The recurrence time after bladder cancer elective surgery may be around three months to six months after surgery or two years after surgery, but the exact recurrence time is different from person to person. There are two peaks of recurrence after bladder tumor electrodessication, one is three to six months after surgery, often due to very small lesions that are undetectable at that time. The other is about two years, determined by the biological behavior of bladder cancer. However, the specific time of recurrence is related to the malignant degree of tumor treatment mode and the patient’s own state and other factors. Bladder cancer may recur for life after cystectomy, so the review after cystectomy is very important and long-term follow-up is needed. Early detection and early treatment can maximize the life of patients.
