Moderate Exercise May Lower Prostate Cancer Risk

“Men who regularly get moderate exercise may have a lower risk of developing prostate cancer -- including aggressive, fast-growing tumors, a new study finds. Researchers found that among 190 men who underwent biopsies for possible prostate cancer, those who exercised moderately -- the equivalent of three to six hours of walking per week -- were less likely to be diagnosed with the disease. Compared with their sedentary counterparts, these men were two-thirds less likely to have a biopsy positive for prostate cancer. In addition, men who got the equivalent of one to three hours of walking each week had an 86 percent lower chance of having an aggressive form of the cancer. The findings, which appear in the current issue of the Journal of Urology, do not prove that exercise helps prevent prostate cancer. But they could offer men yet more incentive to get active. ‘If you need one more reason to exercise, this could be one,’ said senior researcher Dr. Stephen J. Freedland, of the Duke University Prostate Center and the VA Medical Center in Durham, North Carolina.”
