High-grade bladder cancer cannot be completely cured, but after effective treatment, patients can return to normal life, but they need to follow up and review in hospital for life. The reason why cancer cannot be completely cured is that it may have distant metastasis and recurrence, and after the distant metastasis and recurrence, the tumor may progress, leading to organ dysfunction and further life threatening. Therefore, when suffering from tumor, early evaluation is needed, and if it meets the indication of surgery, surgical treatment can be performed first, such as tumor removal or partial cystectomy, or total cystectomy to remove the tumor visible to the naked eye in the body. Tumor-free survival in vivo can basically maintain a normal life with only lifelong follow-up, and the probability of metastatic recurrence still exists in the distant future.
