Prostate cancer is cancer that starts in the prostate gland. The prostate is a small, walnut-sized structure that makes up part of a man's reproductive system. It wraps around the urethra, the tube that carries urine out of the body.
Prostate cancer is the most common cause of death from cancer in men over age 75. Prostate cancer is rarely found in men younger than 40.
People who are at higher risk include:
- African American men, who are also likely to develop cancer at every age
- Men who are older than 60
- Men who have a father or brother with prostate cancer
Other people at risk include:
- Men who have been around Agent Orange
- Men who use too much alcohol
- Men who eat a diet high in fat, especially animal fat
- Tire plant workers
- Men who have been around cadmium
Prostate cancer is less common in people who do not eat meat (vegetarians).
A common problem in almost all men as they grow older is an enlarged prostate. This is called benign prostatic hyperplasia, or BPH. It does not raise your risk of prostate cancer. However, it can increase your PSA blood test results.
