How long you can live after colorectal cancer surgery varies from condition to condition and from person to person. Early stage patients may survive for a long time after surgery, and the five-year survival rate of middle and late stage patients may be 20%~60%. The life expectancy after colorectal cancer surgery is related to the surgical method, postoperative clinical staging, and whether there is any follow-up of postoperative treatment. The vast majority of colorectal cancer is already in the middle to late stage when it is found. If there is no distant metastasis and contraindication to surgery in preoperative evaluation, radical surgery can be performed, and if the surgery does not meet the criteria for radical treatment, there is a higher possibility of recurrence in the early postoperative period. If radical surgery is done, a clear pathologic staging can be made using the radical specimen. If it is early stage bowel cancer, further treatment is not necessarily needed after radical surgery, and those with good treatment results can survive for a long time. If it is mid-stage colorectal cancer, corresponding radiotherapy is needed, and the five-year survival rate is about 60%. If it is advanced colorectal cancer, some of them can also undergo radical surgery, and still need further radiotherapy after surgery, while the five-year survival rate is only about 20%. It is recommended to consult the doctor as early as possible and standardize the treatment.
