@theblindsquirl, My heart goes out to you and your family.  I truly hope that the progress continues and your wife continues to get better.
I know from first hand experience that you probably have suggestions coming "out of your ears" and this is probably just another know it all trying to put in his 2 censt worth.
A friend of mine recently had liver cancer and was told "Chemo is the only thing to help".  Knowing what is in the Chemo therapy she declined saying "if I am going to die, it won't be getting somebody wealthy".  Like you all she did the Vitamin C treatment and she had another "old home remedy" which was called "Black Salve" or "Blood Root".  It comes from a flowering plant that when the roots are broken the sap looks like blood.  I believe the place she got capsules from is in Australia called "chickety poo" or something like that.   Two years later, totally cancer free.  She continues a 1 capsule a month regimen just as a precaution.
Never give up, that is the main thing.  hundreds of years ago, people healed themselves as the doctors were to far away.  Hoping for the BEST, prayers sent your way!
Mike
