Can breast cancer be seen on ultrasound? A breast ultrasound is most often done to find out if a problem found by a mammogram or physical exam of the breast may be a cyst filled with fluid or a solid tumor. Breast ultrasound is not usually done to screen for breast cancer. This is because it may miss some early signs of cancer.
How does breast cancer appear on 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).
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%.
What do breast ultrasounds detect? A breast ultrasound produces detailed images of breast tissue. It can reveal if the lump is a fluid-filled cyst (usually not cancerous) or a solid mass that needs more testing.
