How are alcohol and cancer linked?
Alcohol is classified as a Group 1 carcinogen, meaning it is known to cause cancer. After drinking alcohol, the body breaks it down into acetaldehyde, a chemical that damages your DNA and prevents your body from repairing that damage. With the DNA damaged, a cell can begin growing out of control and create a cancer tumor.
Because alcohol is a carcinogen, lower levels of drinking can also be harmful even if you don’t feel drunk.25
