Non-small cell cancers include squamous cell carcinoma (tumor), adenocarcinoma and large cell carcinoma. Bronchioloalveolar cell is a subtype of adenocarcinoma and typically treated in a similar way.
Adenocarcinoma, the most common type of lung cancer, is usually located on the outer surface of the lungs (periphery) and can spread to lymph glands, the bloodstream and other organs. Squamous cell carcinoma may be found in the lining of the large bronchi (air passages) or in the periphery of the lung. Large cell carcinoma usually occurs in the periphery.

Small cell lung cancer usually develops in the central areas of the lung. It can spread aggressively and occurs almost exclusively in current or former smokers. This cell type has the strongest association with smoking. Read about small cell cancer treatment.
