Alcohol Consumption and Lung Cancer According to Ile349Val Polymorphism in ADH3 Gene: Beyond the Tobacco Smoking Effect

Alcohol consumption at levels equal to or greater than 30 grams per day may facilitate the development of lung cancer independent of smoking status.

​This study examined whether alcohol intake favors the development of lung cancer. Researchers assessed the alcohol drinking habits of 402 patients with lung cancer and 383 healthy persons. 

Researchers noted that ingestion of 30 or more grams of alcohol per day heightened the risk of lung cancer irrespective of smoking status. "This study suggests that beyond smoking consumption, a high consumption of alcohol might increase the risk of lung cancer," the authors concluded.
