NSCLC irrespective of being adeno or squamous has propensity for metatstases 
Treatment options include for early stage Surgery ( Lobectomy or Pneumonectomy ) depending on stage and extent of disease, Intermediate stage lung cancer is treated with Neoadjuvant chemotherapy followed by Surgery or Radical chemo radiation depending on disease extent and Patient physiological condition There is an emerging role of Durvalumab in intermediate stage non resectable lesions
