Does outdoor light contribute to ovarian cancer mortality? Insights from a case-control study
Unfavorable light environments, including artificial light at night (ALAN) and ultraviolet B (UVB) radiation, may be linked to ovarian cancer, but this association remains uncertain. A multicenter case-control study in Northeastern China was performed. Using propensity score matching, we matched individuals who died from other cancers with controls in a 1:1 ratio. Exposure levels were determined by monthly average outdoor ALAN exposure (0.5 ×0.5 km), UVB radiation (0.25°×0.25°), and PM
