I too have a friend undergoing this bead treatment right now. His daughter is going to donate a portion of her liver to transplant.
This treatment worked better than anybody's wildest expectation, even the doctors were surprised. The whole tumor was gone. He was stage zero when they did the transplant.
The daughter will donate about 1/3 of her liver which will regenerate completely in a few months. Her dad will grow a complete liver in about the same amount of time. Amazing organ.
