Your story is so similar to my 75 yr old husbands. First he did the laser therapy, it worked, but cancer was back the next visit. Then Jelmyto for the 6 treatments in 6 weeks. It did not work. Then he had his kidney removed and is now doing Keytruda infusions every 21 days. He had Signaterra blood test which showed cancer markers, so this week will have a PET SCAN to see where it is. My husband looks great and feels good, except a little more tired... he's currently helping get ready for a St. Patrick's Day party! Now he's being referred to a bladder oncologist for review. It's been a roller coaster ride since 2023 and we just keep on praying and playing. Best of luck!
