I, too, have bladder cancer and am presently going through immunotherapy, but just one treatment so far, with many weekly sessions to follow. The Mayo Clinic was unable to treat my cancer, so I am using a local cancer/hematology clinic. At age 82, I have little hope for long-term survival and will not continue with the treatments if the side effects are too severe.

I wish your sister the best of luck. She is in my prayers!
