Lung nodules in 3 lobes of smoker. 9mm does not enhance ; no calcificat. does this suggest small cell or large cell cancer? needle biopsy scheduled.

Lung nodules: Clearly in face of smoking a worrisome finding. Biopsy appropriate.

Could be benign.: The 3 nonenhancing lesions that are noncalcified could be benign or malignant. If malignant, could be small or large cell or could be spread there from another site(metastatic).

-: Hard to predict based on radiographic findings; should wait for results of biopsy.
