Prostate cancer means cancer of the prostate gland. The prostate is located below the bladder, in front of the rectum. It is found only in males. The urethra, which carries urine, passes through the prostate. It produces the fluid that is required for healthy sperm. It is an uncontrolled and rapid growth of prostate cells. If cancer cells are spread to other organs, it is called metastatic prostate cancer.
