Hi, dear I have gone through your question. I can understand your concern. She has urinary bladder cancer of stage 4. So surgery is not possible at this stage. Treatment options are chemotherapy and radiotherapy. BCG is also one option. Despite of treatment prognosis remains poor. Life expectancy is not good . Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic.
