Night / Shift Work May Increase Breast Cancer Risk.
Women who work non-traditional hours over the course of a career may have a slightly greater risk for a breast cancer diagnosis than those who work “9-5.” Researchers combed through 25 studies regarding “breast cancer risk” and “night work” or “shift work” published during the last twenty years and found long-term night/shift work may be associated with a 9% greater risk for breast cancer.
