  1. Data presented as average ± standard deviation. DMIN was calculated using DMIN = T1(MIN) − T0(MIN) + 1. DMIN, total time over which each MIN lesion was detected; MIN, mammary intraepithelial neoplasia; T0(IC), average age when invasive cancer is first detected; T0(MIN), time when MIN is first detected; T1(MIN), average age when MIN is last detected.
