(1) smoking some high incidence area residents esophageal cancer, smoking rate is very high, and some of the residents do not smoke, very rare esophageal cancer. This is because cigarettes contain several nitrosamines, a carcinogenic nitrosamines have a strong role.
(2) drinking Western Europe and North America the survey found that many patients with a large number of drinking wine or most of the workers and staff. Patients with esophageal cancer in the United States drink whisky higher than the general population 25 times, 10 times higher beer. Alcohol itself has no carcinogenic effects, it may be carcinogenic solvents, carcinogens easy access to esophageal mucosa, but also enable the esophageal mucosa alcohol dehydration caused esophageal mucosa injury and create conditions for the occurrence of esophageal cancer.
(3) bad eating habits and long-term malnutrition eating overheating, tough, rough food and spicy food irritation, may cause esophageal mucosal injury, repeated damage can cause mucosal hyperplasia of change, which leads to carcinogenesis. Tumor Institute of the Chinese Academy of Sciences in the human body, the environment, the role of carcinogenic nitrosamines found in a study of esophageal cancer Linxian high incidence area residents eat sauerkraut contains a variety of nitrosamines, and to prove that the consumption of the sauerkraut with esophageal cancer incidence rate is proportional. In addition, Shantou University Medical College, the high incidence area of Guangdong Province esophageal cancer Nan'ao county water, fish sauce, gravy, vegetables, dried turnip containing a variety of nitrosamines in both, and these foods preserved in the course of fungal contamination often , mold can promote food nitrosamine content increased significantly. Mold and animal model of esophageal cancer has been confirmed in the mold role in the pathogenesis of esophageal cancer.
Generally high incidence area of esophageal cancer in infertile soil, poor nutrition in poor areas, lack of dietary vitamin, and particularly vitamin C and vitamin B2, the lack of protein and essential amino acids. The esophageal mucosa can be hyperplasia change as further cause cancer. Trace elements iron, molybdenum, zinc, and also the lack of related to the occurrence of esophageal cancer.
(4) the esophageal mucosa chronic inflammation of the esophagus stimulated some state and abnormal esophageal diseases such as diverticulitis, narrow scar clip, esophageal inflammation, Achalasia, Meku can happen and malignant form of esophageal cancer.
(5) genetic susceptibility scientists after extensive investigation and found that esophageal cancer has been significantly family aggregation.
