What Is Prostate Cancer?

Anatomical view of testicles and prostate

First, it’s helpful to know a little about the prostate.

Your prostate is a walnut-sized gland that produces a fluid that protects your sperm. Located between your bladder and your rectum, the prostate wraps around your urethra, the tube that carries urine from your bladder and out through your penis.

Sperm are manufactured in the testicles. During sexual activity, sperm pass through the prostate gland, where they mix with seminal fluid before being released from the penis during ejaculation.

Prostate cancer occurs when cancer cells begin to grow in the prostate tissue. If those cells travel out of the prostate to distant parts of the body, it is called metastatic prostate cancer.
