    Am J Epidemiol 165:1187-98. 2007
    ..These results emphasize that timing of exogenous hormone use is important. Women who used these hormones before menopause had elevated risks, but the harmful effects began to decline with age after menopause...

    Sharon K Sagiv
    Department of Epidemiology, School of Public Health, University of North Carolina, Chapel Hill, NC, USA
    Environ Res 109:287-91. 2009
    ..Results from this large population-based study do not provide strong support for an association between detectable PAH-DNA adducts and survival among women with breast cancer, except perhaps among those receiving radiation treatment...

    Breast Cancer Res Treat 108:93-9. 2008
    ..p53 participates in cell cycle control, programmed cell death/apoptosis, and DNA repair, all pathways involved in carcinogenesis. TP53 variants may influence p53 function...
