What does breast cancer look like with an ultrasound? The transducer is moved over the skin of the breast to create a picture that can be seen on a computer screen. Cancers are usually seen as masses that are slightly darker (“hypoechoic”) relative to the lighter gray fat or white (fibrous) breast tissue (Figs. 10, 11).
Can you tell if a breast lump is cancerous from an ultrasound? If an abnormality is seen on mammography or felt by physical exam, ultrasound is the best way to find out if the abnormality is solid (such as a benign fibroadenoma or cancer) or fluid-filled (such as a benign cyst). It cannot determine whether a solid lump is cancerous, nor can it detect calcifications.
Is breast cancer black or white on ultrasound? “Cancers are white on mammography, and so is dense breast tissue, whereas on ABUS, cancers are black on a white background,” says Dr. Jerrold Weiss, who discovered Zoll’s cancer with his new GE Healthcare Invenia 2.0 ABUS. “Only ultrasound can see through the dense tissue.”
How accurate is an ultrasound in finding breast cancer? It is known that ultrasound is effective for the detection of small, invasive, node-negative cancers in dense breast tissue, where the sensitivity of mammography drops from 85% to 47.8% to 64.4%.
