Alcohol Study of 843 Papers Finds Cancer Risk Rises Even Below 10 Grams a Day

A Burden of Proof review of 843 cohort and case-control studies found current drinking raised risk for multiple cancers, liver disease, pancreatitis, infections and atrial fibrillation, while high intake increased risk across all 20 outcomes examined.
The analysis of 16 systematic reviews found the strongest evidence for other pharyngeal cancer: average intake was linked to at least a 105% higher risk, and risk estimates reached 1.16 at 10 grams a day.
Five outcomes—including cirrhosis, pancreatitis, colorectal, laryngeal, and lip and oral cavity cancers—showed moderate harmful associations, while even low consumption under 10 grams a day was tied to elevated risk for nine cancers.
Some outcomes showed J- or U-shaped patterns, with low-to-moderate intake associated with lower observed risk for type 2 diabetes, dementia and some cardiovascular diseases, but the authors said those apparent benefits are observational, uncertain and not an endorsement to drink.
The study argues current evidence does not support a universal or sex-specific 'safe' threshold, suggesting guidelines should stress lower overall intake and clearer warnings about alcohol's carcinogenic effects.

No Safe Level: The 2026 IHME Review Finds Any Alcohol Increases Cancer Risk
Overview
A major review by the Institute for Health Metrics and Evaluation (IHME), published in June 2026, has changed how we understand alcohol and cancer. The study analyzed 843 studies and 20 health outcomes, showing that there is no safe level of alcohol when it comes to cancer risk. This finding challenges old beliefs and previous guidelines, marking a big shift in public health. The IHME review’s thorough approach gives a clearer picture of how even small amounts of alcohol can increase cancer risk, urging a rethinking of health advice and personal choices about drinking.
