Hi, I had a 1.2 cm lepidic-predominant adeno removed 18 months ago. Latest scan newly identified a 4 mm GGO that upon comparison to prior scans has been there since 2010 with minimal change. The report said due to persistence it was suspicious for AAH or AIS and recommended follow-up imaging "at a minimum." To me, whatever it is, it is pretty darn indolent. Is this just a radiologist being very cautious by implying that I might consider doing something more than watch and wait, given the history of prior malignancy? I can't imagine what alternative I have given the small size.
Also, I also had "a number of 2 mm nonspecific nodules in both lungs." No mention if they were present on prior scans. My initial reaction is that everyone probably has tiny spots and only this radiologist chose to point them out, but, again, given my history, how much should I consider that this could be more AIS in its infancy?
As always, thank you.
