Study: Gene Flaws Linked to Black Women’s Greater Breast Cancer Risk

Gene flaws that raise the risk of breast cancer are surprisingly common in black women with the disease, according to the first comprehensive testing in this racial group. The study found that one-fifth of these women have BRCA mutations, a problem usually associated with women of Eastern European Jewish descent but recently highlighted by the plight of Angelina Jolie.
The study may help explain why black women have higher rates of breast cancer at young ages — and a worse chance of survival.
Doctors say these patients should be offered genetic counseling and may want to consider more frequent screening and prevention options, which can range from hormone-blocking pills to breast removal, as Jolie chose to do.
“We were surprised at our results,” said the study leader, Dr. Jane Churpek, a cancer specialist at the University of Chicago. Too few black women have been included in genetic studies in the past and most have not looked for mutations to the degree this one did, “so we just don’t have a good sense” of how much risk there is, she said.
Churpek gave results of the study Monday at an American Society of Clinical Oncology conference in Chicago. The researchers include Mary-Claire King, the University of Washington scientist who discovered the first breast cancer predisposition gene, BRCA1.
