The occurrence of esophageal cancer has nothing to do with eating habits, and bad eating habits can induce esophageal cancer, so if you want to prevent esophageal cancer, you should change bad eating habits from now on. The innermost layer of esophageal cavity is mucosal epithelium, which is thin and soft and in direct contact with food, so it is most vulnerable to stimulation by various foods. However, the mucosal epithelium has the function of proliferation and repair, and will soon repair the broken ulcerated and bleeding parts as before. If this kind of damage occurs frequently and constantly stimulates the mucosal epithelium, some “mutated” cells will appear in the repeated proliferation and repair of the mucosa, and more of these abnormal cells will inevitably develop in a bad direction and gradually form cancer cells. The spread and proliferation of cancer cells will lead to hyperplasia, rupture and bleeding on the surface of esophageal mucosa, and gradually protrude into the lumen of esophagus or deep into the middle of esophageal wall, causing difficulty and obstruction when swallowing food.
