STAGE III NON-SMALL CELL LUNG CANCER

Cancer has spread to structures near the lung; to the lymph nodes in the area that separates the two lungs(mediastinum); or to the lymph nodes on the other side of the chest or in the lower neck. Stage III is further divided into stage IIIA (usually can be resected which is sometimes treated with surgery) and stage IIIB (usually cannot be resected which is rarely treated with surgery).
