Preventing Cancer by Reducing Excessive Alcohol Use

Stop alcohol-related cancer

Excessive alcohol use is associated with many health and social problems, including cancer.

More than half of adults in the United States drink alcohol.1 Alcohol use increases the risk of cancers of the female breast, liver, colon, rectum, mouth, pharynx, larynx, and esophagus.2,3,4 There are evidence-based community strategies5 and clinical strategies6 that work to reduce excessive alcohol use.

Cancer Risks Linked with Alcohol Use

Excessive alcohol use is associated with many health and social problems. Alcohol is a carcinogen (something that can cause cancer).2,3,4 Regardless of drink type (beer, wine, or liquor), the risk of cancer increases with the number of drinks consumed, and even one drink a day increases the risk of developing cancers of the female breast, mouth, and esophagus.3 Reducing alcohol use may reduce the risk of cancer.7

How Is Alcohol Use Defined?

Moderate alcohol use is defined as consuming up to one drink per day for women and up to two drinks per day for men.

Excessive alcohol use includes binge drinking, heavy drinking, any alcohol use by individuals under the age of 21 years (minimum legal drinking age), and any alcohol use by pregnant women.

Binge drinking is a pattern of alcohol use that brings blood alcohol concentration levels to 0.08% or more. This is usually defined as consuming four drinks or more for women and five drinks or more for men on a single occasion, generally within about two hours.

Heavy drinking is defined as consuming eight drinks or more per week for women and 15 drinks or more per week for men.

The same amount of alcohol is contained in 12 fluid ounces of regular beer (5% alcohol), 8 ounces of malt liquor (7% alcohol), 5 ounces of wine (12% alcohol), and a 1.5-ounce shot of 80-proof distilled spirits (liquor such as vodka, whiskey, gin, or rum). All of these are considered a standard drink in the United States. Source: National Institute for Alcohol Abuse and Alcoholism.
What Are the Guidelines for Alcohol Use?

According to the Dietary Guidelines for Americans,8

  • If you choose to drink, do so in moderation—up to one drink a day for women or up to two drinks a day for men.
  • Don’t drink at all if you are younger than age 21, pregnant or may be pregnant, have health problems that could be made worse by drinking, or are engaging in activities for which alcohol is dangerous (like driving).
  • The Guidelines also do not recommend that you start drinking for any reason. Even moderate intake is associated with increased risks, including some cancers.
