Summary
More than 22,000 people were analyzed in a study that found each additional 14 grams of alcohol a day—about one standard drink—was tied to a 10% higher colorectal cancer risk.
The elevated risk appeared across all major molecular subtypes examined, including MSI, CIMP, and tumors with BRAF or KRAS mutations, suggesting alcohol does not target just one biological pathway.
People consuming more than 28 grams a day—roughly two drinks or more—showed the clearest increase, strengthening evidence that heavier drinking carries greater danger.
The findings, published in the American Journal of Clinical Nutrition, back existing cancer-prevention guidance from AICR and related groups that the best option is to avoid alcohol or keep intake as low as possible.
