Purpose
To evaluate the distribution of breast density among Jordanian women and its relationship with age and relate it to other countries.
In Jordan, a Middle Eastern Asian country, breast cancer is the most frequent cancer and constitutes 36.4% of all reported female cancers in 2018 (1). The distribution of the cases by age group shows that most of the cases 30% were in the age group 40-49 years and 24.9% in the age group 50-59 (2). According to Jordan National Cancer Registry report in 2012,...
Methods and materials
We conducted a retrospective review of all mammograms performed from January 2016 to August 2018 at King Abdullah II University Hospital. Each case consisted of a standard two-view mammograms of both breasts. Mammograms were obtained using digital mammography unit.
Mammographic breast density was defined according to the American College of Radiology Breast Imaging Reporting and Data System (ACR-BIRADS 5th version) as follows: ACR-BIRADS (a) the breasts are almost entirely fatty; (b) there are scattered areas of fibroglandular density; (c) the breasts are heterogeneously dense, (d)...
Results
As shown in Figure 1, there was a total of 58 (8.8%) women with ACR-BIRADS (a) (entirely fatty) on mammography, 144 (21.9%) with ACR-BIRADS (b) (scattered areas of fibroglandular density), 375 (56.9%) with ACR-BIRADS (c) (heterogeneously dense), and 82(12.4%) with ACR-BIRADS (d) (extremely dense). The distribution of women in each mammographic density category is described in Table 1.
The study population was categorised into five-year age groups as shown in Figure 2. There were 82 women (12.4%) younger than 40 years of age, 249 (37.8%)...
Conclusion
The findings in this study confirms the inverse relationship women’s age and mammographic breast density. The results suggest that a significant proportion of younger women have ACR-BIRADS c and d of mammographic density which could potentially benefit from the use of additional imaging methods such as ultrasound, MRI or DBT combined with mammography. For young age women with low mammographic density, mammography alone could be used as sufficient sensitive modality for early breast cancer detection. A meaningful proportion of women had dense breasts at their...
