People with high risk of stomach cancer need gastroscopy more than the general population. 1.People with family history of tumor In two or three generations of relatives who have had digestive system tumor or other tumors, their chances of getting gastric cancer will be higher. 2.People with chronic gastric diseases such as gastric ulcer, chronic atrophic gastritis and Helicobacter pylori infection People with these diseases should be treated actively to prevent and control the disease progress and go to hospital for regular review. 3, people with long-term smoking, drinking alcohol, especially love to eat hot food, pickled and barbecued food, high salt food and other bad habits These habits can cause serious damage to the stomach and should be adjusted in a timely manner, and should not refuse the doctor’s recommendation for gastroscopy. It is recommended that a gastroscopy should be done once over the age of 45-50, and no positive findings or no high-risk factors for 3-5 years can usually be done without re-examination. Those who are found to have chronic atrophic gastritis with intestinal epithelial hyperplasia or heterogeneous hyperplasia and other risk factors for gastric cancer should be reviewed with the doctor’s recommendation. There are always people who find gastroscopy unpleasant, but don’t hesitate to have gastroscopy when it’s time to do so compared to the regret brought by avoidance.
