's prevention and health care of common cause of disease of cancer of colon
Cancer of colon is one of the common malignant tumour, have the highest morbidity with 40 years old - 50 years old age groups. According to epidemiology of the world's investigation, find the morbidity in North America, western Europe, Australia, New Zealand and other places of cancer of colon is the highest, occupy by kinds of tumour the top two on viscera,but in inferior, Latin America and other places morbidity getting getting lower more very. The incidence and mortality of our country is lower than gastric carcinoma, common malignant tumour such as cancer of the esophagus, lung cancer. The regional materials reveal with the improvement of the living standards of the people, change of the diet structure in recent years, its morbidity presents every last trend year by year. The cancer morbidity of large intestine of China and Japanese is obviously less than U.S.A., the first generation reaching U.S.A. of immigrant can see the cancer morbidity of large intestine rising, the second generation of morbidity basically close to Americans. From the viewpoint of epidemiology, the morbidity of cancer of colon is involved in environment, habits and customs, especially diet way.
It is generally acknowledged it is the main pathogenic factor that fatty recipe and cellulose are insufficient. Research reveals, the diet of the saturated fatty acid can increase the density of bile acid and neutral firm alcohol in colon, and change the composition of fungus group of large intestine. Bile acid apply, can turn into 3 - the intersection of methyl and the intersection of gallbladder and the intersection of anthracene,etc. and carcinogen by bacterium, firm the intersection of alcohol and ring can also apply by bacterium fragrant to take and form carcinogen. Food fiber include cellulose, pectin, half cellulose, lignin,etc., absorb the moisture, increase excrement and urine quantity, dilute the residue density in the intestines, can shorten the excrement and urine and reduce the time that the carcinogen contacts with the enteric mucous membrane through time of the large intestine, when the meal fiber is insufficient, it has already been one of the morbidity factors of cancer of colon.
