Frank,
As Im sure you already know, surgery is the best chance a person with Cancer can have. My dad had his surgery in June. He also is a lifelong smoker, and moderate drinker. Now, 2 months after surgery, hes starting to feel pretty good. Its been a rough 2 months, but things seem to be calming down. I think if you and your mom have the right additude about this, SHE CAN BEAT IT! I think anyone offered surgery should at least really think about it, I mean, you never know what may come out of it... my dad is cancer free right now! I hope this helps you somehow!
