Women at high breast cancer risk can now take up a genetic testing to know whether they are BRCA2 positive. Hopefully, someday scientists will work out a procedure to correct the abnormalities in genes causing cancer. But for now, there are a number of preventive measures to choose from.</p><p>For a woman, testing BRCA2 positive means she is at much higher-than-average risk of developing breast cancer in her lifetime. It means that a woman is 3 to 7 time more likely to develop breast cancer than any other woman without any gene abnormalities. It also means that she is at 16% to 60% more risk of developing ovarian cancer in her lifetime. Being BRCA2 positive also means that there are 50% chances of passing the abnormalities to the children. <br></p>costaricacondosMon, 14 Dec 2009 03:03:11 -0000http://www.thinkgene.com/breast-cancer-risk-amplified-by-additional-genes-in-combo-with-brca-mutation/#comment-16486100<p>Changes in certain genes increase the risk of breast cancer. These genes include BRCA1, BRCA2, and others. Tests can sometimes show the presence of specific gene changes in families with many women who have had breast cancer. Health care providers may suggest ways to try to reduce the risk of breast cancer, or to improve the detection of this disease in women who have these changes in their genes.</p>brca1 mutationSat, 12 Sep 2009 01:41:06 -0000
