Doppler Ultrasound Helps Identify Breast Cancer Without Biopsy

Doppler Ultrasound Helps Identify Breast Cancer Without Biopsy

An article just published in the medical journal Radiology finds that 3-D Doppler ultrasound can help distinguish between malignant and benign breast lesions. In a group of women with suspicious breast lesions, 3-D power Doppler assessment of lesion vascularity had a 100% sensitivity and 86% specificity.  That means that women who have benign lesions (not cancer) could avoid having to get a biopsy to determine whether the lesion is cancer.

The basis for the distinction between malignant and benign is that 3-D power Doppler ultrasound can detect the higher flow velocities in the malignant tumor-feeding vessels have higher flow velocities when seen on Doppler and benign breast masses have slower flow velocities.
