I very much agree with Sauce... Andreas Morritz is very good in what he writes, he has even written a book on dealing with Cancer... search his name on Amazon.. or go to his website.
In addition, the China Study is also very informative about the action of protein intake (meat and dairy) which feeds cancer growth.
If your family member is eating a high protein intake, this will fuel the cancer growth. They can cut the fuel to the fire by stopping to eat meat and milk/cheese. Sounds extreme I know, but it will at least cut down the flame while you figure out a cure.
best wishes to you and your family...
put them on the healing thread too!
Love and healing from me...
