Fifteen minutes of vigorous exercise every day could cut the risk of breast cancer by one fifth, Oxford University research has found. The study of 125,000 post-menopausal women found that those who did the most physical activity had a far lower chance of developing the disease than those who did the least exercise. Women who did between 15 minutes and 35 minutes of vigorous exercise, such as running, every day were one fifth less likely to develop breast cancer, compared with those who took no vigorous exercise.
The study also found that women with the most body fat were 55 per cent more likely to develop the disease than the leanest women. But being physically active helped reduce the risk of breast cancer regardless of a woman’s weight.
