Low-grade bladder cancer is not benign, it is a malignant tumor in itself, only that the degree of malignancy is lower compared to high-grade bladder cancer, and the relative treatment effect as well as survival time are better. Bladder cancer is a kind of uroepithelial cancer, no matter it is low-grade or high-grade bladder cancer, all of them are malignant tumors. The treatment is directly related to the clinical staging, early detection, early diagnosis and early treatment, and the bladder cancer with early staging is better in controlling the condition. After surgery, chemotherapy and other reasonable treatments, the prognosis of early-staged bladder cancer is relatively good, and the chance of recurrence is not high, but cystoscopy review is still needed. When low-grade bladder cancer is found in clinic, it is recommended to consult the urology department of regular hospitals.
