Alcohol-Related Cancers
- Alcohol is the third leading preventable cause of cancer in the US, after tobacco and obesity.
- It's linked to seven cancers: breast, colorectal, mouth, throat, voice box, esophageal, and liver.
How Alcohol Causes Cancer
- Alcohol breaks down into acetaldehyde, a toxic substance that damages DNA and increases cancer risk.
- It also induces oxidative stress, alters hormone levels (like estrogen), and increases absorption of other carcinogens.
Minimizing Cancer Risk
- There's no magic number for safe alcohol consumption; lower consumption means lower cancer risk.
- If you drink occasionally, your risk is less than if you drink daily.
