Researchers say they have found a way to better calculate the risk a woman with cancer in one breast has of developing tumors in the other. Researchers in Houston found certain independent risk factors in women who had cancer in both breasts. 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.
