Generally speaking, chronic non-atrophic gastritis with erosion biopsy will not be gastric cancer, but if it is prolonged for a long time, it may develop into gastric cancer. Biopsy of chronic non-atrophic gastritis can clarify the nature of lesions. Generally speaking, gastritis with erosion indicates inflammatory lesions, which will not develop into cancer if treated in time. It is recommended to take medication according to medical advice, such as omeprazole, lansoprazole, magnesium aluminum carbonate and so on.
