How does rectum cancer come into being

Reason 1: Rectal chronic inflammation: chronic ulcerative colitis, granuloma caused by chronic schistosomiasis are directly related to the occurrence of colorectal cancer. The longer the course of disease, the higher the possibility of colorectal cancer. The incidence of colorectal cancer in patients with ulcerative colitis more than 20 years is about 20% to 40%.

Reason 2: diet and carcinogens: the occurrence of colorectal cancer is obviously related to economic status and diet structure. The incidence rate of fat and protein in the economically developed areas and the low proportion of animal cellulose and protein in the developed areas is obviously higher. The exact mechanism of the relationship between dietary structure and colorectal cancer is not fully clear. It is generally believed that it may be related to the metabolites of animal fat, bacterial decomposition products, intestinal peristalsis slowing down and intestinal toxin absorption increasing due to low cellulose diet.

Reason 3: genetic factors: in addition to colorectal cancer patients caused by familial polyposis or ulcerative colitis malignant transformation, about 5-10% of other colorectal cancer patients have obvious family tumor history, which is collectively referred to as hereditary non familial polyposis colorectal cancer.
