Cancer Survivors Network

I've been on the breast cancer board many times since my diagnosis this past April and received a lot of help and encouragement there. Now, out of the blue my dad has received a diagnosis of lung cancer that has metastasized to his brain. He had a clean bill of health in the spring, complete with a CT scan so this has all come about since then. He was bowling and golfing two weeks ago! He has had no pain, I forced him to go to the dr. when he started having trouble walking and then he began slurring a little. I suspected stroke of some type and can't believe he's dealing with cancer. The spot on his lung is fairly small and has not been biopsied yet (tomorrow). It looks like there may also be some liver involvement. I know this is very bleak but he's already shown improvement since beginning steroids and radiation last week. (His first day of radiation was the first day I didn't receive it in 6 weeks). I have to start a second course of chemo in about two weeks and am concerned that I won't be able to give him the care he needs. Any info you can give me will be greatly appreciated, thank you all.
