Non-small cell lung cancer may be classified according to the WHO histological classification system into 3 main types: squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. Other less common subtypes, include: adenosquamous lung carcinoma, pulmonary sarcomatoid carcinoma, carcinoid tumors of lung, and carcinomas of the lung of salivary gland type.[1]
