If she lives in the US she should apply for medicaid. My brother was in the same boat when he was diagnosed with stage 4 cancer of the tongue. He couldn't work. Fortunately he received care through a state public university hospital and was put on medicaid. So he had no medical bills to pay. Her doctor should put her in touch with a social worker. If that hasn't happened yet, call and ask who you need to speak to. Are you her medical advocate?
