<strong>and</strong> <strong>Breast</strong> Cancer Risk Assessment<br />
RESULTS OF SUPPLEMENTAL ULTRASOUND SCREENING IN WOMEN WITH AND<br />
WITHOUT DENSE BREAST TISSUE<br />
Judy C Dean MD<br />
Recent awareness of the increased risk of breast cancer, <strong>and</strong> higher rate of interval cancer that escapes<br />
detecti<strong>on</strong> with mammography have led to recommendati<strong>on</strong>s for supplemental screening with ultrasound,<br />
yet little is known about the diagnostic yield of these examinati<strong>on</strong>s.<br />
Since November, 2005 I have performed almost 10,000 automated whole breast ultrasound studies with<br />
digital mammograms, primarily in women with either increased breast cancer risk or increased breast<br />
density. Stratificati<strong>on</strong> by breast density (as analyzed visually using the Bi-Rads classificati<strong>on</strong> system)<br />
shows significantly more cancers detected in women with increased breast density.<br />

The table above shows that half of all cancers detected were identified with automated breast ultrasound <strong>on</strong>ly, <strong>and</strong><br />
not imaged by mammography. Only <strong>on</strong>e of the additi<strong>on</strong>al cancers detected by ultrasound was DCIS, <strong>and</strong> all others<br />
were invasive cancers.<br />
