Calcifications On Breast Ultrasound Are Also Suspicious For Malignancy

3-D ultrasound for breast cancer

Mammography is more sensitive than ultrasound when it comes to the detection of microcalcifications. Calcifications on a solid mass which appear punctate are highly suspicious of malignancy and will usually appear on ultrasound as bright, punctate foci.

Since malignant breast lesions are typically either intensely or mildly homogeneous hypoechoic solid masses, on ultrasound this provides a background which makes it easier to view calcifications sonographically. So, while calcifications are usually not seen on ultrasound, when they do appear vividly, it is highly suspicious for malignancy.

Benign Indeterminate And Malignant Nodules

In a landmark study, Stavros et al established US criteria for characterizing solid breast masses. This work was facilitated by evolving technical improvements in US equipment that provided better resolution and images. They demonstrated that US may be used to accurately classify some solid lesions as benign, allowing follow-up with imaging rather than biopsy. They used high-resolution transducers, which were state-of-the-art at that time, and performed examinations in both radial and antiradial planes. The investigators also focused on the evaluation of suspected areas in the transverse and longitudinal planes.

Stavros et al proposed a US scheme for prospectively classifying breast nodules into 1 of 3 categories :

  • Benign

  • Indeterminate

  • Malignant

To be classified as benign, a nodule had to have no malignant characteristics. In addition, 1 of the following 3 combinations of benign characteristics had to be demonstrated:

  • Intense uniform hyperechogenicity

  • Ellipsoid or wider-than-tall orientation, along with a thin, echogenic capsule

  • 2 or 3 gentle lobulations and a thin, echogenic capsule

A nodule was classified as indeterminate by default if it had no malignant characteristics and none of the 3 benign characteristic combinations listed above.

To be classified as malignant, a mass needed to have any of the following characteristics:

  • Spiculated contour

  • Branch pattern

  • Microlobulation

Typical Us Patterns Of Specific Types Of Breast Carcinomas

What Does Breast Cancer Look Like On A Sonogram

The appearance of specific types of breast carcinoma have been studied. Although appearances vary greatly, some patterns are typical.

Mucin-containing carcinomas are often circumscribed but may have irregular margins. These lesions may be either hypoechoic or isoechoic relative to subcutaneous fat. In a study of these carcinomas by Conant et al involving 8 patients, US showed hypoechoic, solid masses in all of their cases. The lesions demonstrated acoustic shadowing or increased acoustic enhancement. Some lesions had circumscribed margins, and some were not circumscribed.

Tubular carcinoma is usually hypoechoic but is without circumscribed margins and acoustic posterior shadowing. Invasive ductal carcinoma typically appears as an irregularly shaped mass with spiculated margins with shadowing and architectural distortion of adjacent breast tissue. This lesion may contain malignant microcalcifications.

Invasive lobular carcinoma often does not cause a desmoplastic reaction. This type is frequently missed on mammography and may be difficult to see on sonograms. Butler et al reported that these lesions were ultrasonographically occult in 12% of their cases. In approximately 60% of cases, it appeared as a heterogeneous, hypoechoic mass with angular or ill-defined margins and posterior acoustic shadowing. In 15% of cases, US demonstrated focal shadowing without a discrete mass in 12% of cases, US showed a lobulated, circumscribed mass.

Positron Emission Tomography Scan

For a PET scan, a slightly radioactive form of sugar is injected into the blood and collects mainly in cancer cells.

PET/CT scan: Often a PET scan is combined with a CT scan using a special machine that can do both at the same time. This lets the doctor compare areas of higher radioactivity on the PET scan with a more detailed picture on the CT scan.

How Do I Get Ready For A Breast Ultrasound

  • 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.

  • Follow any other instructions your healthcare provider gives you to get ready.

How Does A Radiologist See Breast Cancer On Mammography & Ultrasound

When you look at mammography or ultrasound images, you might wonder how radiologists make any sense of them. How can they identify potential cancers in those Rorschach tests of gray and white? While even the most advanced imaging technology doesnt allow radiologists to identify cancer with certainty, it does give them some strong clues about what deserves a closer look. Today well discuss a few things that radiologists are on the lookout for when examining mammography and breast ultrasound images.

