Stomach cancer has always been a highly prevalent cancer in China. The incidence rate of gastric cancer in China accounts for 42% of the world, and the incidence rate of gastric cancer among young people aged 19 to 35 has doubled in the past 5 years compared to 30 years ago. Although the incidence of stomach cancer is trending younger, many young people are not aware of it. In addition to genetic factors, young people suffer from gastric cancer mainly due to bad habits such as staying up late for a long time, irregular diet and high mental stress. Some young people not only drink and smoke, but also like to eat barbecue and pickled food, and have spicy and salty taste. In the long run, gastritis, gastric ulcer and other gastric diseases will easily find their way to the door and increase the risk of gastric cancer. In addition, most young patients are reluctant to have gastroscopy, resulting in low detection rate of early gastric cancer. Gastric cancer is well hidden and easy to be ignored Studies show that after early detection of gastric cancer, the 5-year survival rate of patients without lymph node metastasis is about 90% or even higher. However, once lymph node metastasis occurs, the 5-year survival rate is only about 20% regardless of the treatment method. Therefore, early detection of gastric cancer is very crucial. However, stomach cancer is well hidden, and many patients with early stage stomach cancer do not feel discomfort, and even if they have symptoms, they think it is just a stomach disease. As long as they feel uncomfortable in the stomach, they should seek medical consultation in time. Studies have confirmed that people who have gastroscopy once a year have lower incidence of gastric cancer. Especially for patients with chronic gastritis and gastric ulcer, it is more important to pay attention to return visits on time. At present, there are three main means to confirm the early diagnosis of gastric cancer. One is H. pylori examination, which is closely related to the incidence of gastric cancer; the second is pepsinogen examination in blood, which is mainly to monitor the state of gastric mucosa; and the third is gastroscopy. For the examination, people between 35 and 40 years old can start to do gastroscopy once or twice. It is more important for people who have family history of cancer especially stomach cancer, love pickled food, irregular diet, and have long term gastric ulcer or gastritis. Another point is that the symptoms of gastric diseases are very similar, so it is important to make a clear diagnosis first before prescribing the right medicine. Blind medication not only tends to mask the symptoms, but also delays treatment. How to protect our stomach? 1, three meals should be regular, breakfast must be eaten.
