what stage of cancer
Stages of non-small cell lung cancer: 1  Stage I non-small cell lung cancer: Cancer may be present in the underlying lung tissues, but the lymph nodes remain unaffected. 2  Stage II non-small cell lung cancer: The cancer may have spread to nearby lymph nodes or into the chest wall.
Small cell lung cancer stages are classified in one of two ways: 1  Limited stage: Cancer is in one lung, sometimes including nearby lymph nodes. 2  Extensive stage: Cancer has spread to the other lung, the fluid around the lung (the pleura) or to other organs in the body.
