Breast cancer screening using tomosynthesis and digital mammography in dense and nondense breasts
A partir de données portant sur 452 320 procédures d'imagerie du sein aux Etats-Unis, cette étude évalue, en fonction de la densité mammaire, les taux de détection et de rappel associés à l'ajout d'un examen par tomosynthèse à une mammographie numérique
Breast density is associated with reduced mammographic sensitivity and specificity. Additionally, increased tumor size and worsened prognosis are associated with increased breast density. Dense breast tissue may also represent an independent risk factor for breast cancer. Currently, 24 states have laws mandating that women be notified of the implications of breast density, thereby encouraging discussions between patients and physicians regarding the need for supplemental screening. However, which, if any, additional modalities should be recommended for women with dense breasts is not known.
