==Overview==
Primary lung cancers may be classified into [[small cell lung cancer]] (~15%) and [[non small cell lung cancer]] (~85%).  [[Non small cell lung cancer]] are a heterogenous group of lung cancers that are often grouped together because they share similar clinical features (e.g. [[prognosis]] and management). The 2004 WHO histological classification of [[tumors]] of the [[lung]] categorized [[lung]] [[tumors]] into [[malignant]] [[epithelial]] [[tumors]], [[benign]] [[epithelial]] [[tumors]], [[Lymphoproliferative disorders|lymphoproliferative tumors]], miscellaneous [[tumors]], and [[metastatic]] [[tumors]].

Overview

Primary lung cancers may be classified into small cell lung cancer (~15%) and non small cell lung cancer (~85%). Non small cell lung cancer are a heterogeneous group of lung cancers that are often grouped together because they share similar clinical features (e.g. prognosis and management). The 2015 WHO histological classification of tumors of the lung categorized lung tumors into malignant epithelial tumors, benign epithelial tumors, lymphoproliferative tumors, miscellaneous tumors, and metastatic tumors.

Classification

Primary lung cancers may be classified into two main categories:[1]
