3D Automated Breast Ultrasound System, or 3D ABUS, is a new, innovative breast screening tool developed by Invenia for women with dense breast tissue. This test is a comfortable and quick, and does not expose you to any radiation. When used in addition to mammography, ABUS can improve breast cancer detection by 35.7 percent over mammography alone.

If you have dense breast tissue, like 40% of women in the U.S., the addition of ABUS screening might be right for you. ABUS screening along with your screening mammogram will help provide a clear evaluation of your dense breast tissue.

We are now offering this test in our Plainview and Stony Brook offices.

 

Should I get an ABUS screening exam?

Breast Density — What does it mean?

Breasts are made of fat and breast tissue. Some women have more fat than breast tissue while others have more breast tissue than fat. When there is more breast tissue the breast is considered dense. On a mammogram dense tissue looks white. Since masses or lumps also appear white on a mammogram, a suspicious lump may be masked by the dense breast tissue.

Dense breast tissue is also linked with an increase in the risk of developing breast cancer. Women with extremely dense breast tissue have a 4 to 6 times greater risk of developing breast cancer than women who do not have dense breast tissue. ABUS helps physicians look differently at dense breast tissue.

Breast density is determined by the radiologist who reads your mammogram and classifies the density into one of four categories. Your doctor will tell you if you have dense breasts based on your mammogram’s classification on the density scale.

ABUS vs. Mammography

3D ABUS is completely different from mammography. A mammogram is a breast X-ray used to detect and evaluate breast changes. Unfortunately, mammograms are not perfect at finding breast cancer and can miss up to 1/3 of breast cancers in patients with dense breasts. Used in conjunction with mammography, 3D ABUS helps to provide a more comprehensive study.

What happens during the test?

The exam is simple, painless, and does not use any radiation. A layer of lotion is applied to the breast to ensure good contact between the 3D ABUS device and the skin. Then a curved panel is placed over the breast and gently flattens the tissue against the body. A 10-second preview scan is performed to determine the optimal settings for your exam. Then the actual scanning begins. Typically, three 60-second scans are performed on each breast. The entire procedure takes about 15 minutes.

Once all the images have been recorded, they will be sent to a radiologist who will review them along with your mammogram.

Invenia ABUS is the only FDA-approved system for breast cancer screening when used in combination with mammography in women who have dense breast tissue and no prior interventions. ABUS helps radiologists locate hidden cancers in dense breast tissue.
