Gastric cancer is the most common malignant tumor in China. In today’s increasingly developing society, its incidence rate is the highest among all kinds of tumors, and tens of thousands of patients die of gastric cancer every year, which shows how harmful it is, and early prevention is of great significance. There are many factors that trigger stomach cancer, but a large part of patients have got this disease because of their normal living habits. What are the ways to prevent stomach cancer? In daily life, we should pay attention to the following six aspects of prevention: 1. To develop good eating habits The life span of gastric mucosal epithelial cells is very short, and they need to regenerate once every 2 to 3 days, and this regeneration process usually takes place at night when the gastrointestinal tract is resting. If you often eat at night, the gastric mucosa will not be repaired in time, which will increase the risk of gastric cancer in the long run. So try not to eat late at night as often as possible. The risk of stomach cancer increases 1.3 times for those who often eat irregular meals and overeat; 1.58 times for those who smoke; the risk of stomach cancer increases 1.58 times for those who like to eat barbecue, fried, fried and smoked foods containing a lot of strong carcinogenic substances – benzo(a)pyrene, and the risk of stomach cancer increases twice for those who often eat such foods; the risk of stomach cancer increases 2 times for those who like to eat hot food. The risk of stomach cancer is 4.22 times higher than that of normal people who like hot food. If the above factors work together, the risk of stomach cancer will be higher. Stomach cancer experts point out that moldy food is often encountered in daily life, and mold is caused by contaminated mold, some of which are toxic fungi and are strong carcinogens, while some foods produce a lot of nitrite and secondary amines under the action of toxic fungi, which can cause cancer by synthesizing nitrosamines in the stomach under certain conditions. According to gastric cancer experts, smoking has a certain relationship with gastric cancer. Smoke contains benzo(a)pyrene, polycyclic aromatic hydrocarbons, dibenzocarbazole and other carcinogenic or pro-carcinogenic substances, which is one of the causes of esophageal cancer and gastric cancer. Although alcohol itself is not a carcinogenic substance, strong alcohol can stimulate the gastric mucosa, damage the mucosal tissue and promote the absorption of carcinogenic substances, and it is more harmful if drinking alcohol and smoking at the same time. Because alcohol can enhance the permeability of cell membranes, thus strengthening the absorption of carcinogenic substances in smoke. Tomatoes contain lycopene and carotene, both of which are antioxidants, especially lycopene, which can neutralize free radicals in the body and is good for anti-stomach and digestive cancers, as well as effective in preventing breast and prostate cancers. Eating onions can reduce the level of nitrite in the stomach, the important onion contains a kind of oak peel substances, for natural anti-cancer substances. Studies show that people who eat onions regularly, the incidence of stomach cancer than people who eat less or do not eat onions to 25% less fatal rate of stomach cancer is also 30% lower. Such foods include mushrooms, shiitake and enoki mushrooms, as well as fungus. Medical experts have found that many mushrooms in food contain anti-cancer substances, which can play a role in cancer prevention. For example, the polysaccharide contained in mushrooms has a very high anti-cancer rate. The polysaccharide contained in black fungus and white fungus is also an effective anti-cancer substance. The crude fiber and calcium contained in mushroom food have anti-cancer effects and can also improve human immunity. People suffering from atrophic gastritis, gastric ulcer, gastric polyadenomatous polyp and pernicious anemia must often go to hospital for examination and treatment to eliminate precancerous lesions and prevent the occurrence of gastric cancer. For malignant tumor like gastric cancer, each of us should actively prevent it, develop good living habits in our daily life, always pay attention to our health condition, and if abnormal symptoms are found, go to hospital for examination and treatment in time, so as not to delay the disease and eventually cause irreparable harm to ourselves.
