How many years does it take for gastric atrophic gastritis c2 to become cancerous?

Atrophic gastritis C2 may not necessarily become cancerous, and even if it does, the exact timing varies from person to person.
After the diagnosis of atrophic gastritis is clear, patients should take relevant treatment measures under the guidance of professional physicians, combining with the symptoms and signs of patients and auxiliary examinations to slow down the progression of the disease.
Clinical research shows that the chance of atrophic gastric cancer turning into cancer is 0.1%~1%, therefore, atrophic gastritis C2 may not necessarily become cancerous, and even if it does, the exact time varies from person to person. Therefore, regular monitoring should be paid attention to and gastroscopy is recommended once every 1~2 years for early detection and early intervention.
Once early cancer is detected in atrophic gastritis, it can be treated by means of endoscopic ESD or surgical resection.
Early gastric cancer has the possibility of cure, once it enters into middle or late stage and local or distant metastasis occurs, its eradication rate will be greatly reduced.
The above situations should be immediately sought for medical treatment and early intervention under the guidance of specialized physicians.
