Need to follow up!: It is important to note the shape of these nodules. If the edges are irregular or " spiculated" that is more worrisome. Also, the pattern of calcifications is important as well. These nodules should be followed for stability for 2 years. If they change or enlarge, they should be biopsied or evaluated for malignancy. Follow the recommendations of the reading radiologist, or get 2nd opinion.

Need evaluation: He would need further evaluation. The fact that he is a former smoker, still gives him significant risk for lung cancer. I dont know the size of the 1st nodule- if possible, a core biopsy should be done to rule out malignancy. A pet scan also needs to be done if not been done in the past- although however, negative finding on the 2nd nodule will not rule out cancer completely due to its size.
