Lung cancers are generally divided into two main categories: small cell lung cancer (SCLC) and nonâsmall cell lung cancer (NSCLC). NSCLC accounts for approximately 85% of all lung cancers. Histologically, NSCLC is divided further into adenocarcinoma, squamous cell carcinoma (SCC), and large cell carcinoma.
