There are gastric carcinomas too " Racial discrimination " ? 's general knowledge
The morbidity situation of gastric carcinoma, all have obvious differences in different areas, different ethnic groups. The coloured race is apter to suffer from a disease than the white race.
Japan, Chile, Russia, Iceland, for being high to send country, U.S.A., Australia, western Europe country morbidity lower, our country is between the two. But in near these decades, the morbidity of gastric carcinoma of the western countries has had obvious downward trends, take U.S.A. as examples, the mortality of gastric carcinoma has already dropped to 5/10 of the the Wan 's from 22/10 of the original the Wan 's. Japan has a downward trend too in recent years, there is not obvious rise or fall in our country. Among patient, mostly man, than about 2- 3:1 men and women. Over 40 is the main morbidity. At present, the precise reason of gastric carcinoma has not been expounded yet. Epidemiology investigate gastric carcinoma to be easy to take place on lower social economic stratum, relate to environmental factor. The relation between diet and gastric carcinoma is extensive research. Eat the food with rich nitrate of density for a long time, for instance smoke and pickle fish, salted vegetables, can all increase the danger that gastric carcinoma take place. Nitrate is absorbed, is secreted by the saliva, and then get back to the stomach quickly after taking in, change into inferior nitrate after the bacterium is applied, and then bind with amine in the stomach and form carcinogenic inferior nitre amine. Gastritis hour, carcinogen - -Inferior nitre amine, act on the mucous membrane of stomach and can cause the canceration for a long time, generally takes 20- 30 years.
Discover gastric carcinoma high person who take place the intersection of pylorus and the intersection of spiral shell and the intersection of bacillus and the intersection of antibody and level higher than low person who take place obviously in the crowd in recent years, its fungus type infected has certain gathering nature. Someone makes antigen with the gastric carcinoma patient's spiral shell's bacillus of pylorus, the interval cluster relation takes place to reflect gastric carcinoma high. At present, spiral shell's bacillus of pylorus has already been determined as first class carcinogen that human gastric carcinoma takes place by the international cancer research center, it is the new theory of leading to the fact gastric carcinoma takes place.
The inherent cause, to the morbidity of gastric carcinoma, it is also very important. The intersection of family and phenomenon of gastric carcinoma take place more in the same as the intersection of ovum and compatriot, in the only family of twins. Long-term clinical observation, five kinds of diseases are apt to develop into gastric carcinoma, the situation before called cancer, if chronic person who wither gastritis accompany the intersection of intestines and catch, the intersection of stomach and polyp, incomplete gastritis, make stomach excise postoperative mostly, usually more than did not happen in 15 years after the operation in the canceration. Pernicious anemia and a few gastric ulcer patients.
It is successively the intersection of stomach and sinus department, cardia, body of stomach, the whole stomach or most stomaches that gastric carcinoma is kind to take place the position.
