Bowel cancer is relatively dangerous. Bowel cancer belongs to one kind of malignant tumor, if it is found in time and regularly reviewed after surgery, the survival rate of patients is still relatively high. If the patient is not found in time or the tumor is late and metastasis occurs, the patient’s life may be in danger. If it is progressive bowel cancer, usually after surgery, chemotherapy or combined with radiotherapy is still needed, the overall survival period of the patient is about 2-3 years, and the 5-year survival rate is 50%-60%. If the patient has advanced bowel cancer, that is, the tumor leads to distant metastasis, such as liver metastasis or lung metastasis, peritoneal metastasis, etc., the overall survival rate is on the low side, usually around 1-2 years.
