nodules found waiting on another ct (Worried)

I had a 64-slice Duel Source MDCT coronary ct scan with contrast which showed my heart to be in great condition however they found multiple nodules on my lungs during the scan. I have since seen a pulmanologist but he didn't say much other then he needed me to have another ct and that I need to try to get the actual scan and not just the report. Anyhow I am scheduled for another ct scan in Dec but until then I would like to know what these nodules likely mean. Here is what the report says.

Extra -Cardiac findings: The visulaized lungs revealed 2 discrete 4 mm nodules in the right upper lobe along the fissure, along with a 2 mm nodule in the left lower lobe along the fissure. The mediastinum is normal. The pulmonary arteries are normal. The visualized thoracic aorta is normal.

How often are these boards actually looked at by doctors? I am just curious.
