get a 2nd and 3rd opinion... What oncology center is he going to? I like the idea of the recordings of his voice. I would like to have some of those of my dad now although I still hear his voice in my head and he passed 3 years ago. I wish I could say that the death will get easier with time but it doesn't. You just don't think of it as much but that doesn't mean that the pain isn't just as fresh when you do.
Don't be afraid of chemo. they've come a long way since years ago. They now give you meds to help with the sickness and you don't always loose your hair (I didn't.... in my defense the hair on my head was gone long ago) Hearing the word cancer can quickly take much out of you and you feel defeated, he needs you to push to fight it and help him stay positive. Try to take trips in between treatments and make sure to do things with him. Don't put them off until next weekend or you will soon get the call and be filled with tons of regret. The most important thing is to make sure that he never feels alone in the fight. It's always WE have this... WE will beat it. the feeling of defeat and loneliness with cancer is the hardest part of the battle. If you keep his moral up, win or loose, his quality of life will be the best it can be. Also prepare yourself now, cry, read up on it... this will be an ugly battle and watching him go through this will put you to the limits of what you can emotionally handle. PM me if you have any questions or need someone to talk to.
