First seen Feb 25, 2026 · Last updated Jun 22, 2026 · Updated 21 times
Summary
This study follows 3,000 adults aged 40 and older who carry Helicobacter pylori, a common stomach bug. Researchers want to see if people with certain high-risk subtypes of the bacteria develop stomach cancer more often than those with other subtypes or no infection. Participants will have regular check-ups and stomach exams over 3 to 10 years. No treatment is given—this is purely an observation to better understand cancer risk.
