Stage 3A lung cancer is considered locally advanced. This means the cancer has spread to the lymph nodes on the same side of the chest as the primary lung tumor, but not to distant areas in the body. The main bronchus, lung lining, chest wall lining, chest wall, diaphragm, or membrane around the heart may be involved. There be metastasis to the heart blood vessels, the trachea, the esophagus, the nerve governing the voice box, the chest bone or backbone, or the carina, which is the area where the trachea joins the bronchi.
