    ### Response:
    Signs of non-small cell lung cancer include a cough that doesn't go away and shortness of breath. Sometimes lung cancer does not cause any signs or symptoms. It may be found during a chest x-ray done for another condition. Signs and symptoms may be caused by lung cancer or by other conditions.
