Esophageal cancer is a prevalent malignant tumor in China, which greatly affects the normal diet of patients. Improper diet especially often eating too hot food is more likely to lead to its occurrence, why? People who often eat hot food do not feel hot even at very high temperature, but when they are exposed to hot food and hot drinks at about 75℃, the delicate oral and esophageal mucosa will be lightly burned, and the burned mucosal surface will be shed and renewed in time, and the cells at the base will be rapidly proliferated, renewed and replenished, and over time, if the speed of proliferated cells is abnormally accelerated or mutated under bad stimulation, bad tendency will occur, what’s more Physical stimulation and high temperature are also items that have received much attention in the world to explore the causes of cancer. In addition, the thickened mucosa will be thickened due to the heat stimulation of the mucosa, and the thickened mucosa will become more and more insensitive to heat stimulation, plus the nerve reflex of the esophageal mucosa is already very slow, so it will become more and more not afraid of heat, and the more not afraid of heat, the more dare to eat hot things, and the hotter you eat, the thicker the oral mucosa will be. In this vicious circle, people will involuntarily accept more and more serious burn stimulation. The damage caused by this irritation may also lead to untreated esophagitis, which is sometimes accompanied by interstitial cells, and some suggest that this may be one of the precancerous lesions. At autopsy, esophageal cancer is often present along with esophagitis, and esophagitis often precedes esophageal cancer by 10 years. In addition to consuming overheated food, such as eating hard and rough food, or swallowing too fast and preferring spicy and stimulating food, can easily lead to damage to the esophagus, thus triggering the disease. To prevent the occurrence of esophageal cancer, eat more fresh vegetables, do not eat too much, control meat and do not gain too much weight, which can reduce the incidence of cancer. Keep a happy mood and don’t be depressed by sulking. According to Chinese medicine, liver qi stasis, liver depression and qi stagnation will directly affect the transportation and gasification function of the spleen and stomach, and prolonged depression and stagnation will result in blockage of qi and blood, and blockage or stagnation of meridians, resulting in changes such as qi stagnation, depression, aggregation, knots, obstruction, choking and hiccups. Therefore, a happy mood and relaxed liver energy play a vital role in the prevention of esophageal cancer.
