New research shows that sleep or stay up late at night lights led to women suffering from breast cancer, one of the main factors.

Reported that a large number of studies have shown that working women who need night shifts, such as nurses, air crew, their risk of breast cancer up to 60%. Stay up all night 2-3 days a week the women are equally susceptible to breast cancer.
