Gut feeling. And I'm not kidding about this. I interviewed two surgeons before my surgery. The first one was too happy clappy about the surgery. I knew better than that. I mean, every time I had a scan, they were finding something else. This surgeon was an osteopathic physician. The second surgeon was very serious about the case in her demeanor from the get go. No joking, no smiling, just a PET scan. Miraculously, even with what turned out to be a Stage IIIc (10/16 nodes) diagnosis, the PET scan was clean. She removed the 5 tumors with clear margins. She has been practicing for over 25 years and is a Yale med graduate. I imagine in some fashion "reviews" are like how they are done in the business world. Remember, they can be solicited. Try to read your surgeon's face and demeanor, and write down the same questions for anyone you talk to, and see comparitively how they respond when they answer them.
