This animation explains how lung cancer staging is a system that doctors use to describe or classify the overall size and spread of the main tumor. Doctors need lung cancer staging information to help plan a patient’s treatment. Lung cancer is classified into several stages - the higher the stage the more advanced the spread of the disease and the more aggressive the treatment strategy. In Stage 0 the cancer is only in the top layers of the cells lining the lung’s air passages and this is the easiest stage to treat. In Stage IV the cancer has spread to the other lung, lymph nodes outside the lungs, and other parts of the body.
