There is actually no exact answer to how many years a patient can live after bowel cancer surgery, because the patient’s survival after surgery is affected by many factors, such as individual’s physical condition, pathological type, clinical stage of cancer, surgical removal of cancer cells and postoperative care. However, usually, a simple prediction of patient survival can be made based on the clinical stage of cancer. The survival rate of stage I bowel cancer patients can usually reach more than 90% at 5 years after surgery. For stage II to III patients, standardized chemotherapy or combined radiotherapy after surgery can usually extend life expectancy with 5-year survival rate of 60%-80%. In contrast, if stage IV bowel cancer patients do not actively cooperate with treatment, their survival time is only a few months or so. If they can be actively treated, their life expectancy can generally be extended by 1-3 years. Of course, further judgment should be made according to the patient’s tolerance level of radiotherapy and the nutritional status of the whole body. Thus, if bowel cancer patients can be detected and treated early, it can help prolong the survival period. Moreover, early stage bowel cancer patients can be cured by surgery as the cancer cells have not spread and metastasized yet. Therefore, bowel cancer patients must actively cooperate with the treatment, and at the same time, maintain a balanced nutritional intake and have an optimistic attitude during the treatment to prolong the survival period as much as possible.
