@fotula -- Hi. My wife has them too.

The goal of her treatment is to ensure they're not changing... so she gets yearly CT scans that provide good information on their current status. Depending on the type / status of the nodules, the scans may be ordered more frequently.

Don't know if you are / were a smoker. But it's certainly recommended that you not smoke (cigs or anything else), and avoid environments harmful to your lungs (second-hand smoke, or any other noxious fumes).

Good luck!
