Susan, I am two weeks past my 6 week BCG treatments. I know how you feel...I was terrified. Turned out it was very easy. The treatments themselves took about 10 minutes and were very tolerable. Afterwards, for that afternoon, I had burning and urgency and that was it. The last week I had a lot of fatigue, but that happens to me anyway and may not have been the BCG.
If you read carefully the information on this web site, you will see that bladder cancer is very treatable. For resistent papillary or CIS, BCG is the first line of defense. Even if that doesn't work, there are other options that are very successful.
Good luck to you and keep "hanging out" with us on this forum....the people here have been there, done that and are a great resource.
