Esophageal cancer is the world some countries and regions common malignancy. The World Health Organization released statistics show that the mortality rates of esophageal cancer in China as the highest male death of esophageal cancer for the second place, after gastric cancer. Esophageal cancer is the third woman, after gastric cancer and cervical cancer.
China's great differences in the incidence, Henan, Hebei, Shanxi provinces at the junction of the Taihang Mountains area, Henan Province Linxian, and Cixian County in Hebei Province in Yangcheng County, as the representative of the highest incidence rates. Jiangsu areas such as the northern part of the higher incidence of Henan Linxian 35 ~ 64-year-old males the incidence of esophageal cancer is one of the world's high incidence area.
Distribution of 15,000 foreign esophageal cancer in the vicinity of Central Asia, Africa, Latin America and northern France. Esophageal high incidence area of drinking water, grain and vegetables in manganese, molybdenum, iron, chlorine, zinc, sodium, selenium, phosphorus, low iodine content of food in the higher levels of nitrosamines, fungal contamination more, a some fungi can promote the formation of nitrosamines. Inhalation potent tobacco, chronic stimulation, inflammation and trauma, such as the perfect food, the Food and overheating, excessive eating, long-term alcohol drinking, oral or unclean dental caries, the lack of food in vitamin A, B, C, or the lack of protein in the food, fresh vegetables and fruit, etc., as well as genetic factors may be related to the occurrence of esophageal cancer. In short many of the causes of esophageal cancer, to be continued in-depth study.
