Barry,
So sorry you are joining our group, but this is definitely the place to come for answers and support!
I can only say we have many many +5 year survivors on this site. At 66, you are still a young man and have the added bonus of being healthy! Each of us has to make the decision about how to fight and how hard to fight. However, I think you will hear from others who will reply, that their lives, although changed, are well worth the battle.
Best wishes in your journey. You will find many friends here.
Jennifer
