I am new here looking for advice if this is a right place.
Annual CT scans have identified a stable right upper lobe Ground Glass Nodule (GGN) measuring 5 x 5 mm with a small arterial branch courses to the center of the opacity for the past three years, which may represent an area of Atypical Adenomatous Hyperplasia (AAH). This nonspecific Ground Glass Opacity (GGO) was incidentally found in a CT scan three years ago for other medical reason. No significant growth or change has been foubd in CT scan reports since then. I feel sorry to myself that I did not pay any attention to the GGN/GGO/AAH in the past until my Dr. suggests to monitor it in annual base recently (Aug. 2020). I think I may need to make appointment with my PCP and a specialist to clear some questions burning in my mind. I am not even sure if it is a pure GGO or mixed GGO since there is a small arterial branch courses to the center of the opacity. But I would like to know what kind of specialist doctor I should looking for before seeing my PCP. It is greatly appreciated if you could share similar experiences and educational information. Thank you very much in advance for your time. Good luck to everyone here.
