There is still a possibility of recurrence after chemotherapy after colon cancer surgery, so it is important to have regular review.
Postoperative chemotherapy for colon cancer can help eliminate local residual lesions and significantly slow down the progress of the disease. However, colon cancer is prone to recurrence and distant metastasis, especially in middle and late stage. Therefore, timely postoperative adjuvant chemotherapy can reduce the recurrence rate of colon cancer, but it cannot guarantee that colon cancer will not recur.
Three years after surgery is the peak period of recurrence of colon cancer, during this period, CEA test and colonoscopy should be carried out regularly, and should be accompanied by imaging examination, once recurrence is detected, it should be treated in time, so as to improve the quality of life of colon cancer.
