Dr. Jafi Lipson, from Stanford University Medical Center, and colleagues gave a nine-question survey to 132 women at a county hospital, prior to the women's mammogram appointments. The surveys were available in English, Spanish, and Vietnamese.
Participants were asked if they were aware of their breast density, they were informed about the decreased sensitivity of mammography in dense breast tissue, and they were asked whether they were willing to pay for additional testing if they had dense tissue. A similar survey was conducted at an academic hospital outpatient radiology clinic.
At the county hospital, 5% of women knew their breast density status, compared with 24% of women at the outpatient clinic. Seventy-nine percent of women at the county hospital wanted to know their breast density and were interested in additional screening tests, despite high false-positive rates. Seventy-three percent were interested in whole-breast ultrasound, but only 28% were will to pay out of pocket for the test, compared with 73% of women at the outpatient clinic.
The discrepancy could lead to inequity in healthcare if supplemental tests for women with dense breast tissue are not covered by insurance, Lipson's group concluded.
