The risk of bowel cancer for overweight or obese people may have been underestimated, according to international researchers, who say that their study shows a higher risk of cancer the longer a person is overweight. The study included 5,635 individuals with bowel cancer and 4,515 people serving as controls and found that the risk of cancer as a result of excess weight was higher when calculated using the person's weight over their lifetime, rather than their weight at any single point in time. The researchers emphasise the importance of assessing risk based on lifetime factors, rather than information from any one point in time.
