Causes of esophageal cancer

summary

Esophageal cancer is a malignant lesion formed by the abnormal hyperplasia of esophageal squamous epithelium or glandular epithelium. Some esophageal cancers can be detected early and cured completely. Understanding the etiology of esophageal cancer is of great help to the treatment and prevention of esophageal cancer. Let me talk about the cause of esophageal cancer

Causes of esophageal cancer

First, chemical reasons. Some nitrosamines can cause esophageal cancer. People in high incidence areas like to eat sauerkraut. The determination and analysis show that the sauerkraut contains nitrite, nitrate, secondary amine, etc. these chemicals are precursors of nitrosamine. The consumption of sour vegetables is directly proportional to the incidence rate of esophageal cancer. 　

Second: mold pollution. In some areas with high incidence of esophageal cancer, it is common for people to eat moldy food, and the situation of grain mold pollution is more serious. Eating moldy food is also related to the occurrence of esophageal cancer.

Third: local injury of esophagus. Long term like into hot diet may also be one of the factors of cancer. Prolonged esophagitis caused by various reasons may be the pre lesion of esophageal cancer, especially those with mesothelial cell formation. It has been reported that esophagitis is closely related to esophageal cancer. Esophagitis often occurs about 10 years earlier than esophageal cancer.

matters needing attention

Long term smoking and drinking are related to the incidence of esophageal cancer. It has been studied that the incidence rate of heavy drinkers is 50 times higher than that of non drinkers. The number of smokers is 7 times higher than that of non smokers. The incidence rate of alcoholics and smokers is 156 times that of non-smokers and non-smokers. In particular, the risk of esophageal cancer is higher in those who drink alcohol.
