Overview for patients
The prostate gland lies just below the bladder in front of the rectum and surrounds the urethra (the tube that carries urine and semen through the penis and out of the body).
Prostate cancer is the second leading cause of death from cancer in men and almost all prostate cancers are adenocarcinomas (cancers that begin in cells that make and release mucus and other fluids). Prostate cancer often has no early symptoms and usually grows very slowly. Advanced prostate cancer can cause men to urinate more often or have a weaker flow of urine, but these symptoms can also be caused by benign prostate conditions. Most men with prostate cancer are older than 65 years.
