectum. Prostate cancer occurs commonly in older men and is the second leading cause of cancer death in men in the United States.
Prostate cancer is typically a disease of aging.
It may persist undetected for many years without causing symptoms. In fact, most men die with prostate cancer not from prostate cancer. Because prostate cancer develops over such a long period of time, any area that holds promise for prevention must be explored. It is currently believed that environmental factors may play a bigger role than genetic factors in the development of prostate cancer. Diet is one environmental factor that can be modified with the hope of reducing the risk of developing prostate cancer.
