My oncologist doesn't seem to want any surgery performed because he says it will create "too much tissue loss," I'm assuming because I've had extensive radiation in the past and they're concerned also about fibrosis as a result of that. I've never gotten a clear answer. I had a pulmonary finction test about five years ago and the results showed some slight COPD (yes, I was a previous smoker), but I'm on the ellipticals at the gym for 25 minutes 3 days a week with no difficulty. We have talked about ablation, but my radiologist has said that they've seen mixed results with it. I'm meeting with my oncologist on Wednesday morning, I'm going to try and get more information.
