Non-Small Cell Lung Carcinoma (NSCLC) is the most common type of lung cancer. It is a type of cancer that begins in the cells that line the airways of the lungs. NSCLC can be divided into three main types: adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Symptoms of NSCLC include a persistent cough, chest pain, shortness of breath, and coughing up blood. Treatment options for NSCLC include surgery, chemotherapy, radiation therapy, and targeted therapy.
