Title: Light at night as a potential cause of breast cancer
The rate of research on human health effects of exposure to light at night has increased rapidly in the past decade, especially with regard to cancer. In 2007, the International Agency for Research on Cancer (IARC) classified shift work involving circadian disruption as ‘probably carcinogenic to humans’, which has significant implications given that approximately 25% of the working population in Canada are engaged in shift work. This seminar will explore the current state of evidence on the relationship between shift work and breast cancer, as well as discuss research challenges and future directions.
Presenter:  Michael Leung
Michael Leung is a junior epidemiologist and data analyst at the Hospital for Sick Children. He has a Masters in Epidemiology from Queen’s University, where his thesis focused on how different patterns of shift work influence daily melatonin patterns. His current research interest lies in further understanding the chemical origins of chronic disease.
