There is no such thing as a “few months” between a stomach ulcer and cancer. Whether gastric ulcers will become cancerous and how long it will take to become cancerous are related to the course of the disease, concomitant lesions, age, life habits and other factors. 1. Disease duration: clinically, if the disease duration is recurrent and prolonged, the risk of cancer is relatively high. 2. Accompanying lesions: if the ulcer is accompanied by other lesions such as moderate atrophic gastritis, intestinal epithelial hyperplasia and atypical hyperplasia, etc., there is a certain risk of cancer. 3. Age: the risk of cancer is higher in older patients compared with younger patients. Research shows that the risk of ulcer cancer is relatively higher in elderly patients due to the decline of gastric mucous membrane barrier protection function and other factors. 4. Lifestyle habits: Many bad lifestyle habits can also affect the chance of cancer. Gastric ulcer cancer risk is related to smoking, diet, irregular life, psychosocial factors, irregular treatment and other factors. If gastric ulcer is diagnosed, early and standardized treatment is recommended to reduce the adverse effects of the disease.
