Abstract
No association was found between residential outdoor light at night exposure and breast cancer risk based on data from 844 cases and 905 controls.
- Cumulative average outdoor light at night exposure was measured using satellite data from 5-20 years prior to study entry.
- Logistic regression was employed to analyze the relationship between outdoor light at night and breast cancer risk, factoring in menopausal status and night shift work.
- The odds ratio for the highest versus lowest tertile of outdoor light at night exposure was 0.95, suggesting no increased risk.
- Findings remained consistent when adjusting for various factors, including years of residential data and residential mobility.
- Results align with previous research indicating minimal or no impact of outdoor light at night on breast cancer risk.
