Thank you for the responses. We are mostly concerned about the lack of consensus between doctors. My dad is an active person and having his bladder removed is a big decision. My dad spoke with another patient who had between stage 2 and 3 bladder muscle invasive cancer who opted not to have his bladder removed. His urologist was able to see the cancer clearly with a scope, which informed his decision not to remove the bladder and only continue infusions. My dad's urologist implies that the scope does not provide a clear enough view of the cancer.
