In UK, about 3 percent of breast cancer cases inherited
Apr 27, 2011
In the UK, about 3 percent of all breast cancer cases are passed through inherited genes, according to a new report from the Daily Mail.
Scientists have long been aware of the breast cancer mutation genes BRCA1 and BRCA2, and genetic testing is available for those who wish to see if they are susceptible to breast cancer.
"Women who are carriers of the mutated gene BRCA1 or BRCA2 are more likely to inherit the condition. If a blood relative — male or female — had breast cancer at an early age, you are more at risk," said Jackie Harris of Breast Cancer Care.
The report links excessive drinking and smoking to increased chances of breast cancer. In the U.S., the incidence of breast cancer is about one in eight women, according to the American Cancer Society.
Many women who develop breast cancer do not have a family history of the disease and researchers are continuing to look for links between potential risk factors and the occurrence of breast cancer.
