This could include cancer that is found in part of one lung and may have spread to the lymph nodes on the same side as the tumour. It may also include the lymph nodes in the centre of the chest (mediastinum). Limited stage small cell lung cancer can be treated with radiation to a single area of the body.
Extensive stage small cell lung cancer has spread widely in the lung with the tumour, to the other lung, to the lymph nodes on the other side of the chest from the tumour, or to other parts of the body.
