Alcohol consumption is likely to increase during the holiday season, but a new study contains old reminders about the risks. Researchers at Florida Atlantic University College of Medicine reviewed more than sixty studies that confirm both how much and how often alcohol is consumed significantly influences risk of cancer, especially breast, colorectal, liver and oral cancers. Conditions such as obesity and chronic liver disease further heighten the risk. Other variables, such as smoking, type of alcohol and genetics also play a role. Authors of the study in the journal Cancer Epidemiology note higher alcohol consumption was linked to the highest risk, but even moderate drinking may increase the risk. Something to reflect on before raising a glass or two in celebration.
