Recurrence of rectal cancer is a possibility of recovery. Recurrence of rectal cancer mainly occurs when tumor lesions appear in the operation area after surgical treatment. Tumor lesions are mostly caused by metastasis, such as liver metastasis and lung metastasis, etc., and it will be more difficult to cure. However, patients can still have the possibility of recovery through active and regular treatment in time. If patients are in good physical condition after rectal cancer recurrence and still have surgical indications, they can consider secondary resection surgery for treatment, which can slow down the continuous consumption of tumor lesions on patients’ physical quality and reduce the probability of local infiltration and metastasis as well as distant metastasis of the lesions. After surgery, if the physical condition permits, radiotherapy, chemotherapy and other treatments can also be carried out. If the physical condition of the patient after recurrence is unable to perform surgery, radiotherapy, chemotherapy, immunotherapy and other conservative treatments are needed, which are aimed at controlling and stabilizing the condition and prolonging the survival time of the patient as much as possible. It is recommended that rectal cancer patients should go to the hospital as soon as possible if the disease recurs, and under the guidance of doctors, actively cooperate with doctors and keep optimistic mind.
