Sleep Patterns and Breast Cancer

SSS senior research analyst Aimee D’Aloisio is among the authors of an article in the International Journal of Cancer that describes an analysis of the association of sleep patterns with breast cancer risk. Using data from the Sister Study, researchers found that most sleep characteristics, including sleep duration, were not associated with an increased risk of breast cancer, although higher risk was observed for some markers of inadequate or poor quality sleep such as frequent difficulty sleeping, having a light or television on in the room while sleeping, or typically getting less sleep than needed to feel at one’s best. Coauthors included researchers from the National Institute of Environmental Health Sciences, National Cancer Institute, and University of North Carolina Chapel Hill.
