Prostate Cancer

Frequently Asked Questions

7. What are the risk factors for prostate cancer?

Age is the most important risk factor for prostate cancer. The disease is extremely rare in men under age 40, but the risk increases greatly with age. More than 60 percent of cases are diagnosed in men over age 65. The average age at the time of diagnosis is 65.

Race is another major risk factor. In the United States, this disease is much more common in African American men than in any other group of men. It is least common in Asian and American Indian men. A man's risk for developing prostate cancer is higher if his father or brother has had the disease.

Diet also may play a role.
