's general knowledge of reason that rectal cancer takes place
Not yet till at present ten is clearly demarcated, but the majority thinks that relates to food or heredity. Over the recent more than ten years, the research from every side, prove the absorption of the acid food is the arch-criminal of cancer, cancer is the representatives of the acid physique. In food, the uptake amount of meat, protein, fat improves much, the rectum of large intestine has the tendency to obviously increase, there are quite a few patients who gets intestinal cancer in one's thirties.
1.Chronic inflammation of the rectum: Chronic ulcer colitis, granulation that chronic snail fever form to marry the emergence of rectal cancer, there are direct relations. The longer its course of disease is, the higher the possibility to form rectal cancer happens, the incidence that the ulcer colitis patient of ill more than 20 years forms rectal cancer is about 20- 40%.
2.Adenoma canceration of rectum
3.The diet and carcinogen: Study to reveal the emergence which forms rectal cancer has obvious contacts with economic situation, diet structure in epidemiology. Animal fat and protein are tall in proportion, obviously high in region and colony's morbidity that the cellulose content is low in the developed area, diet. Diet structure and relation that form among rectal cancer take place precise mechanism still totally clear, it is generally acknowledged may catabolite and because of the low cellulose diet state with the intersection of supersession and product, bacterium of animal fat, the intestines wriggle and slow down, the toxin of the intestine absorbs the factor of increasing etc. and has something to do.
4.Inherent cause: Except the family polyp disease or knot rectal cancer patient causing it that ulcer colitis cancerates, among other rectal cancer patients of the knot, nearly 5- 10% of the patients have obvious tumour history of family, it is not the ill rectal cancer of knot (Hereditary Nonpolyposis Colorectal Cancer, HNPCC) of family's polyp to be referred to as heredity ,Also called Lynch syndrome. Embodied in:
( 1) Have three people more than suffer from, form rectal cancer in the kinsfolks, among them two people more than the same generation;
( 2) Two generations of close per persons have illness coming on at least;
( 3) Among them there is a person at least that is to diagnose as that form rectal cancer 50 years old ago.
