Women Who Exercise Regularly Have Lower Risk of Breast Cancer
From Times staff and wire reports
A new study in the May 1 New England Journal of Medicine provides some of the strongest evidence yet that regular exercise helps protect women from breast cancer. The research, conducted in Norway, found that women who exercise at least four hours a week have about a one-third lower than usual risk of breast cancer.
Whether exercise truly prevents breast cancer, though, is less clear, and the latest study is unlikely to persuade all skeptics. Women who work out a lot also usually have other healthy habits, so it’s difficult to say whether it is exercise that wards off cancer. But at least a dozen studies have now found a link between exercise and less breast cancer.
