Smith-Bindman, RebeccaMiglioretti, Diana LLurie, NicoleAbraham, LinnBarbash, Rachel BallardStrzelczyk, JodiDignan, MarkBarlow, William EBeasley, Cherry MKerlikowske, KarlaAfrican-American women are less likely to receive adequate mammographic screening than white women, which may explain the higher prevalence of advanced breast tumors among African-American women. Tumor characteristics may also contribute to differences in cancer outcomes because African-American women have higher-grade tumors than white women regardless of screening. These results suggest that adherence to recommended mammography screening intervals may reduce breast cancer mortality rates.DisparitiesCancerArticle
