Balanced News: Breast cancer breakthrough: NZ-led research finds way to reduce risk without surgery

A global study led by the University of Otago has discovered a gene that, when modified, could reduce the risk of breast cancer. The research involved 26,000 women known to have the BRCA-1 and BRCA-2 mutations of the breast cancer genes, the largest study of its kind. The researchers also discovered that women who have the BRCA-1 gene with segments missing are at the highest risk of developing breast cancer.
