Prostate cancer happens when normal cells in the prostate gland change into abnormal cells and grow out of control. The prostate gland makes fluid that is part of semen. This gland sits below the bladder and in front of the rectum, and forms a ring around the urethra, the tube that carries urine out of the body.
Prostate cancer occurs most often in men older than 50 and often causes no symptoms at first.
But if symptoms do occur, they can include:
- Needing to urinate more often than usual
- A urine stream that is slower than usual
These symptoms can also be caused by conditions that are not prostate cancer. But if you have these symptoms, you should let your doctor or nurse know.
