A new report estimates that 40 percent of all cancer cases are associated with factors we can change—alcohol consumption being a prominent one.

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 percent 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.
