H pylori is a gram-negative bacterium responsible for approximately 90% of non-cardia gastric cancers, according to Morgan and colleagues. In 1994, the World Health Organization International Agency for Research on Cancer classified H Pylori as a type I carcinogen; H pylori is a known risk factor associated with the development of gastric cancer, as well as atrophic gastritis and gastric lymphoma. Epidemiologic studies suggest a sixfold increase in the risk for gastric cancer among individuals infected with H pylori compared with individuals without infection.

EBV has been shown to be associated with approximately 5%-10% of gastric carcinomas diagnoses.

Numerous studies suggest a higher risk for gastric cancer among individuals with blood group type A.
