Help with Cancer medical cost.

Here we are again with a new year and the co-pays start all over again . I had originally just figured I'd stop going to doctors. But, I don't think that's going to happen at this point. I'm supposed to go to Iowa City but haven't heard from them as far as an appointment. Everything is up in the air right now. It's best I keep seeing the doctors. I don't know what my costs will be at Iowa City cancer center. I'm sure it won't be free. Any help is so appreciated! Thanks so much
