In this article, we look at the causes of breast calcifications, and we discuss what may happen if they show up on a screening test. Calcifications are small calcium deposits that develop in the breasts. They do not cause symptoms, and it is not possible for a doctor to diagnose them from a routine breast check. Instead, they typically appear on a mammogram — an X-ray of the breasts — as white dots. Other breast scans, such as ultrasounds or MRI scans , do not show up calcifications.
Calcifications are small Rubber stamp sheets of calcium that show up on mammograms as bright white specks or dots on the soft tissue background of the breasts. The most important feature of hWat calcifications is the apparent change in shape of the calcific particles on different mammographic projections craniocaudal versus oblique or 90? This content does not have an Arabic version. The images show a different shape on the oblique view compared to the mediolateral view. Your doctor will monitor them for changes that could suggest cancer.

Breast calcifications are very common. They are usually due to benign not cancer changes that occur as part of aging. Breast calcifications can develop in the blood vessels of the breast. Occasionally, breast calcifications can be an early sign of cancer. Because of this, you may need further tests to check what sort of calcifications you have.
The calcifications show up on a mammogram as small white dots. When calcifications are found, they will look carefully at:. They will categorise the calcifications as looking benign, indeterminate uncertain or suspicious of being cancer. Microcalcifications are small. They often occur because of benign not cancer changes, but occasionally microcalcifications can be an early sign of cancer.
Macrocalcifications are larger. They usually occur because of benign not cancer changes and do not need to be investigated. If the calcifications look benign, nothing more needs to be done. These tests are usually done in the breast clinic or x-ray department as an outpatient. You may need to have another mammogram that gives a close-up magnified picture of the affected area.
An ultrasound scan uses sound waves to produce an image of the breast tissue. A core biopsy uses a hollow needle to take a sample of breast tissue, and is done using a mammogram or ultrasound for guidance. The sample will be sent to a laboratory to be looked at under a microscope. Several tissue samples may be taken at the same time. This procedure will be done using a local anaesthetic. Because calcifications are so small, a mammogram is often used to locate them accurately.
A biopsy can then be taken from the affected area known as a stereotactic core biopsy. This procedure takes a little longer than a core biopsy and is done using a mammogram or ultrasound for guidance.
After an injection of local anaesthetic, a small cut is made in the skin. A hollow probe connected to a vacuum device is placed through this cut. Breast tissue is then sucked through the probe by the vacuum into a collecting chamber. This means that several samples of breast tissue can be collected without removing the probe. The samples are sent to a laboratory to be examined under a microscope.
Occasionally, you may have a vacuum assisted excision biopsy to remove an area of calcification. This is a similar procedure to a vacuum assisted biopsy, but more tissue may be removed.
Sometimes a small metal clip or marker may be placed in the breast where the biopsy has been taken. This is so the area can easily be found again if a further biopsy or surgery is necessary. The marker clip is usually made of titanium the same metal used for joint replacement surgery.
It will not set off alarms at airports. Most clips are now suitable for having an MRI, but if the marker clip is left in and you need to have an MRI scan in the future, let your doctor or radiographer know. You may also need an operation if the biopsy results show an unusual change called atypia , or the biopsy results show a sign of early cancer. In this case a technique called wire localisation is used. In the x-ray department, a mammogram or ultrasound scan will be used as a guide to insert a fine wire into the breast under local anaesthetic.
The wire is then carefully secured under a small dressing and left in place until the operation to remove the area of calcification. The operation is usually done under a general anaesthetic on the same day, and the wire will be removed during the operation. Some hospitals are using a new localisation procedure. Instead of a fine wire a tiny, very low dose radioactive seed about the size of a grain of rice or a small radiation-free magnetic marker known as a Magseed is inserted into the breast tissue.
This can be done up to two weeks before your operation. During surgery, a special probe is used to locate the seed and guide the surgeon to the tissue that needs to be removed. The seed will be removed during the operation. If the wire or seed feels uncomfortable while it is in place you can have mild pain relief, such as paracetamol. After your operation, you may feel soreness and discomfort but this can be managed with pain relief. There will be a scar, but this should fade in time.
If the calcifications are part of another benign breast condition or an unusual change called atypia , you will be told if anything else needs to be done. You may also find it helpful to read our information about benign breast conditions. Most breast calcifications are due to benign not cancer changes, which does not increase your risk of breast cancer. However, if the breast calcifications are due to atypical change, this may slightly increase your risk of breast cancer.

