Hi Amy - I am a 3 time survivor of bladder cancer and after the 3rd operation, underwent BCG treatments. I, too, was scared - but it turned out to not be that big of a deal. Yes, there was some pain when urinating for some hours after the initial (and subsequent)void - but that goes away. I learned to take a pain reliever about 15-20 minutes before the end of the 2-hour waiting period so it could start to take affect. And then used it every 4 hours when needed. The process itself of inserting the BCG is very quick and pretty painless. It is right about 2 years now since I started my first full BCG treatments (after the 3rd surgery) and I had a follow-up set of 3 treatments ending last week (have done a total of 13 in all). I don't go back for the next cysto for 6 months - but last month was the first time I have made it passed the 2 year mark without the cancer showing back up. I have to credit that to the BCG, but who knows. Hope this helps a little - I got some good feedback before I had it done the first time (helped me to actually decide to do it). And if it helps any, I was serving as a missionary in Bolivia (poorest country in SA) and had the last surgery and my initial BCG treatments done there! John
