First of all, not all patients with gastric ulcer will become cancerous, and patients who have suffered from gastric ulcer disease for ten years or decades will not necessarily develop malignant lesions. According to clinical data, less than 5% of ulcers have malignant lesions, but mostly occur in older patients, those with longer duration of disease, those who have not undergone standardized treatment, and those with bad habits, such as smoking and drinking, and those with irregular life and bad eating habits. Therefore, after suffering from gastric ulcer, you must develop good living and eating habits, quit smoking and drinking, do not eat spicy and stimulating food, choose soft, easily digestible and nutritious food, which can well prevent gastric ulcer malignant lesions.
