Regular exercise reduces risk of prostate cancer: study

Regular exercise may help reduce the risk of prostate cancer, a new study suggests.

The conclusion was based on analysis of 190 men who had a prostate biopsy, according to the study appearing in the September issue of Journal of Urology on Sunday.

In the study, researchers at Duke University Medical Center found that those who were moderately active -- anything equivalent to walking at a moderate pace for several hours a week -- were significantly less likely to be diagnosed with prostate cancer.

The majority (58 percent) of the men in this study were sedentary, which means they exercised less than the equivalent of one hour per week of easy walking.

The study also found that exercise was associated with less aggressive disease in men who did develop prostate cancer.

"As the amount of exercise increased, the risk of cancer decreased," said lead author Dr. Jodi Antonelli, a urology researcher at the center.

The results contribute to the ongoing debate about how exercise affects prostate cancer risk, the researchers said in a press release accompanying the study.

"There have been dozens of studies about the value of exercise in lowering risk of prostate cancer, and some of them quite large, but the bottom line is that they've left us with mixed signals," said the news release.
