Multiple Ground Glass Lung Nodules

Hello all, I just had my first LDCT lung scan, age 52, former smoker. Quit 15 years ago age 37. The findings were shocking to me.
Nodule 1 - upper left lobe 7mm round, ground glass density, indistinct margin
Nodule 2 - middle right lobe 5-6mm round, part solid, indistinct margin
Nodule 3 - middle right lobe 4-5mm round, ground glass density, indistinct margin
Nodule 4 - lower left lobe 5-6mm round, ground glass density, indistinct margin.
According to the LUNGRADS category they list these as category 2 nodules and recommend follow up CT scan at 12 months. I feel like that is a long time to wait. I understand that many people have nodules and some just go away but I guess I am concerned because if this were an inflammatory process for me it would indicate recent illness. I have not been sick or had any cough or congestion in a very very long time. Does anyone have any experience with ground glass nodules that appeared suddenly and went away or stayed stable over a long time? Also, I had a CT scan for calcium scoring on my heart 2 years ago and on that report it clearly says NO SUSPICIOUS PULMONARY NODULES. So I wonder are these new and developed to this size already in 2 years? Or could it be perhaps they were missed or not visualized because it was a heart scan? So many questions and I do have an appointment with a pulmonologist on November 1st who can hopefully look at both of these scans and help me figure out what may be going on but I would really love to hear from as many of you as possible regarding lung nodules, ground glass nodules, and your experiences with them. I think it would help me feel not so alone and maybe help me to understand this a little better in my own mind until I can get more information from the pulmonologist. Thank you all!
