My dad had rectal cancer 3 years ago and it has now spread to the liver. Doctors were going to cut off the parts of the liver with the tumors and freeze the tumors they couldn't cut off. They couldn't do it because they said my dad has cirrhosis of the liver and more tumors than they thought. Now we are going to see a doctor that does the chemo-ablation and another doctor that does the injection of beads into the liver. I don't know anything about these procedures. Any input would be great.
