Non-Small Cell Lung Cancer (NSCLC) is the most common type of lung cancer, accounting for approximately 85% of all lung cancer cases. Unlike small cell lung cancer (SCLC), NSCLC tends to grow and spread more slowly. NSCLC is categorized into three primary types: adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Each type has unique histopathological characteristics.
