Should i be concerned? ct scan shows spiculated nodular nodule left upper lobe measures 10 x 7 mm. could represent a small lung neoplasm but is surrounded by clustered micronodularity, raising the possibility for a focus of infection or inflamation?

More information is required. A virtual consult with Health tap is available. Discuss a risk calculation based on your smoking and family history, as well as the features of nodules and other factors. A PET scan may further characterize the malignancy risk

Well, I do not have access to the actual films. It is small (1cm or 10 mm is largest part measured.) He is concerned about the possibility of cancer, or possibly infection. I expect he will likely ask for a biopsy of the tissue. Some places also do PET CT scan, which sometimes can determine if area is likely to be cancer. Ultimately you will need obtain tissue from lesion examined.
