It will be better for women not to take up night shifts, as a new research has revealed that it can increase breast cancer risk among them. The study was carried out by a group of researchers from the Institut National de la Sante et de la Recherche Medicale (Inserm).

Lead researcher Pascal Guenel of Inserm was of the view that they have gone through previous studies and after evaluating all the previous data, they have reached at a conclusion that night shift jobs are not healthy for women.

"Our work has corroborated the results of previous studies and poses the problem of taking night work into consideration in public health management", said Pascal.

Study researchers not only assessed previous studies, but they also conducted a research in which they assessed health implication of night shifts on 3,000 women, who were working in France from 2005 to 2008.

In four -year-long -study, it was revealed that women, who had worked in night shifts, were at increased risk of developing breast cancer, which is believed to be the biggest reason of female mortality.

Pascal said that it seems to be one of a kind study, which has proved that night shifts and occurrence of breast cancer is linked.
