ATM and breast cancer: For ATM, the PV rates of 0.9% in women affected with breast cancer and 0.5% in unaffected women were similar to those observed in the Women’s Health Initiative (0.73% in women diagnosed with breast cancer after menopause, 0.30% in unaffected women) and the CARRIERS study (0.78% in affected women and 0.41% in unaffected women) [18, 30].
