Financial struggles for stage 4 throat cancer

My dad was diagnosed with stage 4 throat cancer. He is no longer able to work. Until this, I have never seen anything stop this man. He's been the closest thing to a superhero I could've ever imagined. For months I have seen his health steadily decline. I'd be lying if I said I wasnt scared, I'm down right terrified at the thought of losing my dad. We have family and friends who have beaten this. With modern medicine and his sheer stubbornness, I know he will to. We are staying positive, that's all we can do. Any help is appreciated, as anyone who knows about dealing with cancer, it takes a huge financial strain on the family. Please help however you can. Thank you in advance
