Lung cancer is cancer that usually starts in the lining of the bronchi (the main airways of the lungs), or other areas of the lungs, including the bronchioles, or alveoli.
Nearly all lung cancers are carcinomas, a cancer that begins in the lining or covering tissues of an organ.
Lung cancers are generally divided into two types:
- 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:
- Squamous cell carcinoma (also called epidermoid carcinoma)
- Large cell carcinomas
- Small cell lung cancer: There are two stages of small cell lung cancer:
- Limited: cancer is generally found in only one lung.
- Extensive: cancer has spread beyond the primary tumor in the lung into other parts of the body.
