The point of our study was to compare levels of breast density for black and white women using quantitative breast density measures from a computer algorithm. Racial variances in BMI might have contributed to the lower breast density observed among black women in previous studies, according to study background. McCarthy and colleagues evaluated data from 2, black and white women mean age, 57 years with no previous history of breast cancer. All the women had their BMI recorded at the time of mammography screening.
Black women demonstrate denser breast tissue than white women
Racial Differences in Quantitative Measures of Area and Volumetric Breast Density
Background: Increased breast density is a strong risk factor for breast cancer and also decreases the sensitivity of mammographic screening. The purpose of our study was to compare breast density for black and white women using quantitative measures. Methods: Breast density was assessed among black and white women screened using digital mammography. Quantitative measures for dense area, area percent density PD , dense volume, and volume percent density were estimated using validated, automated software. Breast density was categorized as dense or nondense based on BI-RADS categories or based on values above and below the median for quantitative measures.
A study using a new tool to measure mammographic density found that black women have denser breast tissue than white women. The findings add to the research on breast density, cancer disparities, and risk-based screening. Breast density refers to the amount of fibroglandular tissue in the breast when observed on a mammogram. Dense breast tissue shows up white on a mammogram, as do cancer cells, making it difficult for the radiologist to spot a tumor.
