  • Yet another modern example of dogma-defying research is provided by recent studies proving that bacteria (Helicobacter pylori) are a common cause of stomach ulcers, which can eventually lead to stomach cancer and lymphoma. (whale.to)
  • For a century, physicians refused to believe that bacteria could cause ulcers because they thought bacteria could not live in the acid environment of the stomach. (whale.to)
  • In 1982 a researcher, who was unable to convince his colleagues that bacteria could cause ulcers and gastritis, actually proved his case by drinking a culture of H. pylori. (whale.to)
