Exercise can prevent prostate cancer

Exercise is not only good for the heart, it's also good for preventing prostate cancer; a new study shows that older men who exercise regularly have a much lower risk of dying from prostate cancer. The study found that men over 65 who engage in more than three hours of vigorous exercise per week, such as running, biking, and swimming, can reduce their risk of being diagnosed with advanced prostate cancer or dying from the disease by nearly 70 percent.

Although many recent studies have shown that exercise can reduce men's risk of prostate cancer, researchers believe that this study is one of the largest to date and provides detailed information on the intensity of exercise that is effective in preventing prostate cancer.
The researchers studied more than 47,000 men who participated in the Health Professionals Follow-up Study to analyze their exercise and prostate cancer diagnosis and progression. The men were followed from 1986 to 2000 and asked to report their average weekly participation in vigorous activities, such as hiking, jogging, bicycling, swimming, tennis, squash and rowing, or non-vigorous activities; during the 14 years of the follow-up study, a total of 2,890 men were diagnosed with prostate cancer, including 480 advanced cases.
