Exposition à la lumière la nuit et cancers du sein et de la prostate : étude en population générale à Madrid et Barcelone Volume 17, issue 5, September-October 2018



This news is based on the following article: Garcia-Saenz A, Sánchez de Miguel A, Espinosa A, et al. Evaluating the association between artificial light-at-night exposure and breast and prostate cancer risk in Spain (MCC-Spain Study). Environ Health Perspect 2018 ; 126 : 047011. doi : 10.1289/EHP1837


This study* conducted in the two largest cities in Spain helps to fill in the gaps in our knowledge about the association between environmental exposure to artificial light at night and hormone-dependent cancers. Its results indicate an effect specific to blue light. They must nonetheless be interpreted with prudence, since the exposure assessment method requires further improvement.
