Reduce breast cancer risk with exercise.


This study investigated the relationship between recreational physical activity (RPA) and breast cancer risk in a population-based sample of 1504 cases (n = 233 in situ, n = 1271 invasive) and 1555 controls from the Long Island Breast Cancer Study Project, in Long Island, New York. The results showed 10-19 hours per week of RPA at any intensity level during the reproductive and postmenopausal years has the greatest benefit for reducing breast cancer risk. However, substantial postmenopausal weight gain may eliminate the benefits of regular activity. The authors conclude "Collectively, these results suggest that women can still reduce their breast cancer risk later in life by maintaining their weight and engaging in moderate amounts of activity".


Note: 10-19 hours a week had the greatest benefit...we need to get out and play more!
