Disease Analysis: Non-Small Cell Lung Cancer (NSCLC)

Lung cancer is generally categorized as either small cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC). Of these, NSCLC is the most common type of lung cancer, accounting for roughly 85% of all cases. NSCLC can be further divided into non-squamous and squamous NSCLC histologies. Squamous NSCLC refers to patients with squamous cell carcinoma, whereas non-squamous NSCLC includes patients with adenocarcinoma, large cell carcinoma, and other less common subtypes. Incidence of adenocarcinoma and squamous cell carcinoma varies greatly by both geographic region and gender. In general, adenocarcinoma comprises approximately 30–50% of all lung cancer cases, while squamous cell carcinoma accounts for roughly 25–35%.
