High incidence of esophageal cancer a major factor!

The exact etiology of esophageal cancer unknown. According to the experts found, Environment and certain carcinogenic substances is an important pathogenic factor. 1. Role of alcohol and tobacco Alcohol is the number of esophageal cancer is very important pathogenic factor in one of the factors, the risk of esophageal cancer and daily alcohol, tobacco consumption was directly proportional to the quantity, and alcohol, tobacco and the incidence of dangerous than tobacco or alcohol alone higher than the risk of several tens of times. 2. Nitrosamine compounds and mycotoxins Now known that nearly 30 kinds of nitrosamines can be induced animal tumor. Marinated and moldy food contain nitrosamines compounds and fungal toxins. In the high incidence area of food and drinking water, nitrate, nitrite and secondary amine content was significantly higher, and local and esophageal cancer and esophageal epithelium proliferation of severe illness rate was positively related to these substances in the stomach easy synthesis of tumor material nitrosamines. 3. Malnutrition and the lack of trace elements Inadequate intake of animal protein and vitamin A, B2, E, C lack of trace elements molybdenum, zinc, magnesium, manganese, cobalt, iron, such as the lack, as well as the lack of fresh fruit and vegetables are susceptible to esophageal cancer. 4. Esophageal injury, esophageal diseases, as well as food stimulation High incidence of esophageal cancer in the residents eat very hot diet, drinking spirits, eating large pepper, tobacco or betel nut chewing habit, esophageal mucosa chronic physical and chemical stimulation could induce local epithelial cell proliferation. 5. Genetic factors The incidence of esophageal regular performance family of aggregation. In China, Shanxi, Shandong, Henan Province survey found that from about 1/4-1/2 positive family history. Which patrilineal highest maternal times. Research found that certain diseases are the esophageal tumors state: 1) esophageal mucosa too short; 2) chronic esophagitis; 3) the corrosive esophageal lesions; 4) Giant esophageal disease; 5) throat cancer history; 6) cancerous tumor esophageal diverticulum; 7) Plummer Vision Syndrome, caused by iron deficiency anemia.
