[Overview]
Esophagus cancer is the malignant tumor that produces in esophagus epithelial tissue, occupy the 2 ％ of all and malignant tumor. The whole world has 200 thousand person every year to die at esophagus cancer about, at present our country is one of nations with top mortality of cancer of the esophagus on the world, year average mortality is 14.59/10 10 thousand, save lowest with Yunnan among them (1.05/10 10 thousand) , henan province is highest (10 thousand) of 32.22/10. The person that die because of esophagus cancer is next to cancer of the stomach to reside the 2nd, come on the age is in more 40 years old of above, the male over female. Scale of male and female 1.3 ～ 2.7: 1. In recent years 40 years old of person that come on below have growth tendency. The happening of esophagus cancer and inferior saltpetre amine slow sexual excitement, inflammation and traumatic, genetic element and water, the microelement content in commissariat and vegetable is concerned. But exact cause is very not clear, remain to consider to discuss.
[The pathogeny]
Current, the pathogeny of esophagus cancer still does not have complete understanding, the basis already had data analysis, esophagus cancer is not the disease that single factor causes, however the result that collaboration of much element put together uses.
1, inferior saltpetre amine:
Inferior saltpetre amine is by accepted chemical carcinogen, its include: Nitric acid salt, inferior saltpetre salt, 2 class or 3 class ammonium, in tall hair area general consist in waters with food in.
2, mould:
Change with mildew food can cause canceration of the enteron on the animal, mould and inferior saltpetre amine has close to in coordination cancerous action. In esophagus former a hyperplasia other cancer is epithelial inside dissociable the pure individual plant that gives white beads coccus. Disease of reason esophagus fungus may be one of pathological changes of cancerous early days of esophagus cancer.
3, the injury of esophagus wall:
Overheat food, excitant food, coarse food and had taken food to wait for long-term exciting esophagus quickly epithelial and cause chronic inflammation, debaucjed, proliferous, ulcer and cause canceration.
4, hidebound lack with microelement:
No matter domestic and international, esophagus cancer sends an area high to be in natural resources of difference of poor underdeveloped, natural condition, water little, products not the area of abundant. Albumen of animal of the lack in food, adipose, fresh vegetable and fruit fluorine, boracic, magnesian content is low all the happening with esophagus cancer is indirect and relevant.
5, esophagus is chronic inflammation:
Chronic inflammation and canceration have long-term esophagus affinity. Discover esophagus cancer sends an area high in census, esophagus is chronic inflammation incidence of a disease is high also.
6, drink:
Wine itself did not prove to have the sex that cause cancer, but action of cancer having urge, can serve as the dissolvent of carcinogen, high concentration wine can destroy esophagus mucous membrane directly, create a condition for carcinogen. The person that a large number of drinking compares the person that do not drink basically, esophagus cancer incidence of a disease increases 50 times. And smoke of excessive drinking, be addicted to person tower above of the person that drink not to smoke again than both neither 156 times.
