A little bit of alcohol was once thought to be good for you. However, as scientific research advances, we're gaining a clearer picture of alcohol's effect on health—especially regarding cancer. The complex relationship between alcohol and cancer was recently highlighted in a new report from the American Association for Cancer Research.
The report's findings are eye-opening. The authors of the report estimate that 40% of all cancer cases are associated with " modifiable risk factors "—in other words, things we can change ourselves. Alcohol consumption being prominent among them.
Six types of cancer are linked to alcohol consumption : head and neck cancers, esophageal cancer, liver cancer , breast cancer , colorectal cancer and stomach cancer. The statistics are sobering. In 2019, more than one in 20 cancer diagnoses in the west were attributed to alcohol consumption, and this is increasing with time.
This figure challenges the widespread perception of alcohol as a harmless social lubricant and builds on several well-conducted studies linking alcohol consumption to cancer risk . But this isn't just about the present—it's also about the future. The report highlights a concerning trend: rising rates of certain cancers among younger adults.
It's a plot twist that researchers like me are still trying to understand, but alcohol consumption is emerging as a potential frontrunner in the list of causes. Of particular concern is the rising incidence of early-onset colorectal cance.
