Doctors flag cancer risk from persistent gastric problems

Doctors warn that persistent gastric problems, often dismissed as acidity or indigestion, can signal changes in the stomach lining that increase the risk of cancer. Prolonged inflammation, especially due to Helicobacter pylori (H pylori) infection, can cause precancerous changes. According to 2025 estimates, Karnataka recorded 4,432 new stomach cancer cases, with Bengaluru's Population-Based Cancer Registry recording 767 cases.
