You know, even if you do have emphysema, you're doing the right thing by quitting smoking. This will allow your lungs to heal and for the cilia (little hairs) to become mobile again, so they can sweep away the junk in your lungs. Cigarette smoke temporarily immobilizes them. Secondly, the progression of the lung disease is slowed down by not smoking, so you can look forward to more healthier years, then if you were smoking.
The nurse didn't diagnose me, she is just the one that told me. It is handwritten on my ct scan that I have copd.
I would get a repeat CT scan of your entire lungs and do lung function tests. You can't diagnose based on a CT scans that just sees the tips of your lungs. A specialist or GP really should do the diagnosing, not a nurse. If you don't have any symptoms or breathing difficulties, it be nothing or in the early stages of something. But quitting smoking is a really good idea. Healthier for you, more money in your pocket and better for your kids. You're also giving them a good example to follow.
