Outdoor Exposure to Artificial Light at Night and Breast Cancer Risk: A Case–Control Study Nested in the E3N-Generations Cohort
The weak positive associations observed in this study that persist after adjustment for environmental covariates, support the hypothesis that outdoor LAN may increase breast cancer risk. Our results, suggesting that urban greenness could mitigate the role of LAN exposure in breast cancer risk, should be investigated further. Future studies on cancer risk in relation to outdoor LAN should assess exposure to indoor sources, including electronic devices, and characterize the light spectrum, particularly the blue light. https://doi.org/10.1289/EHP15105.
