Thanks for your reply. My next cystoscopy will be a blue light with TURBT if needed. I'm sure my Urologist is not a oncology urologist but very well trusted in his community.

In addition to all this, I have a 2nd opinion scheduled with Memorial Sloan Kettering on 11/13 to confirm the findings and possible treatment options. In my honest opinion, if I am assured that there is/are no cancer present I will move ahead with the Diverticulectomy. Depending on the 2nd opinion of course, Even though this is a second recurrence for me, it feels all very new to me.
