There's no sure way to prevent prostate cancer. Study results often conflict with each other, and no clear ways to prevent prostate cancer have emerged. In general, doctors recommend that men with an average risk of prostate cancer make choices that benefit their overall health if they're interested in prostate cancer prevention.
However, you may still reduce your risk of prostate cancer by making healthy choices, such as exercising and eating a healthy diet.

Eat more fat from plants than from animals.
Increase the amount of fruits and vegetables you eat each day.
