NCI--Researchers have identified genetic variations in a region of DNA that may be associated with risk for breast cancer. Women with the variation have a 1.4 times greater risk of developing breast cancer compared to those without this variation. The study is one of several genome-wide association studies looking for breast cancer genes to be published this year by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and their colleagues. These findings appeared online in the Proceedings of the National Academy of Sciences on March 3, 2008.
