Cancer is a disease in which abnormal cells in the body grow out of control. When cancer starts in the prostate, it is called prostate cancer. The prostate is a walnut-sized organ located just below the bladder and in front of the rectum in men. It produces fluid that makes up a part of semen.
Prostate cancer is the most commonly diagnosed cancer in
men, and second only to lung cancer in the number of cancer deaths.
