Although defects in the “breast cancer gene,” BRCA1, have been known for years to increase the risk for breast cancer, exactly how it can lead to tumor growth has remained a mystery. In the October 15, 2007, issue of the journal Cancer Research, scientists from the University of Chicago and Kyoto University, Japan, suggest that a mechanism that normally repairs damaged DNA may function abnormally in BRCA1 carriers leading to one type of poor-prognosis breast cancer.
