European ancestry increases breast cancer risk among Latinas

Latina women have a lower risk of breast cancer than European or African-American women generally, but those with higher European ancestry could be at increased risk, according to data published in the December 1 issue of Cancer Research, a journal of the American Association for Cancer Research. "We need to study the possible factors that are placing Latina women of high European ancestry at greater risk," said Laura Fejerman, Ph.D., a post-doctoral research fellow at the University of California San Francisco. "The increased risk could be due to environmental factors, genetic factors or the interplay of the two." Latinas are what geneticists refer to as an "admixed" population with most of their genetic ancestry from European or indigenous Americans. Fejerman said the term "indigenous Americans" usually refers to the groups that lived on the American continent prior to the arrival of the European colonizers. READ FULL STORY
