Shift Work Does Not Increase Breast Cancer Risk

From the WebMD Archives

Oct. 6, 2016 -- Working night shifts does not increase women's risk of breast cancer, a new study says.

Researchers in the U.K. examined data from 1.4 million women and found no association between night shift work and breast cancer, BBC News reported.

The study appears in the Journal of the National Cancer Institute.

In 2007, a World Health Organization committee said studies in people and animals suggested that shift work "probably" had a link to breast cancer, BBC News reported.
