High-grade bladder cancer is likely to affect the patient’s life. Bladder cancer is a common malignant tumor of the urinary system, which seriously threatens the health of human beings, especially the elderly. Compared with low-grade cancer, high-grade cancer is characterized by high malignancy, poor differentiation and poor prognosis. Bladder cancer is most common in middle-aged and elderly people, especially men. The most common clinical symptom is painless hematuria throughout the whole process, and the onset of the disease is associated with risk factors such as smoking, long-term exposure to industrial chemicals and chronic irritation of the bladder. If you are diagnosed with bladder cancer, you should actively communicate with your physician and work out an appropriate treatment plan together after a comprehensive and detailed examination. If it is detected at an early stage and treated in an active and standardized manner, the prognosis is usually good.
