How far bladder cancer develops in a month is mainly judged according to the pathological typing of the tumor and the growth of the tumor. 1. Pathological typing of the tumor: bladder cancer grows slowly, and in clinical pathological typing, it manifests as non-muscle invasive bladder cancer, which has a 5-year survival rate of more than 90%, but is prone to recurrence. Muscle invasive bladder cancer progresses faster and usually requires radical cystectomy or other comprehensive treatments (chemotherapy, etc.). 2. Tumor growth: The tumor grows superficially and is located in the mucous membrane layer, which is non-muscle layer invasive bladder cancer. This kind of pathological staging grows slowly and may have no change within one month. The progression of bladder cancer is related to the pathologic type and so on, and varies from person to person and from disease to disease. Clinically, for patients with bladder cancer, it is recommended to consult the urology department of regular hospitals.
