Hi: I think that most familys these days have cancer in the family. My family has a history of cancer. But family history of cancer is just an indication of risk. The important thing now is that the nodules are teeny teeny tiny and the only thing you can do now is wait. I wish my nodule was small, but it is not and I ain't waitin. Mine is 2.2 cm...way too big. I know it is hard to wait, but really, many people have these little nodules and never know about them because they have never got a ct scan.
I agree with Donna G that they are probably from the pneumonia.
I chuckled at your comment about not beeing able to get rid of the smiley face. I think it is a sign too.
