Cancer of the stomach is one of malignant tumor with the commonnest whole world, it is the 4th big malignant tumor, die in one's bed leads the 2nd when rank malignant tumor. Pylorus screw bacterium already was labelled by the international cancer research organization of subordinate of World Health Organization 1994 human cancer of the stomach I kind (affirmative) cause cancer former, but pylorus screw bacterium cuts the forehead to send cancerous mechanism truly still very not clear, can infection of pylorus screw bacterium bring about happening of cancer of the stomach? Does pylorus screw bacterium catch the prime criminal that is cancer of the stomach? We can answer this question from epidemiology respect.
Pylorus screw bacterium affects the epidemiology with cancer of the stomach
Epidemiology considers to make clear, the whole world has the crowd of more than 50% to affect pylorus screw bacterium, concentrated degree, public wholesome requirement and fountainhead supply infection of pylorus screw bacterium and socioeconomy level, population have closer relationship. And in the developing country with low socioeconomy, age of infection of pylorus screw bacterium is early and the area with infection high rate, the occurence rate of cancer of the stomach is high also. But although the crowd that exceeds an in part affects pylorus screw bacterium, but the whole world has inadequacy the person of 2% develops finally for cancer of the stomach. At present medical bound thinks:
Infection of bacterium of 1. pylorus screw is the requirement that bowel cancer of the stomach produces, but not be sufficient condition, affected pylorus screw bacterium that is to say, do not mean regular meeting to have cancer of the stomach certainly.
The happening of 2. cancer of the stomach is infection of pylorus screw bacterium, genetic element and environmental element the result of joint action.
3. environment element is next to pylorus screw bacterium to affect in the action in happening of cancer of the stomach.
Bacterium of screw of 4. eradicative pylorus can make risk of happening of cancer of the stomach drops 34%-50% .
What crowd recommends bacterium of eradicative pylorus screw?
Major person affected pylorus screw bacterium, can do not have a symptom, only little part person can appear bellyacke, abdominal distension, appetite drops, return sick at heart, belch, angular, the symptom of gastric bowel path such as heartburn, it is OK to still have one part patient occurrence halitosis, hidebound wait for the symptom beyond enteron. Can diagnose through exsanguinate or expiratory experiment whether pylorus screw bacterium is affected.
Suffer from digestibility ulcer (no matter whether activity and have do not have complication) , chronic gastritis companion has dyspeptic symptom, chronic gastritis to accompany atrophy of gastric mucous membrane to take proton pump depressor erosion, for a long time, have cancer of the stomach familial history, the plan takes the body that be not steriod for a long time to fight phlogistic medicine, unidentified cause. These crowds should detect to the hospital regularly pylorus screw bacterium, if masculine gender is recommended,undertake eradicating remedial, prevent development to be cancer of the stomach.
