Genetic factors are one of the causes of rectal cancer. In the families of rectal cancer patients, about 1/4 of new patients have a family history of rectal cancer. Relatives have had rectal cancer, and their descendants are more likely to suffer from the disease in their lifetime than the general population. The cell genetic genes change, causing malignant cells with the genetic characteristics of the tumor, forming a familial malignant tumor.

· Rectal polyps are the main cause of rectal cancer. Rectal polyps are the main cause of precancerous lesions, especially familial multiple adenomatous polyposis, which has a higher chance of canceration. The canceration rate of papillary adenomatous polyps is about 25%, and the malignant transformation of tubular adenomatous polyps is also relatively common.

Data related to cholecystectomy reported that the incidence of intestinal cancer after cholecystectomy is also on the rise. After a long period of extensive clinical practice, it is believed that this is related to the increase in secondary bile acid entering the intestinal cavity.

Others In addition, the occurrence of tumors is also related to environmental factors (climate, work, etc.), mental factors, age, sexually transmitted diseases, endocrine factors, etc., but rectal cancer can only occur under certain conditions.
