ORLANDO, Fla. — Swilling at least three beers a day over several years can increase a person’s risk of stomach cancer if combined with two other unseen risk factors, researchers have found. But oddly, wine and liquor didn’t show the same danger level for this malignancy, the team reported April 4 at a meeting of the American Association for Cancer Research.
The triple threat includes carrying two copies of rs1230025, a gene variant located amid a cluster of genes associated with degrading alcohol in the body. The third risk factor is an infection with Helicobacter pylori, a well-known bacterium that causes stomach cancer and ulcers. H. pylori infection is uncommon in the United States, but roughly half the world’s population carries the microbe.
