@michellep I've continued my research, and came across (sorry, not sure where, now) someone who said that when multiple nodules are found it's usually consistent with an inflammatory process, rather than cancer. (This was from a doctor, not chatroom). I bet it's from your pneumonia, but {{hugs}} I know how scary that must be for you.
@Fran, take them up on the offer to see the Oncologist. 1cm is the perfect size to get a diagnosis and begin treatment (if necessary). At the very least, "peace of mind" is invaluable
