People with higher body mass index (BMI) have a greater rise in colon cancer rates compared to rectal cancer rates, suggesting that excess body fat may affect colon tumors more than rectal tumors.

Asian adults with a BMI above 30 have a 32% higher chance of developing colorectal cancer than those with a BMI between 23.0 and 25.0, based on long-term population data.

People with obesity have a higher chance of developing colorectal cancer compared to those without obesity, with men showing a greater increase in risk than women.

Adults with obesity have a higher likelihood of developing colorectal cancer compared to those without obesity, based on data from millions of people across multiple studies.

People who have been overweight or obese for many years have a higher risk of developing colorectal cancer than those whose weight changed recently, with the highest risk linked to weight measured 8 to 12 years before diagnosis.

People who had a high body mass index (BMI) 8 to 12 years before being diagnosed with colorectal cancer were more than twice as likely to develop the disease compared to those with a normal BMI, suggesting that carrying excess weight over a long period increases risk, even if weight drops shortly before diagnosis.
