Stage I. Cancer at this stage has invaded the underlying lung tissue but hasn't spread to the lymph nodes.
Stage II. This stage cancer has spread to neighboring lymph nodes or invaded the chest wall.
Stage IIIA. At this stage, cancer has spread from the lung to lymph nodes in the center of the chest.
Stage IIIB. The cancer has spread locally to areas such as the heart, blood vessels, trachea and esophagus — all within the chest — or to lymph nodes in the area of the collarbone or to the tissue that surrounds the lungs within the rib cage (pleura).
Stage IV. The cancer has spread to other parts of the body, such as the liver, bones or brain.

Limited. Cancer is confined to one lung and to its neighboring lymph nodes.
