Abstract
Background: With recent advances in breast cancer risk reduction practices, it is increasingly important to assess both the breadth of and disparities in use across different racial/ethnic groups. Methods: We conducted telephone interviews with 1,700 women ages 40 to 74, from four racial/ethnic groups, without prior history of breast cancer, who received mammograms at one of five mammography facilities in San Francisco. Main outcomes measured included recognition of tamoxifen, raloxifene, genetic testing, and prophylactic surgery. Global indicators (recognition of any therapy, discussion of breast cancer risk) were developed from original outcome measures and analyzed using logistic regression. Results: Multivariate analyses indicate that race/ethnicity and interview language affected recognition of therapies and discussion of risk. White women were more likely than all other women to recognize any therapy and more likely than Asian-Americans to discuss risk. Women at high risk, who had a prior abnormal mammogram, who perceived themselves to be at high risk, or who were exposed to breast health information were more likely to discuss risk. Conclusions: Women are aware of preventive therapies, although discussion and use is limited. Interventions to increase use of therapies should focus on those at high risk.
