Definitely a frightening time to be told of a tumor in your lung. When I was diagnosed I had absolutely no symptoms ... the tumor was considered an 'accidental discovery' in an x-ray of my elbow (go figure!).

I had a robot-assisted partial lobectomy a month ago, which sounds like what you'll be having. The recovery wasn't too bad -- only one night in hospital. The pain was manageable. Breathing for the first week or so was strange ... short, shallow breaths (kind of like a guppy fish) while my body adjusted to half a lung. But getting up and walking around the house a bit the first week and then taking short walks outside as I recovered really helped. One month in I'm able to walk my usual 2 miles every morning and breathing is 'normal',, as much as it can be.

You are in good hands -- human and robotic. Sending you positive, healing thoughts.
