It’s long been known that faulty BRCA genes greatly raise the risk for breast cancer. Now scientists say a more recently identified, less common gene can do the same.
Over the past decade, the phrases ‘BRCA 1’ and ‘BRCA 2’ went mainstream as genetic testing to assess breast cancer risk became common. But, now, doctors are telling patients whose tests were negative to get retested.
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.
According to experts, a man or woman with a particularly harmful gene mutation can have a 50 percent to 80 percent chance of getting breast cancer.
