What is prostate cancer?

Diagram showing the prostate gland underneath the bladder.
  • Prostate cancer affects the prostate gland.
  • The prostate is a small, walnut-size gland under the bladder. It produces a thick, white fluid that mixes with sperm to make semen.
  • Prostate cancer is most common in men over the age of 50 or from a Black African or Caribbean background. Anyone with a prostate can get it.
  • How serious prostate cancer is depends on if it's spread to other parts of the body.
  • Prostate cancer can be successfully treated if it's diagnosed at an early stage.
  • Prostate cancer does not usually have any signs or symptoms at first. Later signs may include back, hip or pelvis pain, or difficulty maintaining an erection. You may also have problems peeing, but this could be a sign of other prostate problems.
