The cause of disease of oesophagus cancer learns with factor

The oesophagus cancer really slices a cause of disease not clear.Obviously, environment and some carcinogens are important with the result that the cause of disease is plain.
(A)second nitric An compound and fungi toxin have already known that about 30 kinds of second nitric Ans can induct animal tumor now.Domestic also already the successfully applied A Xia second nitric An, the muscle An sour B ester second nitric An, AN E and second nitric An induct the oesophagus cancer of big rat with two ethyls second beard An etc.s.The our country survey discovers that in Gao Fa Qu's food and drinking, the nitrate, second nitrate and second class An content show Zhao to increase Gao, and and ground oesophagus cancer and increase on tare degree of oesophagus rare of fall ill the rate present just related these materialses to easily synthesize second carcinogen nitric An in the stomach.
(Two)the oesophagus hurt, oesophagus disease and the incitement function oesophagus harm and some oesophagus diseases of food can urge hair oesophagus cancer.At causticity oesophagus burn and narrow, oesophagus Ben door lose idle disease and oesophagus Qi room or anti- flow sex of in the oesophagus burning sufferer, the outbreak of oesophagus cancer leads more general crowd is Gao.According to calculate is because be detained inside the oesophagus but to long term of chronic burning disease, ulcer, or chronic stimulate, then increase to living on skin of oesophagus, finally cause cancer's changing.The Epidemiology survey discovers that oesophagus cancer Gao Fa region's residents have the habit to take a meal very hot food, drink strong drink, eat a great deal of pepper and chew betel nut or cut tobacco, these oesophaguses glue the chronic physics and chemistry incitement of film, all can cause partial last skin cell to increase to living.The animal experiment proves that fill the air skin of sex or cooking stove in the bureau increase to living may be a before the cancer expecting of the oesophagus cancer pathological changes.
(Three)malnutrition and trace element lack to absorb the animal egg white shortage and vitamin A, B2 and C to lack, is oesophagus cancer high area residents the common characteristics of the food.But mostly the high hair region of malnutrition, oesophagus cancer not Gao Fa, past this isn't likely to be a predominant factor.
(Four)the outbreak of heredity factor oesophagus cancer often express the family gathering phenomenon.The survey in the our country provinces, such as mountain west, Shandong and river south...etc. discovers that have a male household history have 1 around 4~12.There is comparison Gao of male household history in Gao Fa Qu, among them, the paternity is the tallest, matriarchal society time it.
