I'm 41 years old. Recieved a diagnosis of prostate CA in Nov 2005. PSA of 2.81 and a Gleason of 3 + 4. I have been scheduled to have Open surgery with Dr Carl Olson at Columbia University in New York City on 1/23/06 (a week from Monday). However, I just came accross Dr Ash Tewari at Cornell in NYC who does robotics. Dr. Tewari claims to have only a 2% positive margin rate. He has performed over 1200 of these. Dr Olson has been doing open Surgery for 25 years. - I'm not sure who to go with? Any thoughts?
