The Difference Between a Mammogram and an Ultrasound

Mammogram: The Key Differences. A mammogram uses a low dose of radiation to take an image of the breast. The tissue is compressed between two plates in order for the best image to be taken. An ultrasound uses high-frequency sound waves and converts them to an image.

Can you detect breast cancer with an 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.

Can you request an ultrasound instead of a mammogram?

A breast ultrasound isn't typically a screening tool for breast cancer. Instead, a physician might order an ultrasound, also called a sonogram, of the breasts if a screening mammogram produces unusual results. A physician might also use a breast ultrasound as a visual guide while performing a biopsy of the breasts.

Is it common to have an ultrasound after a mammogram?

Getting called back after a screening mammogram is fairly common, and it doesn't mean you have breast cancer. In fact, fewer than 1 in 10 women called back for more tests are found to have cancer. Often, it just means more x-rays or an ultrasound needs to be done to get a closer look at an area of concern.

What percentage of breast ultrasounds are cancer?

Like the first study, ultrasound was 100% effective at classifying a lump as benign without a biopsy. Most of the lumps classified as suspicious by ultrasound proved to be benign. Still, 25 women (2% of all women in the study) were diagnosed with breast cancer.

What color is breast cancer on an ultrasound?

Cancers are usually seen as masses that are slightly darker than the normal lighter gray fat or white (fibrous) breast tissue (Figs 9, 10). Sometimes distortion of the tissue or bright (white) echogenic dots due to calcifications can be seen.

What is usually the first sign of breast cancer?

A lump in the breast or in the armpits is often the first sign of breast cancer. This may be felt while in the shower. There may or may not be changes in the structure of the breast.

What is more accurate mammogram or ultrasound?

Breast ultrasound is more accurate than mammography in symptomatic women 45 years or younger, mammography has progressive improvement in sensitivity in women 60 years or older. The accuracy of mammograms increased as women's breasts became fattier and less dense.

Which is best mammogram or ultrasound?

Ultrasound is good at evaluating superficial lumps, but a mammogram is better able to note abnormalities deeper in breast tissue. Ultrasound doesn't show microcalcifications, the minute accumulation of calcium around a tumor and the most common feature seen on a mammogram.

How accurate are breast ultrasounds?

The sensitivity and specificity of ultrasound for detecting breast carcinoma was 57.1% and 62.8% respectively with a positive predictive value of 68.1%, a negative predictive value of 99.5%, a positive likelihood ratio of 39 and a negative likelihood ratio of 0.07.

What does it mean when you need an ultrasound after a mammogram?

When you're called back after a screening mammogram, “in most cases it means the radiologist wants to take a closer look at something so they can determine if there is something to be concerned about or not,” says Mark. This is especially true if it's your first mammogram.

What is the next step after a breast ultrasound?

The most likely next step is a diagnostic mammogram or breast ultrasound. In some cases, a breast MRI or a biopsy may be recommended. Here are the different types of follow-up tests: Mammography can be used as a follow-up test when something abnormal is found on a screening mammogram or CBE.

How long does it take to get the results of a breast ultrasound?

Breast ultrasound is usually completed within 30 minutes. If a Doppler ultrasound study is performed, you may actually hear pulse-like sounds that change in pitch as the blood flow is monitored and measured.
