Title Circadian clock disruptions and the risk of cancer Type Journal Article
Year 2012 Publication Annals of Medicine Abbreviated Journal Ann Med
Volume 44 Issue 8 Pages 847-853
Keywords Human Health; Cell Division; Chronobiology Disorders/*complications/genetics/*physiopathology; Circadian Clocks/*genetics; Humans; Neoplasms/*etiology; Work Schedule Tolerance/physiology
Abstract Disrupted circadian rhythms may lead to failures in the control of the cell division cycle and the subsequent malignant cell growth. In order to understand the pathogenesis of cancer more in detail, it is crucial to identify those mechanisms of action which contribute to the loss of control of the cell division cycle. This mini-review focuses on the recent findings concerning the links between the human circadian clock and cancer. Clinical implications concern not only feasible methods for the assessment of the circadian time of an individual or for the determination of the best time for administration of a drug of treatment, but also in the future genetic tests for screening and for planning treatment.

Title Light at night and breast cancer risk: results from a population-based case-control study in Connecticut, USA Type Journal Article
Year 2010 Publication Cancer Causes & Control : CCC Abbreviated Journal Cancer Causes Control
Volume 21 Issue 12 Pages 2281-2285
Keywords Adult; Aged; Aged, 80 and over; Breast Neoplasms/epidemiology/*etiology; Carcinoma/epidemiology/*etiology; Case-Control Studies; Circadian Rhythm/physiology; Connecticut/epidemiology; Female; Humans; *Light/adverse effects; Middle Aged; Population; Questionnaires; Risk Factors; United States/epidemiology; Work Schedule Tolerance/physiology; Oncogenesis
Abstract OBJECTIVE: To investigate the potential association between domestic exposure to light at night (LAN) and the risk of human breast cancer. METHODS: A case-control study of female breast cancer was conducted in Connecticut. A total of 363 incident breast cancer cases and 356 age frequency-matched controls were interviewed using a standardized, structured questionnaire to obtain information on sleeping patterns and bedroom light environment. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by unconditional multivariate logistic regression. RESULTS: A non-significantly increased risk of breast cancer was observed among postmenopausal women for those keeping lights on while sleeping (OR = 1.4, 95% CI 0.7, 2.7), those who reported mainly sleeping in the daytime (OR = 1.4, 95% CI 0.5, 4.3), and those not drawing the curtains/window shades while sleeping at night (OR = 1.2, 95% CI 0.8, 1.9). CONCLUSION: The results from this study suggest a potential increased risk of breast cancer associated with domestic exposure to LAN. Further studies with larger sample size are needed to confirm the results.
