Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for approximately 85% of all lung cancer cases. It is characterized by the presence of large, abnormal cells that form tumors in the lung tissues. NSCLC is typically divided into several subtypes, including adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Research in the field of NSCLC focuses on understanding the underlying genetic and molecular mechanisms that drive the development and progression of the disease. This includes studying the role of specific genetic mutations, such as those in the EGFR or ALK genes, in driving tumor growth and resistance to treatment. Researchers also investigate ways to improve early detection methods, develop targeted therapies that specifically target cancer cells, and improve overall patient outcomes through personalized treatment approaches. Overall, research in NSCLC aims to improve the understanding of the disease, identify new treatment options, and ultimately improve survival rates for patients with this type of cancer.
