Multiple bladder cancer is a kind of bladder cancer, if there is no invasion to the muscle layer usually can be transurethral bladder tumor electrolysis, but if the infiltration to the muscle layer, radical cystectomy or partial cystectomy is recommended. If the malignant bladder tumor does not invade the muscle layer, transurethral cystectomy is generally preferred. This procedure is less invasive, has less bleeding, and results in faster postoperative recovery. Patients need to receive bladder perfusion therapy, etc. as appropriate after surgery to improve prognosis and reduce recurrence, etc. If the tumor infiltrates the muscle layer, or the invasion is diffuse, or local infiltration or regional lymph node metastasis occurs, radical cystectomy or partial cystectomy is feasible. Which treatment option to use needs to be decided according to the specific conditions of the tumor, the patient’s physical condition, and the relevant laboratory test data. If a bladder tumor is suspected or diagnosed, it is recommended to go to a regular hospital for a comprehensive assessment of the condition, follow the doctor’s instructions to cooperate with the treatment, and choose the appropriate treatment plan to avoid delaying the condition.
