A new genetic test developed by King’s College London researchers offers promising results in predicting who may develop invasive breast cancer after detection of abnormal cells. The study involved more than 2,000 women from the UK who had their DNA tested for 313 genetic changes to create a genetic risk score. A genetic risk score estimates an individual’s inherited susceptibility to developing a disease based on the combined impact of multiple genetic variants. However, with the accuracy provided by the genetic risk score, treatment can be customized to individual risk profiles, sparing many from unnecessary procedures. Simon Vincent, chief scientific officer at Breast Cancer Now, also underscored the potential of this research to enhance patient care.
