Thanks to all of you! To answer a few questions:
Yes, they are all low grade tumors, thankfully. BCG hasn't been administered for a while, as it's not working for him. They do administer another form of chemo (directly into the bladder) just after the surgery, which seems to be working a bit better.
Recurrences range; it's been a year this past time, and he has surgery scheduled for Monday morning. Sometimes it's 3 or six months, and I believe we had one stretch of something like 18 months. The current tumor was <3 mm in size when the urologist spotted it at the last cystoscopy, so we're staying on top of things. His urologist is considered to be top-notch, and we are actually switching insurance plans in order to remain with him (my insurance coverage would be better but I've been on a different plan.)
Yes, it's life in three month increments and we just try to live our lives normally in-between surgeries and cystoscopies. My husband has come to this site and started to read up, but I'm not sure if he'll get into the interactive thing.
Again, thanks for the support. It means a lot to me.
