According to a new study, published in the journal Breast Cancer Research, women who live in places with the air thick with pollutants may have more chances of getting breast cancer.
For the study, Dr. Lusine Yaghjyan, an author of the study, and her team analyzed the records of about 280,000 women aged 40 and older who had mammograms. The scientists classified their breast as dense or fatty according to standard definitions.
Dr. Yaghjyan, an assistant professor of epidemiology at the University of Florida, says: “It appears that women who have dense breasts have a 20 percent greater likelihood of having been exposed to smog. However, the findings also raise a number of questions about why and how air pollution seems to increase breast density.”
