Britt,
Wow! Not a good story.
The treatment all depends on what they found. There are stages and grades. If it was superficial (not into the muscle wall), there is typically a follow up of BCG done weekly for 6 weeks, and then maintenance doses after that at the 3 mo, 6 mo, 18 mo, etc.
The problem is that the BCG is instilled through a catheter into your bladder. If you have such a problem with prostate constriction, it may be worth seeing if the can do something surgically to releive that so that they can do the instillations.
You certainly do need follow up treatment. BCG can GREATLY reduce the chance of recurrence so it's important to check out.
If you can't get through the VA, then certainly get it somewhere.
Best of luck,
Mike
