Nearly half of women have dense breast tissue, which can make it harder to see certain findings on a mammogram. That’s why many women benefit from supplemental screening to get a more complete picture.
Breast ultrasound is a comfortable, compression-free and radiation-free way to screen breast tissue and the underarm (axilla) area for abnormalities.
A complete screening ultrasound surveys both breasts and the axilla to look for abnormalities, often before you can feel anything.
Because density can mask cancers on mammography, ultrasound can add another way to evaluate tissue that may be harder to interpret on other modalities.
During your appointment, a probe glides over both breasts and the axilla area, without compression or discomfort.
The goal of screenings is to detect breast cancer early, when it is most treatable.
In studies, ultrasound showed ~90.9% sensitivity and 100% specificity for silicone implant rupture detection
Eliminating barriers to breast screenings is our mission. No prescription or referral from a doctor is required.
Breast ultrasound uses sound waves (not radiation) to create real-time images of breast tissue and the underarm (axilla) region. It can help identify findings such as solid masses or fluid-filled cysts, and it’s commonly used both as supplemental screening and as follow-up imaging when something needs a closer look.
Dense breasts are an independent risk factor for breast cancer. Risk-based screening is critical to being proactive about your breast care.
Levels of breast density are categorized by using the American College of Radiology's Breast Imaging Reporting and Data System. This is also known as BI-RADS. These levels are scored from A to D and describe the level of density:
Generally speaking, if you receive a mammogram report
says your breasts are heterogeneously or extremely dense,
then you are considered to have dense breast tissue.

On a mammogram, fatty breast tissue appears dark, making tumors (white areas) easier to see. In dense breasts, both normal tissue and tumors look white, which can hide cancers and make them harder to detect.
No. Ultrasound is a supplemental screening tool and works best alongside mammography and care from your healthcare provider.
Ultrasound can identify many types of breast abnormalities (including masses and cystic changes). If something looks suspicious, follow-up diagnostic imaging is recommended.
Yes, ultrasound is an effective tool for evaluating implant structure and surrounding tissue. For more information on breast ultrasound screening for implant integrity, click here.
No—no prescription or referral is required to schedule.
No. HerScan provides supplemental screening ultrasound and radiologist interpretation; it does not diagnose, treat, or prescribe for medical conditions. If findings are seen, follow-up with your healthcare provider is recommended.
At this time, HerScan does not accept Medicare, Medicaid, or any third-party insurance. Most FSA and HSA cards can be accepted, as long as they have a major credit card label on it.
