Most cancers in the lung are carcinomas-cancers of epithelial cells. The top pair of images shows the normal epithelium of the bronchi. This photomicrograph is greatly enlarged.

The subglottis connects to the trachea, which takes air to the lungs. Cancer of the larynx, can also be called laryngeal cancer, can develop in any part of the larynx, but most begins in the glottis. The inner walls of the larynx are lined with cells called squamous cells. Almost all laryngeal cancers begin in these cells. If cancer of the larynx spreads, the cancer cells often spread to nearby lymph nodes in the neck. The cancer cells can also spread to the back of the tongue, other parts of the throat and neck, the lungs, and other parts of the body.
