Most people think that stomach cancer is very scary and there is no cure once they have it. In fact, there are two types of gastric cancer: early stage gastric cancer and progressive stage gastric cancer (actually two stages). Regardless of the type of gastric cancer that can be surgically removed, standardized surgical treatment should be performed. However, radical resection of gastric cancer is still the only possible way to eradicate gastric cancer, and the 3-year survival rate of patients can reach more than 50%. Therefore, stomach cancer is not scary, but the key lies in early detection and early treatment. How to detect it early? Routinely, as long as there is hidden pain and discomfort in the upper abdomen, early gastroscopy is the most direct and reliable examination method. For those who have chronic gastritis or ulcer, it is also necessary to review gastroscopy regularly.
