I too had robotic lung surgery in February of this year. The top lobe of my right lung was removed. Fortunately cancer was stage 1 and all lymph nodes tested were negative. I exercise twice a week but thinking I need to do more. I'm guessing that will help with shortness of breath I sometimes get. High humidity definitely doesn't seem to be helping. I also am experiencing a cough at times that makes me nervous. Do other folks have a cough too? Hoping it will eventually go away
