Beer, bugs, DNA linked to stomach cancer

Genetic variant, low-grade infection and guzzling can add up to trouble

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.
