New global analysis confirms alcohol’s cancer risk even at low levels

07.06.2026 - A new global analysis from the Institute for Health Metrics and Evaluation (IHME) at the University of Washington confirms that alcohol use is associated with increased risk for all ten cancers examined in the study. The study, published in Nature Health on June 1, 2026, applied IHME’s Burden of Proof framework to 843 cohort and case-control studies published through 2023.

The cancer findings are clear. Risk increased as alcohol consumption rose, but the study also found elevated risk even below one standard drink per day, defined as less than 10 grams of pure alcohol. This low level of consumption was associated with increased risk for cancers of the pharynx, colorectum, esophagus, breast, liver, pancreas, and prostate.

The strongest evidence of harm was found for pharyngeal cancer, excluding nasopharyngeal cancer, where the analysis showed at least a 105% increase in risk at average consumption levels. Moderate evidence of harm was also found for cancers of the larynx, colorectum, and lip and oral cavity, with risk increases of at least 22% to 49%. Esophageal, breast, liver, pancreatic, and prostate cancers showed weaker but consistent evidence of harm, with risks rising steadily as consumption increased.

The findings also have implications for alcohol guidelines. According to the authors, the evidence does not support one universal “safe” threshold for alcohol consumption. They argue that drinking guidelines should reflect the full range of health outcomes, discourage heavy episodic drinking, and clearly communicate that even low-to-moderate alcohol intake is associated with increased risk for several conditions, especially cancers.

Public awareness of alcohol’s link to cancer remains relatively low, especially for cancers that are less often discussed in this context, such as breast and colorectal cancer. The study adds further support for clear public health guidance that helps people understand the cancer risks connected with alcohol and make informed decisions about drinking.
