They say having cancer cells with certain invasive characteristics and having cancer in more than one quadrant of the breast increases the risk. They also found a greater risk for women who are initially diagnosed with breast cancer at age 50 or older, or who have additional moderate to high-risk cells in their affected breast.

The study which will be published in the March issue of Cancer.
