Gastric ulcers can be categorized into benign ulcers and malignant ulcers, in which benign ulcers do not affect the survival time, and malignant ulcers, i.e. gastric cancer, early gastric cancer can be cured, and the five-year survival rate of intermediate and advanced gastric cancer is about 7% to 34%. 1. Benign ulcers, i.e. peptic ulcers, are inflammatory defects in the mucosa of the gastrointestinal tract, which are usually associated with excessive secretion of gastric acid or damage to the mucosal barrier of the gastrointestinal tract. As a common disease, peptic ulcer can be treated with oral proton pump inhibitors such as omeprazole and gastric mucosal protectors such as bismuth potassium citrate and aluminum thioglycollate under the guidance of doctors, which will not affect the survival of patients after standardized internal medicine treatment. 2. Malignant ulcer, i.e. gastric cancer, is a malignant tumor originated from epithelial cells of gastric mucosa, which may be related to Helicobacter pylori infection, diet, heredity, pre-cancerous lesions and other reasons. Early gastric cancer, if detected early and treated with surgery, usually does not affect the patient’s life span. As stomach cancer is often asymptomatic in the early stage and is usually detected late, the five-year survival rate of patients with intermediate and advanced stomach cancer is usually 7% to 34%, which has a greater impact on the survival time of patients. Patients with gastric ulcers should go to the hospital in time to identify the nature of the ulcers by means of gastroscopy and other examinations, and receive timely symptomatic treatment to improve the prognosis.
