Mike,
You can never ever predict what will happen. There are no certains in life. Focus on your treatments and on getting well again. It is okay to be scared out of your skin. I kinow I am, especially as the surgery date grows closer (only 2 days now).My husband has a big hill to climb. But we will climb it and we will get through it. That's what we do. And I know you will too. So...Take a deep breath and say a prayer (if you are so inclined) and we will walk this journey together, all of us are here for you and each other.
Good Luck and God Bless
