Sorry to hear your disturbing news. My Father has secondry liver cancer which came from the bowel and is now in the stomach. When we first got his diagnosis I did so much research. I also read an interesting article about a lady who had had bowel cancer, had the operation then was treated with pioneering treatment for the liver tumors, it microwaves the tumor away, there are lots of restrictions though. Think depending on how many masses there are in the liver. Unfortunately my Father was not eligible but the Surgeon still took the time to look over my Fathers scan to see if anything was possible. I know I have left no stone un turned in an attempt to cure my wonderful Father.
This specialist is in England , not sure if I can mention his name. I know you are probably in America but I am sure a specialist in America is using this specialist treatment. Its worth taking a look. Just search for "my tumor was microwaved"( think it was in the Dail Mail Newspaper , I know it sounds weird but it has been successful. The lady was about 68 and has had secondry liver cancer too.
Good luck and don't give up.
My prayers are with you
Gail (England)
