A new study has found that three hours or more of vigorous biking, tennis, jogging or swimming seems to lower a patients risk by as much as 61 percent.
But scientists add, even moderate physical activity, appears to lower the overall risk of dying from any cause.
They suggest men with prostate cancer could do some physical activity even if it is as little as 15 minutes a day of walking, jogging or biking.
They theorize that people who exercise have a decreased likelihood of inflammation or that they could have healthier immune systems.
