Hi Sue, thank you for your reply. Your description of ground glass density sounds less ominous than some of what I have read and gives me a little hope. I guess it puzzles me because I haven't had any colds, coughs, allergies or any respiratory issues whatsoever in a very very long time. The last thing I had was a mild case of covid back in August of last year so about a year ago now. Could an illness that long ago still show up as GG nodules a year later? I had the CT scan because I am a former smoker, just barely meeting the new updated criteria for LDCT annual screening for lung cancer. Age 52, 22 pack year history, 15 years since quitting. Since I had the heart ct scan at age 50, my dr. said that if there were any pulmonary nodules they would have seen them then. I am not sure why at 51 I didn't get the lung screen but this year at 52 decided it was time to start. I had it done Friday last week and my head is still spinning. My dad passed away from NSCLC Stage IIIb Diagnosed at age 68 and succumbed to it only 10 months later. He was also a former smoker with a lot longer pack history than myself but had also been quit 20 years by the time he was diagnosed. I understand first hand how devastating this illness can be. To say I've suffered from PTSD from his experience would be an understatement. I am constantly working on my diet and exercise and do fairly well but always room for improvement. 🙂 Thank you again for your reply.
