The role of race and residence in determining stage at diagnosis of breast cancer.

Breast cancer kills more than 46,000 women each year. Previous research has found that minorities and those who reside in geographically remote settings are particularly vulnerable. However, virtually no research has been done on the potential "double jeopardy" faced by rural minority women. This research examines (1) the extent to which racial and residential differences contribute to differences in stage at diagnosis; (2) the existence of an interaction between race and residence, which may place black rural women at greater risk; and (3) the influence of both individual and structural characteristics on racial and residential differences. The findings indicate that rural black women are diagnosed with breast cancer much later than are black urban women or whites of either residence. A number of individual and structural variables were influential in predicting stage at diagnosis, yet none of these accounted entirely for racial differences.
