Gene May Explain Why Some Have Higher Stomach Cancer Risk

Vital Information:

  • Researchers have found a genetic explanation for why people infected with H. pylori are at high risk for either stomach cancer or ulcers, but not both.
  • Some people have a gene that causes them to produce low levels of gastric acid, leaving the stomach less able to fight off toxins and the H. pylori infection, which can lead to cancer.
  • Others, who lack the gene, produce higher levels of gastric acid in the stomach, which kills off infection but may cause ulcer formation.
