I believe we have all heard the phrase "disease comes from the mouth", the stomach as an organ in direct contact with food, first of all suffer from food spicy, greasy, cold stimulation, etc., the number of people suffering from stomach disease has been high, if the stomach disease is not in time, it may develop into stomach cancer. The occurrence of gastric cancer is not accidental, but the development process from inflammation to cancer, and if timely intervention is carried out in the early stage of gastric cancer, it may be possible to prevent the malignant development of the disease. （These 5 types of inflammation are the most likely to become cancerous, and symptoms should be dealt with in time! The pattern of gastric cancer progression is generally as follows:Normal gastric mucosa Chronic superficial gastritis Chronic atrophic gastritis Intestinal metaplasia Dysplasia Gastric cancer. 
This process is relatively long, and early detection, early intervention, and early blocking are the key pointsHere's a look at what happens before stomach cancer occurs5 signals1. Gastric ulcerGastric ulcer is a relatively common digestive disease, and the incidence will increase with age, at the age of 50-60, which is the highest age for the onset of gastric ulcer. There are many reasons for the occurrence of gastric ulcers, such as irregular diet, long-term alcohol consumption, overeating, etc. Gastric ulcer is one of the most common precancerous gastric diseases, with a 1%-5% chance of becoming cancerousThe longer the history of gastric ulcer disease, the higher the probability of cancer. 2. Chronic atrophic gastritisThe main ** gastric Helicobacter pylori infection in chronic atrophic gastritis, the main manifestations are:Discomfort, fullness, pain in the upper abdomenIt is also one of the precancerous diseases of the stomach, and the carcinogenesis rate will increase with age, and about 1 50% of patients with chronic atrophic gastritis will become gastric cancer within 20 years (for reference only). 
Network invasion and deletion).
3. Gastric polypsGastric polyps are generally asymptomatic and can occur when patients have other digestive disordersBloating, abdominal pain, indigestion, abdominal fullnessand other symptoms. The rate of carcinogenesis of gastric polyps is low, but if the gastric polyp is larger than 2 cm, the probability of carcinogenesis is 2%-4%, which is still something to be aware of. 4. Postoperative residual stomachResidual gastric cancer is also a type of gastric cancer, which is usually caused by malignant transformation of the remaining stomach after gastric cancer surgery. 5. Precancerous lesionsIn addition to the above 4 precancerous diseases that need attention, it is also necessary to pay attention to precancerous lesions, if you can pay attention to precancerous lesions, or you can stifle the occurrence of cancer in the cradle.
