(NEWSCHANNEL 3) - A new report is linking breast cancer and working at night.

New research finds women who work nights for 30 years or more have double the risk of getting breast cancer.

Previous studies done on nurses had similar results but this study out of Canada finds the risk applies to all night shift work and not just nursing.

Researchers think disruptions to the sleep hormone melatonin could be linked to the increased cancer risk.
