- Stage I. The cancer is found only in the lung and is surrounded by normal tissue. * Stage II The cancer has spread to nearby lymph nodes.
- Stage III. The cancer has spread to the chest wall or diaphragm near the lung, or the cancer has spread to lymph nodes in the area that separates the two lungs (mediastinum) lymph nodes or across the chest, or neck.
