RE:RE:RE:RE:Let me try again.....Thanks for your insight CancerSlayer, my non medical brain can't understand if this treatment is done correctly and produces a CR in a patient then how does the cancer return giving that person a NR. In my way of thinking cancer can only return because the bladder wasn't filled to maximum and remained undetectable within a fold thereby producing a false CR is this plausible? Please point out possibilities that have caused a CR to flip into a NR rather than a IR.
