Two weeks ago I had my second cysto since my Mitomycin treatment in April. My doctor stated that he found no new tumors and the areas of the last two TURBS and biopsies looked fine. Part of my Urologist routine is that he orders a FISH test one week prior to the cysto. Then the day of the cysto he does another routine urinalysis. He stated that the FISH showed squamous cells in the specimen. After the cysto he had me stay around long enough that I could give him another specimen. My questions is does the existence of squamous cell in the urine indicate anything. When I asked him he stated that they were pre-cancerous cells and might not indicate anything, but he wanted to keep a close watch. I guess I could do a search on the internet, but I have found that our forum is great in answering questions too. Any information would be appreciated. Thanks, Chuck
