Rectal cancer recurrence can still be operated again. Rectal cancer is a kind of malignant tumor that occurs in the mucosal epithelium of rectum. It is highly invasive, easy to metastasize and easy to recur. If the patient’s rectal cancer recurs after treatment, he/she can be treated again by surgery to remove a very small part of normal tissues from the lesion. After recurrence of rectal cancer, interventional therapy, targeted therapy, chemotherapy, radiotherapy and other treatments can also be adopted for comprehensive treatment to prolong the survival period of patients. Usually, early rectal cancer can be cured through surgical treatment. In middle and late stage rectal cancer, surgery is the main treatment, supplemented by radiotherapy and chemotherapy. No matter what kind of treatment is chosen, patients should have regular review to prevent recurrence of cancer. If recurrence of rectal cancer is found after treatment, it is recommended that the patient should go to the hospital in time and make diagnosis and treatment plan under the evaluation and guidance of professional doctors.