When radiologists look at a mammogram, theyre looking for three primary things:

  • Changes from what is seen in previous images
  • Calcifications
  • Masses

If youve had a mammogram before, it is helpful to give your current radiologist access to your previous mammography images. Anytime you visit a new mammography clinic, let them know where youve had breast imaging done in the past so they are able to note any changes over time.

Masses comprise a variety conditions, including cysts, benign solid tumors, and malignancies. Their size, shape, borders, and internal composition can give insight into whether they represent cancer. Cancerous tumors often appear as white masses with blurry or spiked borders, which indicate infiltration into the surrounding tissue. Cysts are often indistinguishable from solid tumors on a mammogram, so ultrasound is often used to determine whether a mass is solid or fluid filled .

What Are The Benefits Of A Breast Ultrasound

Diagnosing Breast Cancer with Ultrasound

Ultrasound examination allows the detection and identification of most breast lumps. It is especially useful in distinguishing between solid and fluid-filled lumps.

If the ultrasound does not identify a lump that you or your doctor can feel, then other tests, such as mammography or magnetic resonance imaging , may be required to examine the breast.

Why Might I Need A Breast 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. An example of early signs that may not show up on ultrasound are tiny calcium deposits called microcalcifications.

Ultrasound may be used if you:

  • Have particularly dense breast tissue. A mammogram may not be able to see through the tissue.

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

  • Are younger than age 25

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.

Your healthcare provider may have other reasons to recommend a breast ultrasound.

Symptoms For Specific Types Of Cancer

Each form of breast cancer develops in a different part of the breast and can affect different types of tissue.

Since many breast cancers cause no symptoms, people should attend regular screenings. This can help identify the disease in its early stages.

Below, we outline the types of breast cancer and their symptoms.

Posterior Acoustic Shadowing Is Suspicious For Breast Cancer

If a breast lesion shows posterior acoustic shadowing on ultrasound this means that there is something about the mass or around the mass which attenuates the sonic beam strength in comparison to normal adjacent tissues.

Posterior acoustic shadowing is suspicious for malignancy, but tends to be associated with low to intermediate grade breast tumors.

What may be happening is that a slow growing breast tumor causes a secondary desmoplastic response in the surrounding tissue. That means that dense fibrous and connective tissues are growing around the tumor as a kind of defense mechanism by the body to contain the neoplastic growth.

High grade malignancies in the breast grow too fast for this desmoplastic reaction to occur. However, posterior acoustic shadowing caused by a desmoplastic reaction can be found in benign breast neoplasms as well.

For example, fibrosis inside a tumor can block ultrasound from passing deeper, causing acoustic shadowing. But most benign tumors do not usually shadow unless they are calcified. So, again a biopsy may be necessary.

Results Of A Breast Ultrasound

Cool What Does Breast Cancer Look Like On Ultrasound

A radiologist will examine the images from your breast ultrasound and send the results to your primary care doctor, if you have one.

The images that a breast ultrasound produces are in black and white. Cysts, tumors, and growths will appear as dark areas on the scan.

However, a dark spot on your ultrasound doesnt mean that you have breast cancer. Most breast lumps are benign, or noncancerous.

Several conditions can cause benign lumps in the breast, including:

Signs Of Benign Breast Masses

In contrast to breast cancer tumors, benign lumps are often squishy. They may feel like a soft rubber ball with well-defined margins. They’re often easy to move around and may be tender.

Infections in the breast can cause redness and swelling. Sometimes it can be difficult to tell the difference between mastitis and inflammatory breast cancer, but mastitis often causes symptoms of fever, chills, and body aches. Those symptoms aren’t associated with cancer.

Breast Ultrasonography And Magnetic Resonance Imaging

Breast ultrasonography can be used to distinguish between solid and cystic masses in the breast. It can be used to evaluate a focal mass identified on a mammogram or a palpable mass. It is also used as an adjuvant for biopsy. Because of its low specificity, it is not thought to be a good modality for screening. It cannot replace mammography because it has no ability to detect microcalcifications. Ultrasonography can complement mammography in young women with dense breasts because dense breasts limit the accuracy of the mammogram.

