I have non small cell lung cancer in upper left lobe, stage 2. I have copd and failed Pulmonary Stress test. I am doing Pulmonary rehab trying to build my lungs up so I might be able to have surgery. I have been told I am high risk because of my lung function. It has been about six weeks and I am very concerned waiting to do surgery instead of starting chemo and radiation increases my chances of it spreading. Is it worth the chance of waiting to have surgery, which may not be possible.
