John,
Hello and welcome. As we often say "the club that no one wants to join"
I can't answer your questions. Haven't had that kind of surgery myself. But someone will come along that can answer.
As to the odds. They seem to me a lot like statistics. Which if you use the search you will find we have had many discussions on this topic. Odds are like statistics in that everyone is different and their response to treatment is different.
Yes I believe in planning, but I also believe in being positive about certain areas in my life. This is one that all of us try not to let consume our lives. (even though it is such a big part of it)
Guess what I am saying is being prepared is a good thing but I can't believe anyone will come on this board and give you odds. From what you have told us so far you have a good outlook to your treatment. (caught early is very important)
We'll be here to answer anything we can be of help with or just listen to you vent if needed.
Good luck and take care,
Dinah
