Hour of walking cuts breast cancer risk 14%

Women who walk for an hour a day can cut their chance of breast cancer by 14%, a study has found.

While it is well known that being active cuts risk of the disease, this is the first study to specifically look at the effect of walking.

The American Cancer Society study involved 73,615 post-menopausal women, of whom 4,760 were diagnosed with breast cancer during a 17-year follow-up.
