How long is the survival time of bladder cancer without treatment is to be determined according to the malignant degree of the tumor, its stage and whether it is metastatic or not. The survival time generally ranges from half a year to five years. For bladder cancer with single small tumor disc, i.e. non-muscle invasive bladder cancer, the survival time of patients without treatment is about three to five years. If bladder cancer occurs in the middle to late stage, i.e., bladder cancer that has infiltrated into the muscle layer but has not metastasized, the survival time is probably less than two years. If the bladder cancer occurs in the advanced stage when metastasis occurs, the survival time is about 6 months. Although bladder cancer has a greater degree of malignancy, it is still hoped that patients can keep a good mindset and treat it positively. Patients need early detection and early treatment, and the earlier the treatment, the better the effect.
