Free Cancer Resources?

Does anyone know of any free resources for someone with stage 4 cancer? She has just been told that her insurance will no longer pay for any procedures, etc., and will henceforth have to pay $1400 per month for any insurance at all, plus co-payments which she cannot afford. Without some kind of medical help, even if only palliative, she doesn't have a chance. Any suggestions would be greatly appreciated. Thank you.
