About 10,000 cases of breast and bowel cancer could be prevented each year in the UK if people did more brisk walking, claim experts.
The World Cancer Research Fund scientists say any moderate activity that makes the heart beat faster should achieve the same. For example, data suggest 45 minutes a day of moderate exercise could prevent about 5,500 cases of breast cancer. Physical exercise helps prevent obesity, which is a cancer risk factor.
The WCRF team stress in their report that it is the total time spent being active that is important. You do not need to set aside half an hour each day to exercise. Shorter bouts of activity will be just as beneficial as long as they add up to the same, the charity says.Alongside brisk walking, other activities that would count include cycling or swimming at a leisurely pace, dancing, gardening and vacuuming combined with other housework, says the WCRF.
