I just got the copy of my PET/CT report in the mail. I knew I had some sort of a blockage to the right upper lobe from my last bronchoscopy. This PET/CT states that there has been an interval development (which I understand means during the time between this scan and the last one) of right apex (the uppermost segment of the upper lobe) atelectasis (collapse) / fibrosis (scarring).
Ok. Hopefully I'm learning the language correctly. So, since my last scan, presumably because of the blockage, the uppermost segment of my right upper lobe has deflated and developed some tissue that looks like radiation fibrosis (per the report) but isn't, since I haven't had any radiation for about a year and a half.
The questions are:
1.) Can I assume that this blockage is the source of my shortness of breath? It is just one little segment of one of three lobes. Doesn't seem like much, but I am huffing and puffing after a flight of stairs.
2.) I know that the tumor is the cause of the blockage. Can I also assume that the atelectasis/fibrosis is not likely to be reversible? Or would increasing my activity and perhaps using a spirometer help to re-inflate and restore this segment of lung?
3.) I hate the idea that a chunk of my lung, how ever small, is now useless and deteriorating. So long as there is a blood supply to the tissue there will not be necrosis, right?
Thank for your continued indulgence,
