Understanding Prostate Cancer
About the Prostate
The prostate is about the size of a walnut and lies at the base of your bladder.
The front of your prostate surrounds your urethra, the tube that carries urine from your bladder and out through your penis. Any change in the size or shape of the prostate can narrow this tube, making it difficult for you to urinate. The back of your prostate presses against your rectum.
