Postoperative recurrence of bladder tumors is potentially life-threatening. However, the specifics are related to the tumor characteristics, such as the degree of differentiation, the degree of infiltration, and the presence of metastasis to other parts of the organs. 1. Superficial, highly differentiated tumors without distant metastasis, recurrent bladder tumors are confined within the bladder mucosa, and if they are treated by surgery, then the survival rate is higher and the impact on life is less. 2. tumors invading into the submucosa, beyond the basement membrane, or moderately differentiated tumors without distant metastasis, which have some impact on the survival rate. 3. invasion to the muscular layer or with distant metastasis, or low differentiation, the survival rate is greatly reduced. After the recurrence of bladder cancer, one should consult the doctor for treatment in time, in order to avoid the disease developing to the advanced stage and causing more harm. At present, through drug (mitomycin C, gemcitabine, etc.) treatment and other ways, the growth of tumor cancer cells can be inhibited, which can prolong the survival time of patients to a certain extent. It is suggested that after finding the recurrence of bladder cancer, one should go to the hospital in time for consultation. Cancer stages are different and treatment methods are different, and standardized treatment should be carried out under the guidance of doctors.
