The Claim
Higher levels of physical activity are associated with a 10% reduction in overall cancer risk and specific reductions of 20–25% for colorectal cancer and 15% for colonic adenomas, as observed in pooled analyses of over 1.4 million adults from prospective cohort studies.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who engage in more physical activity have a lower risk of developing cancer overall, with particularly lower risks for colorectal cancer and colonic adenomas, based on data from large long-term studies of over a million adults.

1 studyStudy: Physical activity, sedentary behaviour, diet, and cancer: an update and emerging new evidence
Being active is linked to lower cancer risk, especially for colon cancer, and this study confirms that people who move more tend to get less cancer.
