The Claim

Men with obesity have a 57% higher risk of colorectal cancer compared to men with normal weight, and women with obesity have a 25% higher risk of colorectal cancer compared to women with normal weight, based on pooled hazard ratios from 66 observational studies.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Adult men with obesity are more likely to develop colorectal cancer than men with normal weight, and adult women with obesity are also more likely to develop colorectal cancer than women with normal weight, according to data from multiple population studies.

See the scientific wording

Men with obesity have a 57% higher risk of colorectal cancer compared to men with normal weight, while women with obesity have a 25% higher risk, based on pooled hazard ratios of 1.57 (95% CI: 1.38–1.78) and 1.25 (95% CI: 1.14–1.38) respectively from 66 observational studies.

What the research says

1 study

  1. Study: Overweight and obesity significantly increase colorectal cancer risk: a meta-analysis of 66 studies revealing a 25–57% elevation in risk

    This study found that men who are obese are 57% more likely to get colon cancer than men at a normal weight, and women who are obese are 25% more likely — just like the claim says.
