Exercise May Prevent Protate Cancer

According to a new study released today by Duke University Medical Center men who were moderately active were significantly less likely to be diagnosed with prostate cancer.  Moderately active was defined as anything equivalent to walking at a moderate pace for several hours a week.

The researchers looked at men who had a prostate biopsy and 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, the study’s lead author said in a news release.

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.

Prostate cancer is the third most common cause of death from cancer in men of all ages and is the most common cause of death from cancer in men over 75 years old. Prostate cancer is rarely found in men younger than 40.

Men at higher risk include African-America men older than 60, farmers, tire plant workers, painters, and men exposed to cadmium. The lowest number of cases occurs in Japanese men and those who do not eat meat (vegetarians).

Prostate cancers are grouped according to tumor size, any spreading outside the prostate (and how far), and how different tumor cells are from normal tissue. This is called staging. Identifying the correct stage may help the doctor determine which treatment is best.
