About the study: 

British Columbians are employed in jobs that involve night shift work. Night shift work has been linked to increased risks of cancer. To protect the health of night shift workers, we are conducing a research study aimed at understanding the biological mechanisms by which night shift work causes cancer. One possible mechanism involves the disruption of gut microbes, whose normal functioning is critical to maintaining good health.
