It’s not uncommon that they wait even though all you want is for them to remove before it can cause you trouble.. it’s very normal to feel this way…I also went through 3 years of routine ct scans before they could determine what it was, before that happened they said it was too early to make a diagnosis… on a happier note, you are being looked after very early on and this is a big advantage with the lungs, I learned that the reason they have poor outcome with the lungs is because it’s found too late. I know it’s hard to relax but your in a good place and also nothing has been determined so it might just be a nodule and they are normal and not always a problem
