Types of ResourcesLung nodules can be cancerous (malignant), though most lung nodules are noncancerous (benign). Lung nodules (small masses of tissue in the lung) are quite common. They appear as round, white shadows on a chest X-ray or computerized tomography (CT) scan. Noncancerous lung nodules are often caused by previous infections.
