Gcirillo,
Welcome here.
First, understand I'm not a doctor but have 13+ years surviving late stage NSC Squamous Cell LC so I've encountered my share of CT scans and reports.
My recollection from discussion with other survivors is numerous small nodules that are metastatic often result from a larger primary tumor. But, I've also know folks who are diagnosed with many small nodules and after a period of growth have biopsies that show metastatic lung cancer. Most of your nodules are 2 mm and that is very small. Even 3 and 4 mm are very small and normally associated with a lung infection or pneumonia. Your diagnosis radiologist's indication of "post-infectious or inflammatory" and the 3 month followup CT appears to me to be a good call. Moreover, if it were me, I'd have for CT scans every year (because of your reported history and this finding) to keep track of things.
So I agree with your radiologist for a 3 month followup CT scan and add the recommendation of annual scans to keep track of the situation. Hope the future scan shows no nodules. By the way, have you had a recent bad chest cold or lung infection?
Stay the course.
Tom