Magnetic resonance imaging has a high sensitivity for the detection of breast cancer, and it is not affected by breast density. Screening studies to date have been done in high-risk patients, primarily those at risk because of known or suspected BRCA mutations or a family history of breast cancer. A systematic review by Warner and colleagues in 2008 identified 11 prospective studies of MRI screening. In the systematic review, MRI’s sensitivity was 75%. Combining mammography and MRI increased the sensitivity to 84%. The specificity of MRI was comparable but marginally lower than the specificity of mammography . These studies on the use of MRI for surveillance of women at high risk for hereditary breast cancer have demonstrated a substantial benefit for breast cancer detection.

The optimal point in time to perform the MRI in relation to mammography has not currently been determined.

Breast Ultrasound Sometimes Detects Abnormal Axillary Lymph Nodes

Sometimes a breast ultrasound will pick up an enlarged node in the axilla. Many breast cancer oncologists would take an enlarged axillary node on ultrasound as proof positive for lymph node metastasis, even without a lymph node dissection. . There is also a very small chance that enlarged lymph node could be a breast lymphoma.

How Is The Procedure Performed

Ultrasound use for Diagnosing breast cancer

You will lie on your back or on your side on the exam table. The sonographer may ask you to raise your arm above your head.

The radiologist or sonographer will position you on the exam table. They will apply a water-based gel to the area of the body under examination. The gel will help the transducer make secure contact with the body. It also eliminates air pockets between the transducer and the skin that can block the sound waves from passing into your body. The sonographer places the transducer on the body and moves it back and forth over the area of interest until it captures the desired images.

There is usually no discomfort from pressure as they press the transducer against the area being examined. However, if the area is tender, you may feel pressure or minor pain from the transducer.

Doctors perform Doppler sonography with the same transducer.

Once the imaging is complete, the technologist will wipe off the clear ultrasound gel from your skin. Any portions that remain will dry quickly. The ultrasound gel does not usually stain or discolor clothing.

Review Of The Literatureautomated Screening Breast Ultrasound And Integrating Sbu Into Clinical Practice

Although studies have shown screening breast ultrasound in women with dense breast tissue to be effective in detecting mammographically occult predominantly small node- negative breast cancer, several barriers exist limiting its implementation as a screening modality. Handheld screening ultrasound, requires a great deal of resources to screen large numbers of women as the scanning is performed by the technologist. Furthermore, the identification of the sonographically detected abnormality is made by the technologist. Furthermore, the time, required for a bilateral handheld whole breast ultrasound, can range from 10 to nearly 20 min, making it challenging to implement in a clinical practice .

In a large cohort study of 1886 women, Vourtsis and colleagues found ABUS to be comparable to hand-held ultrasound the overall agreement between the two modalities was found to be 99.8%. Moreover, ABUS seemed to outperform hand held ultrasound in the detection of architectural distortion, particularly with the use of the coronal plane .

Palpation Of Cancerous Masses

Cancerous masses in the breast are often very firm, like a rock or a carrot, and have an irregular shape and size. They are often fixedthey feel like they are attached to the skin or nearby tissue so that you cant move them around by pushing on thembut can be mobile. Theyre also not likely to be painful, though they can be in some cases.

On exam, other changes may be present as well, such as dimpling of the skin or an orange-peel appearance, nipple retraction, or enlarged lymph nodes in the armpit.

One type of breast cancer, inflammatory breast cancer, does not usually cause a lump but instead involves redness, swelling, and sometimes a rash on the skin of the breast.

How Is A Breast Ultrasound Done

Most often, ultrasound is done using a handheld, wand-like instrument called atransducer. First a gel is is put on the skin and/or the transducer, and then the transducer is moved around over the skin. It sends out sound waves and picks up the echoes as they bounce off body tissues deeper under the skin. These echoes are made into a picture on a computer screen. You might feel some pressure as the transducer is moved around on your skin, but it should not be painful.

Automated breast ultrasound is an option at some imaging centers. This technique uses a much larger transducer to take hundreds of images that cover nearly the entire breast. ABUS might sometimes be done as an added screening exam for women who have dense breasts. It might also be used in women who have abnormal findings on other imaging tests or who have breast symptoms. When ABUS is done, a second handheld ultrasound is often needed to get more pictures of any suspicious areas.
