The Cavaliers' super point guard Kyrie Irving runs between five and 10 miles every game.

But according to a new study, working out does NOT protect even the most active black men from prostate cancer (and they're 40 percent more likely to develop the disease in the first place). But moderate or heavy exercise does slash the risk for whites by 53 percent. (Kyrie might have to trim his workouts now, after injuring his shoulder Sunday; he's expected to be sidelined for at least a month. ALL men should work out, though, to decrease heart disease, depression and other cancers.) So what's going on?

It seems genetics may be tipping the scales. But more research is needed to figure out why black men are more at risk. What do we know? Every guy can benefit from certain lifestyle choices that reduce the risk of prostate cancer:

1. Start with 1,000 IU of D-3 daily. When blood levels of D-3 dip, the risk of dying from prostate cancer rises.

2. Get friendly with broccoli, other green vegetables and slow-cooked tomatoes. They're full of nutrients that fight off prostate cancer.

3. Avoid red meats, all charred meats and chicken skin. Eating charbroiled and overcooked meats floods your body with as much of a prostate-damaging carcinogen called PhlP as a pack and a half of cigarettes. Also, eliminate all added sugars and sugar syrups, which just feed hungry cancer cells.
