Definition

Colorectal carcinoma is a malignant tumor arising from colonic epithelium. More than 90% of colorectal carcinomas (CRC) are adenocarcinomas.

The cause and pathogenesis of CRC are related to both environmental and genetic factors. Environmental factors contain diet rich in meat, high fat, carbohydrate, low fiber; lifestyle risk factors like cigarette smoking and alcohol consumption; and those which have effect on the intestinal microflora and chemical composition of the intraluminal content. Bile acids and their metabolites derived from bacterial action could also be potential carcinogen. Some vitamin deficiencies (vitamins B2, B6, B12, C, D, folate, etc.) have risk for CRC. The repeated colonic mucosal injury and repair as occurs in chronic idiopathic inflammatory bowel disease are important in the development of CRC. Various genetic factors are as follows: there is high predisposition for CRC...
