Rando,
Hey. 21 BCG treatments? I've had 12 and I don't think that my bladder would allow me another one. I have terrible urinary frequency, sometimes as often as every 15 minutes, but, so far I have not had the irritated places seen in the bladder. I go for a cysto next week, so there is always a chance he will see something different.
It does not surprise me that BCG could cause spots of bladder irritation, but, if it was me I think I would want one more doctor taking a look in there and concurring with your present doctor about these spots of irritation.
Just my opinion. Good luck.
Your BC friend,
Rosemary
