The biggest learning I have had from this is anyone can beat the odds, the odds are only an average, get the best doctors which it seems you had with the places you've been, take the most aggressive treatment (you don't want to take any chances). The treatment process is tough but not unbearable. The side effects usually a minimal and in my case and others are hardly noticable or you get use to them. Your are taking the right approach to get several options and listen to others who have been through it which I learned more and was reasurred more from the past advocates who have been through it. Like the old saying you can't beat experience.
