Gastric carcinoma is a malignant tumor originating from the epithelium of the gastric mucosa, which is the most prevalent among all kinds of malignant tumors in China, and there are obvious geographical differences in the incidence of gastric cancer. Due to the change of diet structure, increasing work pressure and infection of Helicobacter pylori, the incidence of stomach cancer is becoming younger. What kind of lifestyle can prevent the occurrence of gastric cancer? 1.Healthy diet No or less smoked, pickled and barbecued food, more fresh vegetables and fruits. 2.Quit smoking Quit smoking can reduce the occurrence of many diseases, which is also good for people around you and reduce the harm of second-hand smoke. 3.Low salt diet Low salt can not only prevent the occurrence of stomach cancer, but also reduce the occurrence of lung cancer and oral cancer, and reduce the occurrence of cardiovascular disease. 4.Keep enough sleep Cancer cells are formed by mutation during normal cell division, and night is the most vigorous period of cell proliferation. If you do not sleep well, your immune system and anti-disease ability will be significantly reduced, so it will be more difficult to control the mutation of cells and form cancer. Especially for those who stay up late, they often smoke a lot to refresh themselves, which makes it easy for more carcinogens to invade the organism. 5.Treat precancerous lesions in time Chronic atrophic gastritis, chronic ulcers, adenomas and polyps are precancerous lesions of gastric cancer, if these diseases are found, treat them in time. The risk of cancer is more than three times higher than that of ordinary people. People with this kind of personality are introverted and often over-restrain and suppress their bad emotions such as sadness, anger and bitterness, and do not let them out in time. The long-term effect of bad emotion on human body will lead to endocrine disorder and lower immune function, which will give cancer a chance to take advantage of. Therefore, it is important to keep your mood relaxed and vent your bad emotions in time for cancer prevention.
