The incidence of esophageal cancer is increasing constantly, more and more patients were esophagus cancer eventually seize the precious life, the esophagus is the food from the mouth to chew stomach channel, it has special function of digestion and absorption. Esophageal tube wall is made from elastic muscle composition, from inside to outside for mucosal epithelium and submucosa, muscular layer, by smooth muscle peristaltic contractions push the food down to the stomach. The esophageal lumen is the innermost layer is mucosal epithelium, thin and soft, direct contact with food, therefore most susceptible to various food stimulation, if too rough, too hot food in esophageal mucosa by contact, will be testing or burn esophageal epithelium, the mucosal epithelial damage, ulceration, bleeding disease. But the epithelial hyperplasia and restoration of function, and soon will be damaged ulceration, bleeding site remediation. If the damage often occurred, continue to stimulate mucosal epithelium, mucosa in repeated hyperplasia, repair, there will be some” variation” of cells, these abnormal cells, is bound to the bad direction, and gradually formed the cancer cells. The proliferation of cancer cells and proliferation, will be in the esophageal mucosa surface appearance hyperplasia, ulceration, bleeding, and gradually protruding into the esophageal lumen or into the esophageal wall intermediate people, resulting in swallowing difficulty and obstruction.
At the beginning, only to swallow, a resistance, the force required to eat liquid food or water down, there is no difficulty, eat the semi-liquid food when there is an obvious difficulty. By the late, cancer tissue plugging the lumen, even pharynx slobber all difficult, also due to malnutrition and wasting, weakness. This is because of bad eating habits formation of esophageal cancer causes.
Thus in the esophagus cancer prevention method, the first step is to correct poor eating habits, do not eat hot and rough food, no good eating habits, as will be sick. At the same time also should eat less excitant strong food, when eating slowly, so as to avoid esophageal mucosa caused by chronic stimulation, but also conducive to food in the stomach digestion.
We can hope for esophageal cancer caused some sufficient awareness, prevention, fundamentally eliminate esophageal cancer invasion.
