Scientists have identified 72  new genetic variants associated with the risk of breast cancer. In two recently published studies, researchers describe the new variants – including some that are associated with two biologically distinct types of breast cancer cases that don’t respond to hormonal therapy. These results come from a global project which involved over 500 scientists. Study authors say these findings are major contributions to the inherited biological basis of breast cancer, which might help lead to improved screening, earlier detection and better treatments for this disease.
