Sarge, that's really terrible. I lost my baby sister in January to cancer, at the age of 42. 5 weeks after her birthday actually. Same day the community lost Dave. Brother, I've been to 4 funerals since. My sister being the first. So i'll use what diplomatic leverage I have with the Divine Providence and pray that it makes a difference for you and yours.
If you want to, you can contact the Cancer Treatment Centers of America, and a few other places that do things outside the box, from the standard treatments the rest of the medical world uses.
Good luck with this! Keep the spirits up, even when it seem like it's the worst.
