You are at a center of excellence- MSK and are in good hands! Regarding the tumor size, did you mean cm instead of mm? Either way, that’s a great size for your discovery to have been made. How did it come about may I ask?
Also, as someone who quit smoking at 34 years old, (many years ago), you’re going to get through your surgery and recovery better if you could put that habit to rest. Good luck with that, but you can do it. My husband is almost 2 months post smoking now as he got a very bad case of pneumonia recently; you can do it!
