The prostate gland is one of the male sex glands. The prostate makes the fluid that liquefies the semen and carries the sperm.
Prostate cancer is the abnormal growth of cells in the prostate.
With the exception of skin cancers, it is the most common cancer in men. Prostate cancer is found mainly in older men, although it is found on occasion at an earlier age. As men get older, the prostate may get bigger. This swelling or enlargement blocks off the urethra. This blockage can cause difficulty in urinating or it may interfere with sexual function.
