Stem cells carry proto-oncogenes/tumor-suppressor genes; normally silent. Family history = easier oncogene expression (genetic). External carcinogens: direct induction or chronic mucosal barrier damage → oncogene expression/gene mutation → immature cells don't differentiate → uncontrolled growth. Normal immune surveillance clears abnormal cells; chronic stress/immunodeficiency/immune escape → gastric cancer.
