Prostate cancer results from the uncontrolled growth of abnormal cells in the prostate gland. This gland produces part of the fluid in semen. It is located below the bladder and in front of the rectum, near the base of the penis.
Prostate cancer is one of the most commonly diagnosed cancers in American men. Many other men have the disease, but have not been diagnosed. This is because prostate cancer has few symptoms early on.
