Drinking alcohol may be related to cancer, study finds, but there are many unknowns
CNN
Over 4% of all new cancer cases in 2020 were attributable to alcohol consumption, a new study has found. Several other potentially influential factors could weaken the strength of that proposed relationship.
The researchers analyzed available data on population-level alcohol use in 2010 and on cancer cases in 2020. They assumed a 10-year period between alcohol consumption and the appearance of cancer, since the types of cancer included in the study -- lip and oral cavity cancer, laryngeal cancer and breast cancer (among females) -- have lengthy development periods and previous evidence of a causal relationship with alcohol consumption. Of the 741,300 new alcohol-attributable cancer diagnosed last year, men represented 568,700 cases, while women accounted for 172,600 cases, the researchers found. Most of these cancers were in the esophagus, liver and breasts. Nearly 47% of the alcohol-attributable cancers were linked to heavy drinking, which the authors defined as 60 or more grams of ethanol alcohol (the alcohol found in alcoholic beverages), or more than six drinks, per day.More Related News
