In the latest analysis, the researchers dug deeper into the relationships between the amount of physical activity and how much lower the cancer risk became. Recommended levels of physical activity showed what could be a range of potential benefits, from a 6-10% lower risk of breast cancer to an 18-27% lower risk of liver cancer. "There is substantial evidence that higher levels of physical activity are linked to lower risks of several cancers," explains the National Cancer Institute . "These other differences, rather than the differences in physical activity, could explain their different cancer risk," according to the institute. A number of other factors have been linked to cancer risk, including smoking, diet and obesity.
