What are the risk factors of prostate cancer?

Basically none. A few common genes have been found that increase risk, and a family history increases risk, but not strikingly. The reports about diet (milk, red / well-done meat) are so contradictory that i've decided to ignore them. People have look at sexual habits and history of infections and found little or nothing. The claim about vasectomy as a risk was discredited in the 1990s.
Risk Factors: The most common risk factors are: older age, family history (father or brother with prostate cancer), race (african-american men have higher incidence than caucasian men). Researchers are looking into other risk factors as well.
