160P - Distribution of mammographic density and its relationship to age in men
Abstract
Background
While the distribution of mammographic density and its inverse relationship to age have been described in women, such characterization is lacking in men.
Methods
A total of 791 diagnostic mammograms with digital breast tomosynthesis performed in men at a single academic institution were reviewed retrospectively to describe breast density in ACR BI-RADS classes. The relationship between breast density and age was examined using one-way analysis of variance with ranks.
Results
Almost entirely fatty breasts were the most common in men (61.9%), followed by the categories of scattered fibroglandular density (31.5%), heterogeneously dense (5.7%), and extremely dense (0.9%). While age had a statistically significant effect on breast density (P=0.041), the effect was attributed to a modest increase in breast density at extremes of age (<40 and ≥80 years). No statistically significant difference in breast density was seen from the age of 40s to 70s (P=0.224).
Conclusions
Mammographic density in men is heavily skewed towards low-density categories. Unlike in women, no general trend between age and breast density exists in men. The determinants and implications of high breast density in men remain to be investigated.
