breast ultrasoundMammography is the only breast cancer screening tool that has been proven to reduce deaths through early detection. However, other imaging modalities can be valuable when a supplement or alternative to mammography is needed. Women who are unable to undergo mammography or whose mammography images provide insufficient information are often referred for breast ultrasound.

 

When is ultrasound used for breast imaging?

Investigating Identified Areas of Interest

The most common use of breast ultrasound is to gain additional information about areas of concern identified on a mammogram or through a physical exam. Ultrasound is a useful tool for determining whether an abnormal area is solid, fluid filled, or a combination of the two, which can provide insight into whether it’s more likely to be cancer or a benign feature.

 

Screening for Women Who Cannot Undergo Mammography

For some women, exposure to X-rays is contraindicated. The most common reason for this is pregnancy. In these cases, ultrasound is sometimes used for breast cancer screening. Ultrasound, however, is not the first choice for breast cancer screening because it can miss early signs such as microcalcifications, and obesity or very large breasts can make ultrasound less effective.

 

Supplemental Screening for Women with Dense Breast Tissue

Dense breast tissue can make irregularities difficult to spot on a mammogram. Particularly if you are at a higher than average risk of breast cancer, your doctor may recommend additional screening with ultrasound to better identify potentially problematic areas. Be aware, however, that breast ultrasound is associated with a high level of false positive results—identified abnormalities that turn out to be benign.

 

Supplemental Screening for Women at High Risk Who Can’t Undergo MRI

Women who are at high risk of developing breast cancer are most often referred for additional screening using MRI to increase the chances of catching developing cancer early. However, when MRI is contraindicated, ultrasound provides a valuable alternative for providing additional information.

 

Imaging-Guided Biopsy

When an abnormality is identified as potentially malignant, a biopsy is needed to either confirm or rule out a cancer diagnosis. This involves taking a sample of the suspicious tissue so it can be closely examined and correctly identified in a lab. The real-time imaging that ultrasound provides is useful in helping to ensure that the appropriate area is sampled to allow for an accurate result.
