Finding of stomach cancer early

When stomach cancer is detected and treated early, the chances of successful treatment are better. Recognizing symptoms and getting regular checkups are the best ways to detect stomach cancer early. The sooner symptoms are reported, the sooner a doctor can diagnose and treat the cancer.

High-risk individuals

People who are at higher than average risk of developing stomach cancer may need to be tested more often than people with average risk. Examples of what puts a person at higher than average risk include:

  • having a higher than average risk of Helicobacter pylori (H. pylori) infection
    • People with a first-degree relative diagnosed with stomach cancer may have a higher risk for infection.
    • Some ethnic and geographical groups have a high risk of stomach cancer related to H. pylori infection.
  • rare inherited conditions
    • hereditary diffuse stomach cancer
    • familial adenomatous polyposis (FAP)
    • hereditary non-polyposis colorectal cancer (HNPCC)
    • Peutz-Jeghers syndrome
    • Li-Fraumeni syndrome
    • BRCA gene mutations
  • certain stomach problems
    • stomach polyps
    • chronic atrophic gastritis
    • gastric epithelial dysplasia
    • intestinal metaplasia
    • Menetrier disease
    • pernicious anemia
  • previous stomach surgery


People who are at higher than average risk should talk to their doctor about a personal plan for testing. A personal plan of testing may include:
