Lung Squamous Cell Carcinoma

Lung squamous cell carcinoma, also known as epidermoid carcinoma, is a type of non-small-cell lung cancer that arises from the thin, flat cells lining the airways, accounting for approximately 30% of all lung cancers. It typically develops in the central air passages of the lungs and is one of the major subtypes of non-small-cell lung cancer, alongside adenocarcinoma and large cell carcinoma. While early stages may be asymptomatic, common symptoms include coughing, chest pain, weight loss, and fatigue; if the cancer spreads beyond the lungs, it may cause difficulty swallowing or shortness of breath. Non-small-cell lung cancers represent about 85% of all lung cancer cases, highlighting the significance of squamous cell carcinoma within this group.
