Tobacco Smoking Increases the Risk for Gastric Adenocarcinoma among Helicobacter pylori-infected Individuals

Abstract

Tobacco smoking and H. pylori are both risk factors in the development of gastric cancer, and tobacco smoking is still a risk factor among H. pylori-infected individuals. The risk of gastric cancer among H. pylori-infected current smokers is 11 times that of non-infected individuals not currently smoking.
