I'd love to attend but don't think I will be able to. Going to Dominican Republic next week for my son's wedding. I'm a business consultant so I don't really get too much control over my calendar because it kind of depends on when I have active client engagements (which I will have lasting through the event). I wish I could though!
I'd suggest at the very least, you get on the Sunday evening chats. Those are every week here on the site. I don't do those but other great folks do and I understand they are very helpful for people.
Don't wait to move forward on treatment. High grade cancer means high grade cancer. T1 means the very next step is muscle invasive and you don't want to get there. Good news is you did catch it before it got there. I originally had CIS but when it came back two years later it was muscle invasive. I already planned to get my bladder out if it came back at all so I just followed my plan. That was 3 and half years ago now and I'm cancer free.
You can start BCG AND schedule yourself for a 2nd opinion at the same time. You just want to be ABSOLUTELY POSITIVELY sure there is no progression beyond T1. T1 is invasive by some definitions but mostly invasive is defined as "muscle" invasive. The instant that happens you want the bladder out in the next week or so.
Some doctors would lean more toward RC when there are multiple T1 tumors. Just don't overestimate the value of keeping your bladder if it can kill you. Plenty of us here are doing fine (years and years later) without one.
No need to rush into it either. Study all you can but at least go to a top bc doctor for the 2nd opinion. Starting BCG isn't going to interfere if you later decide to just get it out. If you do wind up needing an RC, go to a top place with a doctor that does at LEAST 50 of the surgeries with your preferred diversion (neobladder, Indiana Pouch, ileal conduit) a year.
