Alcohol and Cancer

Drinking alcohol raises the risk of some cancers. Drinking any kind of alcohol can contribute to cancers of the mouth and throat, larynx (voice box), esophagus, colon and rectum, liver, and breast (in women). The less alcohol you drink, the lower the risk of cancer.

The less alcohol you drink, the lower your risk for cancer.

Drinking alcohol raises your risk of getting six kinds of cancer—

  • Mouth and throat.
  • Voice box (larynx).
  • Esophagus.
  • Colon and rectum.
  • Liver.
  • Breast (in women).

All types of alcoholic drinks, including red and white wine, beer, cocktails, and liquor, are linked with cancer. The more you drink, the higher your cancer risk.

What Are the Guidelines for Alcohol Use?

The Dietary Guidelines for Americans, 2015–2020,External recommend that if you drink alcohol at all, drink in moderation—no more than one drink a day for women, and no more than two drinks a day for men. If you don’t drink, don’t start drinking because of any possible health benefits.

Don’t drink at all if you—

  • Are under the legal drinking age.
  • Are pregnant or may be pregnant.
  • Have health problems that could be made worse by drinking.
  • Are doing things like driving that could be dangerous with alcohol.

It’s safest not to drink if you are on any medication, including cancer treatment.External If you’re taking prescription medicine, ask your doctor if it’s safe before drinking alcohol.

Why Does Alcohol Use Raise Cancer Risk?

When you drink alcohol, your body breaks it down into a chemical called acetaldehyde. Acetaldehyde damages your DNA and prevents your body from repairing the damage. DNA is the cell’s “instruction manual” that controls a cell’s normal growth and function. When DNA is damaged, a cell can begin growing out of control and create a cancer tumor.
