Years ago, my mom went to the Cancer Treatment Center of America in Tulsa (although we live in Florida). I recall talking to a receptioninst there that said because they were a not-for-profit church based center they often took non-paying patients. The founder of the center was a man whose mother died because she could not get treatment because she could not afford it. He decided that should never happen to anyone...they pay for travel for the patient as well as for a companion. The Center is adjacent to a large "hotel" which is owned by the center. My mom would go for a week every month. It was like living in a dorm. Very comprehensive.
Give them a call...
