Walking an hour a day reduces breast cancer risk

Women who do moderate exercise-such as walking an hour every day-reduce their risk of developing breast cancer after the menopause.
Exercise reduces the risk by around 14 per cent among women who do moderate exercise, and reduces further-to 25 per cent-in women who carry out more vigorous activities.
The protective effect is seen in women who take a steady stroll, a speed of around 3 mph, for seven hours a week, compared to women who exercise less or not at all.
Researchers at the American Cancer Society made the discovery after they analysed the lifestyles of 73,615 post-menopausal women. During the 17-year study, 4,760 women developed breast cancer, but those who exercised seemed to reduce their risk.
