I believe that a doctor can sometimes see a tumor in the bladder, and might have a pretty good idea if it is cancerous or not by its appearance, but for definite proof a biopsy is likely necessary. It is also possible they might be able to get that information from looking for and at any cells that end up in the urine, but I have never heard of that being done.

Can someone be kind enough to tell me if a doctor can tell if someone has cancer while doing a scope ina bladder?
Doesn't there have to be a biopsy done?
