Non-Small Cell Lung Cancer (NSCLC)

NSCLC is the most common type of lung cancer and accounts for about 85%of lung cancers.4 NSCLC includes 3 main subtypes based on histology:


1. Adenocarcinoma: This type begins near the outside surface of the lung and grows slowly. It accounts for about 40% of lung cancers and occurs mainly in current or former smokers, but it is also the most common type of lung cancer seen in non-smokers, and more frequently seen in women and the young.4,5


2. Squamous cell carcinoma: This type generally begins in the lining of the airway in the larger breathing tubes, and often linked to a history of smoking. It accounts for about 25-30% of lung cancers and does not spread quickly.4,5


3. Large cell carcinoma: This type may occur in any part of the lung. It accounts for about 10-15% of lung cancers and tends to spread quickly.4,5
