Low-grade bladder tumors may metastasize, and timely resection of the tumor lesion is recommended, and treatments such as bladder perfusion chemotherapy are also needed for high-risk staging. Low-grade bladder tumors include non-invasive papillary uroepithelial carcinoma, low malignant potential papillary uroepithelial tumors, etc., which is one of the subtypes of malignant tumors with metastatic risk, and it is recommended that timely resection and treatment be carried out by surgery such as transurethral cystectomy of bladder tumors. For multiple, recurrent or large diameter low-grade bladder tumors, which are at higher risk, bladder perfusion chemotherapy and other treatments are needed along with surgical treatment, and commonly used drugs include gemcitabine, mitomycin C and other drugs. The above drugs need to be used under the guidance of clinicians and unauthorized use of drugs is prohibited; if you suspect that you have a bladder tumor, it is recommended that you go to the hospital in time.
