Are pregnant. Mammography uses radiation, but ultrasound does not. This makes it safer for the fetus.

Your healthcare provider may also use ultrasound to look at nearby lymph nodes, help guide a needle during a biopsy, or to remove fluid from a cyst. Breast ultrasound may miss small lumps or solid tumors that are commonly found with mammography. Being obese or having very large breasts may make the ultrasound less accurate. You may have risks depending on your specific health condition.
Be sure to talk with your healthcare provider about any concerns you have before the procedure. Your healthcare provider will explain the procedure to you. Ask any questions you have about the procedure. You may be asked to sign a consent form that gives permission to do the test.
Read the form carefully and ask questions if anything is not clear.
You do not need to stop eating or drinking before the test. You also will not need medicine to help you relax. You should not put any lotion, powder, or other substances on your breasts on the day of the test.
Wear clothing that you can easily take off. Or wear clothing that lets the radiologist or technologist reach your chest. The gel put on your skin during the test does not stain clothing, but you may want to wear older clothing. The gel may not be completely removed from your skin afterward. You may have a breast ultrasound as an outpatient or as part of your stay in a hospital. You will be asked to remove any jewelry and clothing from the waist up.

What are the benefits vs. What are the limitations of Ultrasound Imaging of the Breast? Which test, procedure or treatment is best for me? Ultrasound imaging of the breast produces a picture of the internal structures of the breast. Determining the Nature of a Breast Abnormality The primary use of breast ultrasound is to help diagnose breast abnormalities detected by a physician during a physical exam such as a lump and to characterize potential abnormalities seen on mammography or breast magnetic resonance imaging MRI. Ultrasound imaging can help to determine if an abnormality is solid which may be a non-cancerous lump of tissue or a cancerous tumor , fluid-filled such as a benign cyst or both cystic and solid.
Doppler ultrasound is used to assess blood supply in breast lesions. Supplemental Breast Cancer Screening Mammography is the only screening tool for breast cancer that is known to reduce deaths due to breast cancer through early detection.
Even so, mammograms do not detect all breast cancers. Some breast lesions and abnormalities are not visible or are difficult to interpret on mammograms. Breasts that are considered dense have a lot of glandular and connective tissues and not much fatty tissue, and that makes cancer harder to detect. Many studies have shown that ultrasound and magnetic resonance imaging MRI can help supplement mammography by detecting breast cancers that may not be visible with mammography. Your doctor can help you determine if either of these tests is appropriate for you.
MRI is more sensitive than ultrasound in depicting breast cancer, but MRI may not be available to all women.
If screening MRI is performed, then screening ultrasound is not needed, though ultrasound may be used to characterize and biopsy abnormalities seen on MRI. When ultrasound is used for screening, abnormalities not visible with mammography may be identified, including some that may require biopsy. Many of the abnormalities found with screening breast ultrasound are not cancer false positives.
See the Breast Cancer Screening page for more information. Ultrasound can be offered as a screening tool for women who: are at high risk for breast cancer and unable to undergo an MRI examination. Ultrasound-guided Breast Biopsy When an ultrasound examination reveals a suspicious breast abnormality, a physician may choose to perform an ultrasound-guided biopsy. Because ultrasound provides real-time images, it is often used to guide biopsy procedures.
An ultrasound exam will usually need to be performed before the biopsy in order to plan the procedure and to determine if this method of biopsy can be used. See the Ultrasound-guided Breast Biopsy page for more information. You will be asked to undress from the waist up and to wear a gown during the examination. Doppler sonography is performed using the same transducer.
What is Ultrasound Imaging of the Breast?
Most ultrasound exams are painless, fast and easily tolerated. Breast ultrasound is usually completed within 30 minutes. You may be asked to change positions during the exam. Benefits Most ultrasound scanning is noninvasive no needles or injections. Occasionally, an ultrasound exam may be temporarily uncomfortable, but it should not be painful. But there are occasions when your doctor might order a breast ultrasound instead of a mammography.

So, what is the difference? A breast ultrasound in a noninvasive the skin is not pierced procedure used to assess the breasts. Ultrasound technology allows a quick visualization of the breast tissues. Ultrasound may also be used to assess the blood flow to areas around the breasts. The examination is often used along with mammography — but in some cases it is used alone. Unlike mammography, breast ultrasound does not use radiation, and therefore poses no risk to pregnant women.

Not only may ultrasound be safely used during pregnancy, but is also useful to those have may have the presence of allergies to contrast dye. Breast ultrasound is generally not used as a screening toll for breast cancer detection because it does not always detect some early signs of cancer such as micro calcifications, which are tiny calcium deposits.
Ultrasound may be used in women for whom radiation is contraindicated, such as pregnant women, women younger than 30 years, and women with silicone breast implants. The procedure may also be used to guide interventional procedures such as needle localization during breast biopsies and cyst aspiration removal of fluid from cyst.
