I have an update on the cytogenetics. We don't have the full analysis back yet, but there is a test indication that Nancy's leukemia is an "inversion 16" genetic error, which would be 'acute myelomonocytic leukemia', or "M4" in the older FAB leukemia classification system.
This is one of the best possibilities, and has a good chance of successful treatment, if that is in fact what she has. Keep the faith. I'll let you know as soon as I know more.
