What are the main causes of rectal cancer ? The specific causes of rectal cancer are as follows:

1. Diet and carcinogens: The exact mechanism of the relationship between dietary structure and the cause of rectal cancer is not yet fully understood.

2. Chronic rectal inflammation: Chronic ulcerative colitis and granulomas caused by chronic schistosomiasis are directly related to the occurrence of colorectal cancer. The longer the course of the disease, the higher the possibility of rectal cancer.

3. Genetic factors: In addition to the causes of rectal cancer caused by familial polyposis or malignant transformation of ulcerative colitis, in other colorectal cancer patients, they are collectively referred to as the causes of hereditary non-familial polyposis rectal cancer.
