Description of the Evidence

Updated statistics with estimated new cases and deaths for 2018 (cited American Cancer Society as reference 1).

Revised text to state that breast cancer incidence rates increased slightly in black women by 0.3% per year between 2005 and 2014, resulting in the convergence of rates in blacks with those in whites.

Added text to state that family history and mutation location within the BRCA1 or BRCA2gene may contribute to the risk of cancer development among those with an inherited predisposition to breast cancer (cited Kuchenbaecker et al. as reference 28).

Added text about a nationwide prospective cohort study in Denmark that found that women who currently or recently used contemporary hormonal contraceptives had a higher risk of breast cancer than did women who had never used hormonal contraceptives; however, in absolute terms, the effect of oral contraceptives on breast cancer risk was very small (cited Mørch et al. as reference 128).
