Study shows that regular exercise reduces prostate cancer mortality. Nearly 16 million men worldwide suffer from prostate cancer, and the results of the study will help these men adopt the right lifestyle to improve their survival period. Researchers evaluated the impact of physical activity on more than 2,700 men with prostate cancer between 1990 and 2008, and reported that patients who continued to exercise were less likely to die from cancer or other causes. Men who exercised for at least three hours a week had a 61 percent lower risk of death from prostate cancer compared with men who engaged in less than one hour of vigorous activity per day, and men who exercised vigorously before and after their cancer diagnosis had the lowest risk of death. The study authors concluded that exercise reduces cancer mortality and incidence in men overall, and that moderate amounts of vigorous exercise such as cycling, tennis, jogging or swimming for at least three hours per week can significantly improve prostate cancer-specific survival periods. Studies have shown that increased daily physical activity can reduce the risk of disease progression in men with prostate cancer,” said study lead author Stacey Kenfield, PhD, of the Harvard School of Public Health. We have observed that patients can benefit from moderate amounts of exercise, and our study also shows that exercise benefits the overall health of prostate cancer patients, even in small amounts such as walking 15 minutes a day, jogging, cycling or gardening. However, three or more hours of vigorous exercise per week for patients with prostate cancer would be particularly beneficial for their cancer resistance and overall health.
