Mammography screening and differences in stage of disease by race/ethnicity

Am J Public Health. 2002 Jul;92(7):1144-50. doi: 10.2105/ajph.92.7.1144.


Objectives: We examined the effect of routine screening on breast cancer staging by race/ethnicity.

Methods: We used a 1990 to 1998 mammography database (N = 5182) of metropolitan Denver, Colo, women to examine each racial/ethnic cohort's incident cancer cases (n = 1902) and tumor stage distribution given similar patterns of routine screening use.

Results: Regardless of race/ethnicity, women participating in routine screenings had earlier-stage disease by 5 to 13 percentage points. After control for possible confounding factors, White women were more likely to have early-stage disease compared with Black and Hispanic women.

Conclusions: Lack of screening coverage in certain racial/ethnic populations has often been cited as a reason for tumor stage differences at detection. In this study, correcting for screening did not completely reduce stage differentials among Black and Hispanic women.
