Sorry to hear this. I don't want to sound pessimistic, but as far I know, cancer treatment is heck of expensive in US, that's the reason most insurance also don't even cover it.

I would recommend your friend to contact social service department of any cancer center and try to collect as much information as possible. I am pretty sure if you show duck face to some social worker, they will give you most information and also hook you with some oncologist who will tell all avaiable options and may be cost associated with it.

And my sincere suggestion is go beyond that, and have appointment with oncologist , have him see all reports and make final decision based on their recommendation.
