Wow, you have really been through the wringer with medical issues. To answer your question, we found that it was a good thing that we had a Mayo visit for an executive physical scheduled for my husband shortly after the local urologist said bladder was clear. He had looked at CT scan and done cystoscopy, had ignored a positive FISH test and the cytology of highly aggressive urothelial cell carcinoma. At Mayo they saw the bladder tumor on the CT scan read as negative by local radiologist and urologist. Mistakes do happen. Requesting a second opinion is always smart and can be done virtually nowadays.
