A clear, direct link between obesity and colorectal cancer has been shown in a new analysis. The report shows that obese individuals have a 20% greater risk of developing colorectal cancer compared with those of normal weight. The analyses also indicated that obese men are at 30% greater risk of developing the cancer compared with obese women. Findings from the study also showed that carrying even a few excess kilos substantially increases the risk of colorectal cancer; for every 5 kg weight gain the risk of developing the cancer increases by 7%.
