By all conventional criteria, these nodules are small and thus highly likely to be benign in every sense of the word. While the presence of an irregular surface of a much larger, singular nodule would be worrisome for possible malignancy, the surface “irregularity” of multiple small nodules, of this size, does not at all have that same significance. Both you and your doctors should be reassured by the fact that there have been no changes in the size or configuration of these nodules over a 3 month period, the recommendation that the CT Scan be repeated in 6 months is sound. You may want to check with your doctors regarding the wheezing.
Good luck
Forgot to mention that I have noticed a mild wheezing in the last 6-8 weeks as well. Thanks.
