Radon exposure: a major cause of lung cancer

摘要: Introduction: Lung cancer is the most important cause of mortality. It a multifactorial disease with multiple risk factors, including residential radon exposure. Areas covered: The aim this paper was to review epidemiology exposure and its impact on lung risk. While tobacco main factor cancer, first in never-smokers second ever-smokers. Moreover, synergistic effect between consumption should be considered. However, biological mechanism by which decay products induce not entirely known. Expert opinion: Residential usually neglected clinicians. In fact, no score (predicting incidence or mortality) includes as variable. Further studies are needed find out molecular pathways that whether radioactive gas also involved development other diseases than cancer. There clear need increase awareness among administrations, health professionals general population order take necessary measures reduce harmful exposure, particularly radon-prone areas.
