V.T.
She will not qualify for life insurance. It sounds harsh, but insurance companies need a return on their investment. They are banking on people paying more in premiums over the years than they will actually pay out. If she is ill the chances of her paying more to them than they will pay out upon her death are slim and they will not take that chance.
As for health insurance, I don't think she will get it either. My FIL was treated at NIH in Bethesda for free. It maybe worth looking into getting into NIH, maybe her doctors can recommend it. I don't know how my FIL got in, so I can't help you there. He got top of the line care at NIH, but they did use his case for research purposes since he did have a rare form of cancer.
