Night Work and Risk of Breast Cancer

Abstract

Our results suggest a modestly elevated risk of breast cancer after longer periods of rotating night work. Additional studies are warranted to rule out small sample size or uncontrolled sources for confounding as alternative explanations.

Short-term effects of night shift work on breast cancer risk: a cohort study of payroll data

“…Several epidemiological studies have observed an increased risk of breast cancer following long-term night shift work that we were not able to assess due to lack of work schedule data prior to 2007 (18,25,27,(49)(50)(51)(52). An unknown part of the cohort subjects employed during 2007-2012 were hired prior to 2007 where we have no information on working time.…”

Immunometabolism: Is it under the eye of the clock?

“…Various cancers have been linked to disrupted circadian cycles, such as lymphatic [47], prostate [48,49] and breast cancer [50]. In 2007 the International Agency for Research on Cancer (IARC) claimed that shift work with circadian disruption is a highly probable human carcinogen [51].…”

Arbeit zur falschen Zeit am falschen Platz? Eine Matching-Analyse zu gesundheitlichen Beanspruchungen bei Schicht- und Nachtarbeit

“…So können beispielsweise für das Brustkrebsrisiko von Flugbegleiterinnen eher kanzerogene ionisierende Strahlungen als die Lage der Arbeitszeit verantwortlich gemacht werden. Für Brustkrebsrisiken von Krankenschwestern liegen etwas besser kontrollierte Studien vor (Schernhammer et al 2006). Doch auch hier werden signifikante kausale Zusammenhänge bestritten (Kolstad et al 2010;Pesch et al 2010;Pronk et al 2010).…”
