Explanation:
Detailed explanation-1: -Introduction: Histologically lung cancer is classified into four major types: adenocarcinoma (Ad), squamous cell carcinoma (SqCC), large cell carcinoma (LCC), and small cell lung cancer (SCLC).
Detailed explanation-2: -Squamous cell carcinoma: Squamous cell carcinomas start in squamous cells, which are flat cells that line the inside of the airways in the lungs. They are often linked to a history of smoking and tend to be found in the central part of the lungs, near a main airway (bronchus).
Detailed explanation-3: -Adenocarcinoma is the most common type of lung cancer, accounting for more than 40% of lung cancers, 60% of the NSCC, and more than 70% of surgically resected cases.
