Were any lymph nodes removed and checked during your surgery? My husband had this done at Mayo Clinic and 1 of 29 nodes removed was positive for tumor. It was graded per those results. As a very aggressive tumor, it continued to recur in the bladder until total cystectomy was done. Recurrence was resistant to BCG and Keytruda, and he chose radical cystectomy with neobladder to try for a cure. So far so good.
