Lung cancer

Overview for patients

The lungs are a pair of cone-shaped breathing organs inside the chest. Two tubes called bronchi lead from the trachea (windpipe) to the lungs and each lung has sections called lobes. The lungs bring oxygen into the body when breathing in and send carbon dioxide out of the body when breathing out. 

The two main types of lung cancer are non-small cell lung cancer, which is much more common, and small cell lung cancer. The types are based on the way the cells look under a microscope.
