Prostate cancer 101

It is hard to believe that a gland no bigger than the size of a walnut can cause men such problems.

The main job of the prostate gland is to create part of the fluid that makes up semen. It is not a vital organ, and men can live the rest of their lives safely without it.

Where it’s located

The gland is located deep within the pelvis, between the rectum and the bladder. It surrounds the upper part of the urethra, the tube that allows urine to flow from the bladder and through the penis. It is surrounded by major arteries, veins, and sphincters that facilitate urinary control. It is also surrounded by tiny, delicate nerves called neurovascular or “nerve bundles.”


In a nutshell, this small, usually harmless gland lies right in the middle of all that controls a man’s urinary and reproductive functions.
