Non-Small Cell Lung Cancer
Overview
Accurate staging of non-small cell lung (NSCLC) cancer is essential before definitive therapy can begin. Staging is performed according to the tumor, node, metastasis (TNM) staging system. Select the following general stage of cancer in order to learn more about treatment.

Stage I: Cancer is located in only one lung and has not spread to the adjacent lymph nodes or outside the chest.

Stage II: Cancer is located in one lung and may involve lymph nodes on the same side of the chest but does not include lymph nodes in the space between the lungs (the mediastinum) or outside the chest.

Stage IIIA: Cancer is a single tumor or mass that is not invading any adjacent organs and involves one or more lymph nodes away from the tumor, but not outside the chest.

Stage IIIB: Cancer has spread to more than one area in the chest, but not outside the chest.

Stage IV: Cancer has spread, or metastasized, to different sites in the body, which may include the liver, brain or other organs.

Recurrent/Relapsed: Cancer has progressed or returned (recurred/relapsed) following an initial treatment with surgery, radiation therapy and/or chemotherapy.
