1 cm lung cancer tumor with COPD & emphysema: Anxious

Hi: I am 75 years old and recently diagnosed with emphysema copd and 1 cm nodule that grew 1mm since last year and solidified. I had a pet scan that proved positive for cancer.
My pcp is optimistic that a VATS will take care of the growth as he has determined the copd and emphysema are mild. I typically walk 2 miles mostly up hill almost everyday and am able to breathe quite easily and do all that I need to do.
I am hopefully having a video visit with UPMC surgeon who is highly respected

I am experiencing extreme general anxiety and have been reading many of the comments on here and so appreciate all of you writing about your concerns,success and troubles.

Thank you
