Lung cancer most commonly metastasizes to the brain, bones, liver, and adrenal glands. [14] Lung cancer can often appear as a solitary pulmonary nodule on a chest radiograph or CT scan.

Adenocarcinoma of the lung is the most common type of lung cancer, and like other forms of lung cancer, it is characterized by distinct cellular and molecular features. [1] It is classified as one of several non-small cell lung cancers (NSCLC), to distinguish it from small cell lung cancer which has a different behavior and prognosis.
