Prostate cancer does not usually cause any symptoms until the cancer has grown large enough to put pressure on the tube that carries urine from the bladder out of the penis (urethra).

Signs that the cancer may have spread include bone and back pain, a loss of appetite, pain in the testicles and unexplained weight loss.
