Breast cancer discovery shocks scientists

Breast cancer discovery shocks scientists – A new study from Harvard University has discovered that there’s a increased chance of breast cancer in women who reside in areas with a lot of artificial light outside during the night.

Breast cancer discovery shocks scientistsResearchers utilized the Nurses’ Health Study to come to their conclusions, following nurses in the NHS for breast cancer occurrence between 1989 and 2013.

They diagnosed 3,549 new cases of breast cancer by 2013, which is a typical percentage. The study found that there seemed to be a direct relationship between nighttime light level and the risk for developing breast cancer, and it appears that the higher that light level is, the greater the risk.

“A sizable long-term research found that breast cancer risk could be higher for girls who reside in regions having elevated levels of outdoor lighting during the nighttimetime,” the Harvard statement reads. “The connection between outside light during the night and breast cancer has been found only among women who were premenopausal and were present or past smokers, also was stronger among people who worked night shifts.”

“In our modern day, artificial lighting is almost ubiquitous.

Our results imply that this widespread exposure to outside lights during night hours may represent a new risk factor for breast cancer,” said lead author Peter James, assistant professor in Harvard Medical School’s Department of Population Medicine at Harvard Pilgrim Health Care Institute, that did the job as a research fellow at the Departments of Epidemiology and Environmental Health at Harvard Chan School.
