My urologist, at a major medical (teaching and research) center, will do blue light cysto after my next round of 3 BCG treatments. He says it’s much better for seeing CIS tumors, which is what I had prior to TURBT. He also says an advantage of being at this big hospital is that I won’t have to worry about a BCG shortage compromising my treatment. Best wishes to you. Hope your talk with the doctor goes well and you find comfort in the answers you get.
