Star,
DO NOT PAY ATTENTION TO STATISTICS! According to the "statistics" I died 3 months ago (or longer). They are old, out of date and mean very little today. As long as your Dad is breathing there is hope! SO many things have changed. I was dx'd with sclc last year. Had chemo and went in to remission, had pci and came out of remission with mets to lymph and liver and have been on a new round of chemo since but I AM STILL HERE! I enjoy every day I have and live each day as if it is a gift (which it is). There is treatment for your Dad if it is what he wants.
You will be in my prayers,
MO
