It could be a number of things, You need to follow up w/a pulmonologist. I too, have these and are doing follow up scans every 6 months to watch for growth. How many do you have and how big are they? Mine are 3-7mm and I have 15 nodules so far, started with 10 when found. PLease keep me informed w/ur progress.

I too am having multiple nodules showing up on every CT I have.  Within 5 months I have a new 7.5 mm ground glass nodule and was told to get a pneumovac (pneumonia) shot as well as getting another CT in December, which is now within 3 months of last CT.  I have another one on my right 2nd rib that is 8mm and ground glass also with multiple smaller ones in both lungs.  I just don't feel like I am getting any answers and also feel like I should have a biopsy.  Any suggestions, any idea what exactly Ground Glass Nodules are and should I be concerned if a new one shows up 5 months after PET scan?
