Researchers have uncovered a potential preventative treatment for breast cancer, other than surgery, in women with BRCA1 and BRCA2 gene mutations. If it proves successful in mouse models, human clinical trials of this early intervention method will be carried out. It follows work by the University of Cambridge, European Bioinformatics Institute (EMBL-EBI) and Wellcome Sanger Institute to create the world’s largest catalogue of human breast cells. This revealed early cell changes in healthy carriers of BRCA1 and BRCA2 gene mutations. While everyone carries these genes, mutations in them – which…
