What _'s general knowledge of cause of disease does gastric carcinoma have
Studies have suggested, the emergence of gastric carcinoma relates to the following factors, namely diet structure and diet behavior, environmental factor, inherent cause, the other diseases of the stomach. The very single function of these factor or cooperative effect, the emergence which cause gastric carcinoma.
1 bad diet structure and diet behavior
(1)Salt the smoked food down
The residents of the high taking place area of gastric carcinoma like to eat smoke cured jerky, salted fish or crab paste,etc. more. The pickling the food of high salt has facilitation on emergence development of gastric carcinoma. Smoke and contain more multiloop aromatic hydrocarbon of carcinogen in the food, a representative one of multiloop aromatic hydrocarbon is 3, 4 benzene combines Zhyuan, 3, 4 benzene and Zhyuan can cause stomach tumour.
(2)Lack the fresh vegetables, fruit and milk in the diet
A lot of research verifies, lack the fresh vegetables, fruit and milk in the food, it is a gastric carcinoma patient or prominent characteristic of high crowd of taking place area of gastric carcinoma. Fresh vegetables and fruit are rich in vitamin, vitamin C and Vitamin E can inhibit the formation of carcinogen inferior nitre amine in the stomach, vitamin A can prevent the canceration of epithelial tissue. Rich in vitamin A and protein colloid in the fresh milk, can protect the mucous membrane of stomach and avoid being effected by carcinogen. So, lack the fresh vegetables, fruit and milk, it is the dangerous factor that gastric carcinoma takes place.
(3)Mix the talc powder in the diet
Japanese like mixing a small amount of talc powder in the porridge, make it have a slippery comfortable sense while eating. According to studying, per gram of talc powder contains 3,700,000 pieces of asbestos fiber, and the asbestos fiber has function of bringing out gastric carcinoma. So someone think Japanese might relate to this eating habit while being high to take place gastric carcinoma.
(4)Eat the food stored and gone mouldy for a long time
It is of our country for gastric carcinoma high taking place area's eat to store the residents by food that be gone mouldy for a long time often,and can last song fungus, song moulds yellows variegated, last nest song fungus,etc. mould on gastric juice of it, variegated song fungus toxin that the mould produces, yellow aspergillus toxin,etc. can bring out gastric carcinoma.
(5)Like to eat and scald the food, take food fast, when the breakfast,lunch and dinner is indefinite
It if you can't discover it like, take iron by food, eat fast with when breakfast,lunch and dinner is indefinite,getting more apt to cause stomach mucous membrane not to be damaged, and become the morbidity inducement of gastric carcinoma.
2 environmental factor
Find, often gather in the volcanic rock area in the high taking place area of gastric carcinoma according to the national gastric carcinoma integrated survey result, the content of nickel and cobalt is high in the drinking water, and the content of selenium is low; Often gather in the limestone area in the low taking place area of gastric carcinoma, the content of microelement is opposite to the former in the drinking water. Studies have suggested, elements such as nickel and cobalt,etc. are carcinogenic or urges cancer function, but selenium restrains cancer function.
3 inherent cause
There is family's assembling nature in gastric carcinoma. Though same living condition and eating habit can make the family living together produce to the easy suffering from of a certain disease, but this kind of easy suffering from usually shows among children of parents with direct blood relationship, seldom see between the couple living together. This shows except the function in external carcinogenic factors such as the eating habit, living condition,etc., certainly also have function of the inherent cause.
Other diseases of 4 stomach
The benign diseases of some stomaches have offered very direct precondition for emergence of gastric carcinoma. The chronic withering gastritis patient's gastric acid is low or scarce, make the content of positive bacterium of reductase nitric acid in the stomach rise. It was synthetic that this kind of bacterium participated in the endogenous inferior nitre amine compound, and such inferior nitre amine compound has obvious carcinogenic function. Can be thought, chronic shrinking gastritis are the important inducement that gastric carcinoma takes place.
