My dad was diagnosed in February of this year with squamous NSCLC. He completed 5 rounds of carbo/taxol but had to stop because of the toll it took on his body. The doctor said radiation wasn't an option, but from what I've read on this site, it looks like it is. What else can he do? Any suggestions on chemos or radiation therapies would be greatly appreciated.

Sorry to hear about your father. Unfortunately, I don't know much about squamous. I'd like to suggest going to cancergrace.org and asking the onc there what they might suggest. You should state your father's age and any health issues.
Good luck and take care, JC
