The survival time of bowel cancer patients is related to the stage and differentiation degree of the tumor. Clinically, the five-year survival rate is mostly used to judge the survival time of bowel cancer patients. Bowel cancer is the most common gastrointestinal tumor in clinical practice and requires active treatment, which can prevent the proliferation and metastasis of cancer tissues while helping to reduce pain. In terms of survival, the five-year survival rate of stage I bowel cancer patients can reach about 90%. The five-year survival rate of stage II bowel cancer patients is about 60%-70%. The five-year survival rate of patients with stage III bowel cancer is about 40% after surgical treatment and chemotherapy, and the five-year survival rate of patients with stage IV bowel cancer is about 10%, which is relatively low and the risk of recurrence and metastasis will increase. Patients with bowel cancer, no matter what stage they are in, need to seek timely medical attention for colonoscopy to clarify the patient’s condition and then give the next step of treatment. Patients with bowel cancer are related to irregular daily diet and preference for stimulating food, so they should be given a light diet during treatment.
