My Daddy's cancer recovery

My daddy, Melvin Gregg, found out he has stage 4 throat cancer. He does have insurance, but where he will be out of work to go through chemotherapy I'm afraid he won't be able to afford his insurance deductible and living expenses. One doctor said he has a 70% chance of survival, but it will be an extremely rough time going through these treatments. I want to help him in any way I can. I mean, everyone has a spare dollar, right? Thank you in advance to anyone who chooses to help.
