CASE STUDY ON SQUAMOUS CELL CARCINOMA OF THE LUNG

Abstract

Lung cancer is one of the leading causes of cancer-related mortality worldwide, with smoking being the primary risk factor. Squamous cell carcinoma is a common histological subtype of non-small cell lung cancer, frequently associated with chronic tobacco use. This case study reports a 70-year-old male patient with a long history of smoking who presented with progressive respiratory symptoms, hemoptysis, chest pain, weight loss, and generalized weakness. Diagnostic investigations, including imaging, bronchoscopy, biopsy, and tumor marker analysis, confirmed grade 3A squamous cell carcinoma of the right middle lobe of the lung. The patient was managed with concurrent chemotherapy and radiotherapy using cisplatin and paclitaxel, along with supportive and symptomatic treatment. This report highlights the clinical presentation, diagnostic approach, treatment strategy, and the importance of early detection and multidisciplinary management in lung cancer.
