Definition of Lung Nodules. A lung nodule is defined as a âspotâ on the lung that is three centimeters (about 1.5 inches) in diameter or less. If an abnormality is seen on an x-ray of the lungs that is larger than three centimeters, it is considered a âlung massâ instead of a nodule and is more likely to be cancerous.
