@marysmith83, Thanks for the additional details, it helps to understand what you are facing. It sounds like your doctor is working to identify the pathology of the largest nodule, that's good. All of the tests and scans are pieces of the puzzle, and the more information that you have the better they will be able to assess the next steps. Each of those pieces takes time. It will be a long month for you, and it will be best if you can try to find a way to distract yourself. I know, that's easier said than done. But try to find some good through doing the things that you enjoy.
Be assured that IF this is cancer (we don't know that yet), it seems to be small and contained, and there are many treatment options available today that didn't even exist 10 years ago. Lung cancer research is finally getting attention and making advancements. There are many people here on Mayo Connect that have been through this. We know it's not an easy time for you or those closest to you. Do you have support from family or friends?
