Doctor advice The incidence of gastric cancer in our country remains high, with 400,000 new patients each year. Any Yulon, head of the First Affiliated Hospital of Sun Yat-sen University and center of cancer diagnosis and treatment at Sun Yat-sen University, said that in recent years, there has been a high incidence of digestive cancer, which is related to bad lifestyles, such as preference for smoked food, high salt, pickled foods, addiction to tobacco and alcohol , will destroy the normal function of the gastrointestinal tract, serious damage to the gastric mucosa, leading to gastritis, gastric ulcer and other diseases, increase the probability of suffering from gastric cancer. Eat pickles and fish sauce easily induce gastric cancer Now people's living conditions are good, but many bad eating habits are still difficult to change, such as heavy taste, love to eat pickled foods. Residents of Changle City, southern China, are accustomed to marinating seafood, and they particularly like fish sauce, shrimp paste and other condiments. This place is the country's "well-known" area of ​​high incidence of gastric cancer. In addition, Zhuanghe City, Liaoning Province, Linyi County, Shandong Province, Zanhuang County, Hebei Province and other residents have a dietary habit --- long-term consumption of salted pork. He Yulong reminded that because salt is contained in preserved foods, it will directly damage the gastric mucosa, and the nitrite contained in it will turn into nitrosamines under the action of stomach acid and bacteria, which is more likely to cause gastric cancer. Stomach and stomach cancer, confusing symptoms Gastric cancer has always been difficult to detect early, mainly because there are no discomforts in more than 70% of patients with early gastric cancer. Even if there are some symptoms, such as stomach pain, nausea, vomiting, etc., will also be considered stomach, it is rarely thought about stomach cancer, usually buy some stomach medicine, and will not go to the hospital. In this way, most patients have advanced gastric cancer when other symptoms are serious and they go to hospital. How to identify the alarm signal of stomach disease from their own feelings and symptoms? Experts said that the following points are worthy of attention--- (1) Abdominal pain loses the regularity of the onset of ulcers, which is obviously different from usual. (2) After the onset of stomach pain, eating or taking medicine will not help but increase. (3) In the past, appetite, body weight, and physical strength did not have much impact on the onset of stomach problems. Now, there is appetite loss, fatigue, and significant weight loss. (4) Unexplained anemia or persistent spasms. Above the gastrointestinal symptoms, to rule out gastric cancer, it is best to do gastroscopy. He said that gastroscopy is the most important means for diagnosing gastric cancer, not only to observe whether there is a lesion, but also to take 2-3 mm of gastric mucosa for biopsy to confirm the diagnosis. Fear of gastroscopy, the early detection rate was only 7% According to statistics, there are more than 400,000 new cases of gastric cancer in China every year. The mortality rate of gastric cancer is high, and the 5-year survival rate is only 37%. In other words, with stomach cancer, more than 60% of patients have not lived for 5 years. Director Ho said that this is mainly because many patients find gastric cancer, most of them are late, and the detection rate of early gastric cancer is only 7%. In Japan and South Korea, which are also areas of high incidence of gastric cancer, due to the census of gastric cancer is very effective, its early detection rate can reach 50%-60%. Take Japan as an example, they use double contrast and gastroscopy Screening, the number of people in the census every year in the past 10 years is between 3 million and 5 million, and 3000 to 6000 cases of gastric cancer are found each year, among which early gastric cancer accounts for more than 50%. Due to economic reasons (about 300 yuan for common gastroscopes, more expensive gastroscopes) and the public's fear of doing gastroscopy, early detection of gastric cancer has become a problem. In fact, using a bit of anesthetic before gastroscopy does not cause much pain, and the examination can be completed in about ten minutes. As with all tumors, early detection is naturally less tricky to treat. Director He said that the 5-year survival rate of early gastric cancer can reach more than 90%. Therefore, it is recommended that high-risk groups be able to do gastroscopy to screen for early gastric cancer. Tips: Who should pay attention to stomach cancer? 1. People over 40 years old. In theory, people over the age of 40 are high-incidence tumors; 2. People with gastric ulcer and history of duodenal ulcer; 3, the irrational diet structure, long-term pickled foods, like fish sauce, shrimp sauce and other condiments and other people.
