It is wrong to say that bladder cancer is not a fatal cancer. Some patients may have a better prognosis, but some of them have a worse prognosis with fatal risk. Bladder cancer is a malignant tumor that occurs on the bladder mucosa. Survival and quality of life of such patients are relatively good, and generally do not affect their life expectancy after active treatment. In addition, there are also muscle invasive uroepithelial carcinoma of bladder cancer, which is highly malignant and can threaten patients’ life. Patients with bladder cancer may have painless, intermittent, naked-eye hematuria throughout the whole process. When the tumor volume increases, symptoms such as difficulty in urination, frequent urination, urgency and pain in urination may appear, and when metastasis occurs in the advanced stage of bladder cancer, it is usually accompanied by multi-organ failure. Patients with non-muscle invasive uroepithelial carcinoma are mostly treated with urethral bladder tumor electrodessication, and postoperative treatment with bladder instillation can prevent recurrence of the disease, which usually does not threaten the patient’s life. On the other hand, muscular invasive uroepithelial cancer, which has a poorer prognosis, requires radical cystectomy and pelvic lymph node dissection and other treatments, which can prolong the survival period and improve the quality of life of patients to a certain extent. Through early detection, early diagnosis and early treatment, patients with bladder cancer can improve the prognosis of the disease and reduce the adverse effects, and many patients can be cured, so it is recommended that patients actively undergo regular treatment.
