Understanding Breast Density
A new federal rule requires mammography centers to inform women about their breast density, underscoring its importance in breast cancer screening. Dense breasts, which are normal and common, can make it harder to detect cancer on mammograms.
Breast density is classified into four categories, with "heterogeneously dense" and "extremely dense" indicating denser breasts. This classification can vary by the interpreting radiologist, highlighting the subjective nature of density assessment.
Implications and Actions
Women with dense breasts face a slightly higher risk of developing breast cancer and may benefit from additional screening methods like ultrasound or MRI, despite current insufficient evidence for broad recommendations. Regular mammograms remain essential.
Insurance coverage for additional screenings varies, with a proposed bill in aimed at requiring insurers to cover these costs for women with dense breasts. The out-of-pocket expense for additional screening can be a significant barrier.
