I had a nodule that was 1cm x 6mm. I had this removed surgically to be biopsied because I was a high risk due to my smoking history. I am 43 and smoked for 20 years. I have not had a butt in 27 days
(since my surgery).
The nodule was benign and it was worth every minute of pain and discomfort because now I can sleep at night, I know I will be around for my kids, and I know I do not have lung cancer.
I would think it was an option at any size to have surgery. Why wait until it grows!!
