The association between alcohol consumption and risk of gastric cancer remains controversial. Moreover, prospective data on the role of alcoholic beverage type are sparse. We prospectively investigated the association between total alcohol (ethanol) intake as well as specific alcoholic beverages and risk of gastric cancer in the Swedish Mammography Cohort, a population-based cohort of 61,433 women. ⋯ Consumption of medium-strong/strong beer was associated with a statistically significant increased risk of gastric cancer; the multivariate HR for women who consumed more than one serving of medium-strong/strong beer per week (median, 2.5 drinks/week) was 2.09 (95% CI, 1.11-3.93; p-trend = 0.02) compared with no consumption. Consumption of light beer, wine, and hard liquor was not significantly associated with gastric cancer risk. Our findings suggest that constituents of beer other than alcohol may be associated with an increased risk of gastric cancer.
