Untreated bladder cancer will seriously jeopardize the patient’s life, reduce the quality of life, and eventually lead to death, so it is necessary to cooperate with doctors for treatment after diagnosis. Bladder cancer is a malignant tumor of the urinary tract, which can be caused by many factors, such as smoking, exposure to harmful chemicals at work or in life, and low daily water intake. Generally, after diagnosis, it needs to be treated by a combination of various therapies such as surgical resection, chemotherapy, bladder perfusion therapy and radiotherapy. After active treatment, early stage bladder cancer patients can get about 80% five-year survival rate. However, if they do not cooperate with doctors in time, the prognosis will be seriously reduced when the disease develops to advanced stage or even terminal stage, which may even lead to death of the patients, so they should actively cooperate with doctors in treatment.
