Scott’s cancer treatment

My dad was diagnosed with prostate cancer over a year ago. Unfortunately  after having his prostate removed there was still cancer and the levels continued to rise. He now has to do 8 weeks of radiation 5 days a week traveling over 2 hrs per day. My dad is a very simple man and never asks for anything. (Probably will not be happy I started this) Even after his insurance coverage he owes $600/week just for the treatment. This doesn’t include appointments, gas, etc.  I know this is going to be a heavy financial burden on them so any help would be greatly appreciated.
