Superficial gastritis is a type of chronic gastritis and is generally not cancerous, but the details vary from person to person. Chronic gastritis can be divided into non-atrophic gastritis and atrophic gastritis, and non-atrophic gastritis is superficial gastritis. There is a close relationship between gastric cancer and atrophic gastritis, while non-atrophic gastritis is generally not cancerous. However, it should be noted that non-atrophic gastritis tends to recur for a long time and may change to atrophic gastritis. Further development of atrophic gastritis may result in enterosis and heterogeneous hyperplasia, with a significantly higher risk of cancer, but the transformation process is lengthy, usually taking several years to a decade. However, not everyone will necessarily change from superficial gastritis to atrophic gastritis or even cancer. You should maintain a good diet and hygiene habits, quit smoking and drinking, pay attention to the work and rest routine, adhere to physical exercise, and enhance your immunity. Once superficial gastritis occurs, it should be actively treated formally.
