My hubby was diagnosed with bladder cancer in 2010 and had BCG treatments a few times and the dr. at Mayo said that was the last BCG treatment he could have and if it didn’t work he would do something else. He went into remission and 2017 cancer cells showed up and he was on maintenance treatment. He had his treatments in Athens, GA but we went down to Mayo for his cystoscopy. This year he said he just couldn’t travel any more as he also has COPD and 2017 had to have an operation lung, then last January they thought he had the flu and stayed in hospital 15 days. I talked him into having antibody testing when it became available and he came back positive. Now he still has cancer cells, and he had a cystoscopy done in Athens, then a cat scan, and today he went to the dr. to see what the cat scan showed and it didn’t show that anything was wrong. The dr. told him to have his 3 maintenance BCG treatments which start in November then another cystoscopy, and of course they will send his urine to a lab to see if the cancer cells are still there. If they are they want to do an exploratory on his Kidneys and he doesn’t want that. I was reading a post where someone had to have a guided liver biopsy. Can’t a guided Kidney be done instead of an exploratory. He is not in good condition to have another operation as he’s on oxygen which doesn’t appear to help him, uses a chair I bought him to ride in when we go to large stores. By December he will be going on 83, so wonder if anyone can give advice whether a guided Kidney biopsy can be done. If I’m in the wrong area for this question please let me know. Thank you. I know he’s nervous so that’s why I want to research this.
