1, change dietary habits: do not eat too hot food, do not eat hot and too rough food. Too hot and rough food in the passage of the esophagus, contact with the mucosal epithelium, will scald the esophageal mucosal epithelium, so that the mucosal epithelium is broken, ulcerated, bleeding and other lesions. Do not eat too fast, do not swallow, do not eat food too fast, avoid accidentally swallowing fish spines, livestock meat bones, etc.. These hard bone spurs will pierce the esophageal wall, the wound is difficult to heal for a while, and it will easily lead to esophageal lesions over time. Do not drink too much strong wine to reduce the stimulation of the esophageal mucosa. Do not smoke and drink less alcohol, because the high alcohol content or other harmful chemicals contained in alcohol may multiply the incidence of cancer in the oral cavity, pharynx, larynx and esophagus caused by smoking; therefore, it is advocated not to smoke and drink less alcohol. Not squatting food, because squatting eating when the pressure in the abdominal cavity increases, food through the cardia into the stomach is bound to be blocked, the esophagus will have to increase peristalsis and pressure to transport food mass. The friction between the food and the esophagus aggravates the damage to the esophageal wall and makes it easy to become cancerous. If the mucosal epithelium is repeatedly subjected to such bad stimulation, the mucosal epithelium will appear some “anomalous” cells with abnormal morphology and function in the process of repeated proliferation and repair, and the accumulation of these abnormal cells will The accumulation of these abnormal cells will gradually develop in a bad direction and lead to malignant changes, and finally form cancer cells that keep expanding. 2.Don’t eat moldy food and less sauerkraut: because moldy food can produce toxins. Sauerkraut contains a large amount of nitrosamines, which have strong carcinogenic effects. Reduce or avoid the intake of nitrosamine chemicals, nitrosamines are a class of chemical carcinogens that are very carcinogenic. Therefore, as far as possible, do not eat long-stored spoiled food, pickled meat food and pickled vegetables, etc. Do not eat moldy food, moldy food is also one of the factors that induce esophageal cancer. Food is easily contaminated by mold when harvesting and storing; cooking oil is easily contaminated by aflatoxin when stored for a long time; vegetables will grow white mold if not kept well. Sufficient intake of riboflavin from food that is vitamin B2, B2 is one of the water-soluble B vitamins, is an important vitamin indispensable to maintain human health. In recent years, some people at home and abroad found that riboflavin deficiency is closely related to the occurrence of esophageal cancer, and riboflavin deficiency is the promotion condition of esophageal cancer. 3, Don’t ignore the early precursors of esophageal cancer: as the saying goes, “three feet of ice is not a day’s cold”, and the development of esophageal cancer is not a matter of night and day; therefore, all middle-aged and elderly people above 40 years old, especially those who come from or live in areas with high incidence of esophageal cancer (more so for men), and those who usually have the habit of eating sauerkraut and drinking alcohol, recently have If you have one or more aura symptoms such as difficulty in swallowing, pain or discomfort behind the sternum, you should not take it lightly and seek medical attention for esophageal exfoliation cytology examination, barium meal X-ray examination, esophagoscopy and biopsy in order to detect the disease at an early stage. As long as the three early, that is, early detection, early diagnosis and early treatment, the survival rate of patients can be greatly improved. Prevention of the disease is far greater than mending the fold.
