The study analyzes the global burden of cancer in 2020 attributable to alcohol consumption. Using data from the GLOBOCAN 2020 database and alcohol consumption patterns, it estimates that 4.1% of all new cancer cases globally (approximately 741,300 cases) were caused by alcohol. The most affected cancers include esophageal, liver, and breast cancer, with heavy drinking contributing the most cases, followed by risky and moderate drinking. The study highlights regional differences, with the highest attributable fractions in Eastern Asia and Central and Eastern Europe. It underscores the need for policies to raise awareness about alcohol-related cancer risks and reduce alcohol consumption globally.
