Alcohol consumption causally increases the risk of several human cancers.

The Claim

Alcohol consumption causes cancer in humans.

The Short Version

Alcohol is a well-established human carcinogen. Major public-health and cancer authorities state that drinking alcohol causally increases the risk of several cancers, including breast, colorectal, liver, esophageal, and head-and-neck cancers. The claim is broad, but the omitted nuance does not alter the central fact that alcohol consumption causes cancer in humans.

Caveats

  • This is probabilistic causation: alcohol increases cancer risk; it does not mean every drinker will develop cancer.
  • The strongest evidence is for several specific cancer types, not for every cancer indiscriminately.
  • Risk generally rises with greater consumption, and some risks are amplified by co-exposures such as tobacco.
