Hi again Kellie,
Thank you for the quick reply. It does sound like cyberknife, as I know they implant gold seeds into the tumors for the cyberknife beams to track to. I'm sorry to hear your dad now has more tumors and that he's not as open to discussing it all as you'd like. I'm actually leaning more towards the liver resection just because if my entire left lobe is removed, as the surgeon is proposing, it would take care of any other microscopic cancers that may be there, as well. He just wants to do a wedge resection on the right lobe (otherwise my whole liver would be gone!) Supposedly, the liver does regenerate itself again fairly quickly. I will still look more into the cyberknife. Thanks for sharing your info. Take care!
