Dear Harley4,
My daughter had cancer of an unknown primary which ended up in her liver.....she had an rfa and our radiologist gave us the same information about risks, etc. He ended up getting 85 percent of it and Amanda, my daughter, ended up staying in the hospital for three days instead of over night because of the pain she was in. She was young and healthy and strong when diagnosed with her cancer...the RFA was considered a success, and her oncologist gave her a break from chemo after the procedure was done.....within two months it had spread to other parts of her body, bones, kidney.....I am sure if we had the chance to do it all over we would because it gave us hope at a time where we desperately needed it......she had so much pain because it was such a large area of her liver...If your mom is strong enough I wouldn't hesitate to have it done..in our darkest hour we need to cling to the fact that there is always hope...My biggest regret is that they gave her a break from the chemo, but the bottom line is it wouldn't have made a difference with Amanda...unknown primary is terminal, and we were lucky we had her for the year we did after her diagnosis.....I wish you and your family good luck and healing.....
