Findings of a new study, published in the Journal of Urology, have revealed that men who incorporate some form of moderate exercise in their routines regularly lower their risk of developing prostate cancer, as well as aggressive tumors which grow rapidly.

190 men who had undergone biopsies for prostate cancer were considered for the sake of the study. It was discovered that those who exercised moderately, like 3-6 hours of walking each week, were two-thirds less likely to get a positive prostate cancer biopsy. Also, men who got one to three hours of moderate activity in a week were at 86% lower risk of developing an aggressive form of cancer.

"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.

The findings need more research and study before they can be confirmed, but these are being considered valuable at a time when prostate cancer has become one of the biggest medical threats.
