I'm so sorry.
I hope everything turns out.
Not to be an a**hole, but I just did a bunch of research for a speech I had to do. Unrefined virgin coconut oil showed in a 50 year study to have significant anti cancer properties. It also kills the aids virus, and helps in the same way with tons of other health problems. The dosages vary from 3-4 to 6-8 tablespoons/day. It really has significant immune boosting, antiviral, antifungal, anticancer properties.
I wish the best for your friend so that's why I passed this along.
My grandma was 78 and came back from lymph cancer, I think your friend has a great chance.
(((hugs))).
