Outbreak rate and death rate of our country are low at the stomach cancer, the familiar malignant tumor of the oesophagus cancer, lung cancer...etc..Food data in recent years everyplace shows to live the exaltation of the level along with the people, structure of change, its outbreak rate present year by year ascend each trend.China and the Japanese's large intestine cancer outbreak rate are obviously low in the United States, but immigrate to the United States generation can immediately see the large intestine cancer outbreak rate ascension, the next generation is basic close the American's outbreak rate.See from the standpoint of Epidemiology, outbreak and environment, life habit of colon cancer, particularly is a food method relevant.
Generally think that high fat recipe and cellulose shortage is main to be taken bad reason.Research shows that the food of saturated fatty acids can increase the density of gall sour and neutral and solid Chun in the colon, and change constitute of coliformses.The gall is sour born through the germ function 3 － A Ji Dan Mao etc. carcinogen, the solid Chun wreath can also be turn by the fragrance but become carcinogen through the germ function.The food fiber includes cellulose, fruit gum, half cellulose, wood quality vegetable...etc., absorption humidity, increment excrement quantity, remain a thing density inside dilution bowel, can shorten time but decrease carcinogen and bowel that the excrement passes large intestine to glue time of film contact, if meal fiber shortage, is already one of the outbreak factors of colon cancer.
Chronic large intestine burning disease, such as ulcer the colon blaze of bowel cancer incidence rate Gao in general crowd, blaze the development process of the increase of disease born nature pathological changes in, often can become polyp, further development is bowel cancer;When the gram Long surname(Crohn) get sick, there is colon, rectum implicating can cause a cancer to change.
Schistosome popular area with don't spread outbreak rate and death rate of colon cancer of area to have obviously distinct, thought chronic schistosome patient's in the past, stimulated because of deposition and toxin of the bowel wall schistosome egg, caused the large intestine glue the film chronic ulcer, blazed sex polyp etc., then caused a cancer to change.This standpoint always in the issue, according to province Jia in Zhejiang kind county schistosome the disease gradually controls, new outbreak example obvious decrease, the later period patient tends at the disappearance, but the outbreak rate of colon cancer be still very high.
Statistics according to the general data, there is the sufferer of colon polyp, the outbreak rate of colon cancer is have no colon polyp sufferer of 500%.The household delivers sex bowel polyp lump more, the cancer change of the incidence rate be higher.
