Researchers have discovered a genetic marker that, if present, indicates a significantly increased risk of developing breast cancer. Women with the variation in their DNA are 1.4 times more likely to develop breast cancer during their lifetimes than women whose genes do not contain the marker.

An article describing the work was published this week in the journal Proceedings of the National Academy of Sciences.

Ken Offit, one of the authors of the report, says that the newly identified genetic marker won't have immediate clinical implications on current screening guidelines for familial breast cancer, but that the findings may point to new molecular pathways that may be associated with breast cancer.
