There are three categories of large cell lung cancer: squamous cell carcinoma (also called epidermoid carcinoma), adenocarcinoma, and large cell carcinoma. Large cell lung cancer is more common than small cell lung cancer, accounting for 80 percent of cases.
The causes of large cell lung cancer are believed to be exposure to asbestos, exposure to harmful substances like benzene, fiberglass, radon and others, and the combination of cigarette smoke and exposure to toxic substances.
Large cell lung cancer differs from small cell lung cancer in several ways. The cells can usually be treated with surgery even after they have spread, and they tend to grow and spread much more slowly. The cells also often do not spread outside the chest cavity until the disease is advanced.
The symptoms of large cell lung cancer include a persistent cough that worsens over time, continual chest pains, coughing up blood, shortness of breath, hoarseness, tightening in the chest, recurring pneumonia or bronchitis, inflammation of the face and neck, weight loss or loss of appetite, and extreme exhaustion.
