Gastrointestinal cancer is a common tumor of the gastrointestinal system, which is divided into early, middle and late stages. The survival time varies from patient to patient due to the development of the disease in different periods and the difference of patients’ own physical quality. If the patient is found in time and undergoes targeted treatment according to the doctor’s diagnosis earlier, the survival time is longer and can even be cured. If the patient actively cooperates with the doctor for rehabilitation after surgery, the survival time may be even longer. If the cancer cells have already spread to other organs and tissues when the patient is diagnosed with bowel cancer, the effect of surgery is not so obvious, and the survival rate of the patient is also lower, probably about 3-5 months, and some patients with better health may survive for about a year.
