The number of women affected by breast cancer every year is staggering: almost 180,000 new cases and upwards of 40,000 deaths. Researchers are focused on finding novel ways to detect a malignancy before it spreads-to the lymph nodes and beyond. Dr. Wendie Berg, a breast imaging radiologist associated with the Johns Hopkins University School of Medicine, talks with host Dr. Lisa Mazzullo about her latest work: studying the use of ultrasound, in conjunction with mammography, to detect breast cancer in high-risk women.
