Non-Small Cell Lung Cancer
Non-small cell lung cancer is much more common than small cell lung cancer.
Types of non-small cell lung cancer
The three main kinds of non-small cell lung cancer are named for the type of cells in the tumor:
- Adenocarcinoma usually begins in the periphery of the lung and under the lining of the bronchi. It is the most common type of lung cancer in people who have never smoked.
- Squamous cell carcinoma is also called epidermoid carcinoma. It often begins in the bronchi near the middle of the lungs.
- Large cell carcinomas are a group of cancers with large, abnormal-looking cells. These tumors may begin anywhere in the lungs.
