Even small amounts of alcohol increase cancer risk, though some diseases may see reduced risk

Even minimal alcohol consumption, equivalent to one to two shots of soju or half a can of beer, significantly elevates the risk of developing major cancers and chronic liver diseases, according to a comprehensive meta-analysis. The study, published in Nature Health, analyzed 843 patient-control and cohort studies conducted up to 2023. Researchers from the University of Washington's Institute for Health Metrics and Evaluation (IHME) employed a 'Burden of Proof' framework to provide cautious risk estimates.

The analysis consistently found a link between alcohol consumption and cancer. All ten types of cancer examined showed an increasing risk trend with higher alcohol intake, even at levels below one drink per day (less than 10g of pure alcohol). This finding challenges the notion that very light drinking poses no significant health threat.

Conversely, the research also acknowledged observational findings suggesting potential benefits from light drinking. Some studies indicated a reduced risk for certain cardiovascular, metabolic, and neurological diseases among individuals who consume small amounts of alcohol. However, the study's methodology emphasizes the cancer risk, highlighting the need for careful consideration of the overall health implications.
