I know how you feel, I when the first time for nine years and sort of went to the scope thinking that all was good and then I saw the growth. But that is why they do the scope.
As long as they have gotten to early all should be alright. Mine came back three times so far and I have the scope every two years now and hope for the best.
Are you getting BCG treatment or did you get them before?
Take care and all of the best.
