summary

The incidence of colon cancer is mainly related to high-fat and low cellulose diet. Familial multiple enterosarcoma has a higher incidence of canceration. Genetic factors may also be involved in the pathogenesis of colon cancer. In the early stage, there can be no symptoms. In the middle and late stage, abdominal distension and dyspepsia can be manifested, and then there will be changes in defecation habits, abdominal pain, mucus or bloody stools. After tumor ulceration, blood loss and toxin absorption, anemia, low fever, fatigue, emaciation, lower extremity edema and other symptoms often appear.
