This trial is testing whether a stool test that looks for specific genetic markers related to Helicobacter pylori (a common stomach bacteria) can help identify people at high risk for stomach cancer before symptoms appear. Researchers will collect stool samples from 10,000 to 15,000 adults and combine the test results with answers to health questions to find people who need further screening. Anyone who tests positive will be offered a camera procedure (endoscopy) with a biopsy to check for early signs of cancer.
Stomach cancer is often found late when it's harder to treat, but catching it early can save lives. This trial hopes that a simple, non-invasive stool test could help doctors identify at-risk people before cancer develops, making screening easier and more accessible than current methods.

If you join, you'll be asked to provide a stool sample and complete a health questionnaire during a face-to-face interview with a trained staff member. If your stool test or questionnaire results suggest higher risk, you'll be referred for an endoscopy (a gentle camera procedure with a small tissue sample). People who don't have cancer in the first year will then be invited back for follow-up visits once a year to monitor their health. Leftover samples will be stored for future research to better understand gastric cancer risk.
