Studies regarding the benefits of exercise suggest that everyone would benefit from increased physical activity. However, it appears that about 30 minutes of daily exercise could significantly reduce risk of developing breast cancer for most women.
This is especially important since the American Cancer Society has documented that at least one in every eight women in the United States will develop breast cancer. On the other side, a new study out of Oxford University suggests that physical activity could greatly lower that risk in post-menopausal women.
“We’ve known for some time that exercise may help to reduce breast cancer risk after the menopause,” explains study author Tim Key. “But what’s really interesting about this study is that this does not appear to be solely due to the most active women being slimmer, suggesting that there may be some more direct benefits of exercise for women of all sizes.”
Key is a Cancer Research UK scientist with the cancer epidemiology unit at Oxford University. He continues:
“We don’t yet know exactly how physical activity reduces risk…but some small studies suggest that it could be linked to the impact on hormone levels in the body. “
To get a better idea, though, researchers observed more than 125,000 postmenopausal women. They studied body fat percentage—a key component to health status—as well what each woman self-reported regarding her physical activity. In general, 1,100 women in the study developed breast cancer at some point during the three-year study. However, researchers also found that women with higher average body fat had a 50 percent greater risk for developing breast cancer than women with lower body fat average.
What’s more studies suggest that regardless of body fat, 15-35 minutes of vigorous physical exercise can reduce breast cancer risk by 20 percent.
