Prostate Cancer Prostate Cancer Prostate cancer is now the most common cancer in American men. One of every 10 American men will develop prostate cancer at some time in his life.
Prostate cancer is usually curable when caught and treated early.
However, many cases are not diagnosed until the disease is advanced. Since early prostate cancer causes no symptoms, it can only be detected by regular checkups. The prostate is a small gland in men, about the size and shape of a walnut. It wraps around the urethra, the tube that carries urine from the bladder out through the tip of the penis. The gland's main function is to make fluid for semen, which transports sperm.
