If you're a man working to lose weight, here's some good news for you: A new study has found that losing weight reduces the risk of an aggressive form of prostate cancer.

According to an Associated Press report, after tracking the weight of nearly 70,000 men between 1982 and 1992, researchers from the American Cancer Society and the Duke University Prostate Center found that men who lost more than 11 pounds had a lower risk for aggressive prostate cancer than men whose weight remained the same over a decade.

Previous studies have found that obese men have a higher risk of developing aggressive prostate cancer. This study appears to be the first to indicate that recent weight loss can decrease that risk.

Check out the study, published in Cancer Epidemiology, Biomarkers & Prevention, this month.