What is calcification of breasts. References
In this procedure, the doctor uses imaging to guide the process and make sure tissue from the suspicious area is sampled. A biopsy is not always needed if there are microcalcifications; sometimes close follow-up is all that's warranted.
While the presence of calcifications on a mammogram can sometimes alert doctors to breast cancers that would otherwise go undetected, experts are learning that breast calcifications also may provide information about the prognosis of breast cancer. According to a study , breast cancers that have microcalcifications are more likely to be HER2-positive , tend to have a higher tumor grade , are more likely to have spread to lymph nodes, and have a greater risk of recurrence.
This information may be helpful for women with early-stage breast cancers who are weighing the benefits of treatments such as chemotherapy after surgery. Calcifications believed to be in the arteries of the breast have traditionally been thought of as incidental findings not associated with breast cancer risk, so they didn't get much attention.
However, that's changing. Research suggests that the presence of breast arterial calcifications is associated with underlying coronary artery disease in women over 40 who don't have any symptoms of heart disease.
Their presence was even more likely to predict the presence of arteriosclerosis than risk factors such as high blood pressure , a family history of heart disease, and more. Unfortunately, symptoms of coronary artery disease or a heart attack in women are often different from what is considered "typical," and symptoms such as profound fatigue, nausea, or even jaw pain may be the only ones heralding these concerns. Mammograms may, by finding arterial calcifications, help in detecting coronary artery disease before problems occur.
Since much of the research looking at the meaning of breast arterial calcifications is relatively new, it's important to be your own advocate and ask questions if you should see a note about these on your report. Doctors do not always mention the word calcifications when talking to women about their mammograms. They may instead mention a "small abnormality.

Breast calcifications - Macmillan Cancer Support
The basic functional unit in the breast is the lobule, also called the terminal ductal lobular unit TDLU. The TDLU consists of acini, that drain into the terminal duct. The terminal duct drains into larger ducts and finally into the main duct of the lobe or segment , that drains into the nipple. The breast contains lobes, that each contain lobules. The terminal ductal lobular unit is an important structure because most invasive cancers arise from the TDLU.
It also is the site of origin of ductal carcinoma in situ DCIS , lobular carcinoma in situ, fibroadenoma and fibrocystic disease, like cysts, apocine metaplasia, adenosis and epitheliosis.
Most calcifications in the breast form either within the terminal ducts intraductal calcifications or within the acini lobular calcifications.
Lobular calcifications These calcifications fill the acini, which are often dilated. This results in uniform, homogeneous and sharply outlined calcifications, that are often punctate or round. When the acini become very large, as in cystic hyperplasia, 'milk of calcium' may fill these cavities. However when there is more fibrosis, as in sclerosing adenosis, the calcifications are usually smaller and less uniform.
In these cases it can be difficult to differentiate them from intraductal calcifications. Lobular calcifications usually have a diffuse or scattered distribution, since most of the breast is involved in the process that forms the calcifications.
Lobular calcifications are almost always benign. Intraductal calcifications These calcifications are calcified cellular debris or secretions within the intraductal lumen. The uneven calcification of the cellular debris explains the fragmentation and irregular contours of the calcifications.
These calcifications are extremely variable in size, density and form i. Sometimes they form a complete cast of the ductal lumen. This explains why they often have a fine linear or branching form and distribution. The diagnostic approach to breast calcifications is to analyze the morphology, distribution and sometimes change over time.
The form or morphology of calcifications is the most important factor in deciding whether calcifications are typically benign or not. If not, they are either suspicious intermediate concern or of a high probability of malignancy. Usually biopsy in these cases is needed to determine the etiology of these calcifications. The form of calcifications is the most important factor in the differentiation between benign and malignant.
If calcifications cannot be readily identified as typically benign or as 'high probability of malignancy', they are termed of 'intermediate concern or suspicious'. If a specific etiology cannot be given, a description of the calcifications should include their morphology and distribution using the descriptions given in the BI-RADS atlas 1.
Diffuse or scattered distribution is typically seen in benign entities. Even when clusters of calcifications are scattered throughout the breast, this favors a benign entity. Sometimes this differentiation can be made, but in many cases the differentiation between 'regional' and 'segmental' is problematic, because it is not clear on a mammogram or MRI where the bounderies of a segment or a lobe exactly are.
Clustered calcifications are both seen in benign and malignant disease and are of intermediate concern. When clusters are scattered througout the breast, this favors a benign entity. A single cluster of calcification favors a malignant entity. Linear distribution is typically seen when DCIS fills the entire duct and its branches with calcifications. There are conflicting data concerning the value of absence of change over time. It is said that the absence of interval change in microcalcifications that are probably benign on the basis of morphologic criteria is a reassuring sign and an indication for continued mammographic follow-up 2.
On the other hand in a retrospective study that included indeterminate and suspicious clusters of microcalcifications, stability could not be relied on as a reassuring sign of benignancy 3. It seems that the morphology of calcifications is far more important than stability and stability can only be relied on if the calcifications have a probably benign form.
In the same study it was shown that the odds for invasive carcinoma versus DCIS are statistically significantly higher among patients with increasing or new microcalcifications. The likelihood that carcinoma will be invasive increases significantly when a suspicious or indeterminate cluster of calcifications is new or increasing.
On the left a patient with a few heterogeneous coarse calcifications. At six month follow up they had increased in number and DCIS was found at biopsy. Many calcifications can be classified as typically benign and need no follow up i. Many of these are skin calcifications. These are usually lucent-centered deposits.
Atypical forms may be confirmed by tangential views to be in the skin. Usually they are located along the inframammary fold parasternally and in the axilla and areola. When you consider the possibility of dermal calcifications, always study the portion of the skin that is seen en face to look for similar calcifications arrow. Tatoo sign Skin calcifications may simulate parenchymal breast calcifications and may look like malignant-type calcifications.
The cluster calcifications on the left was presented for biopsy. During the vacuum assisted biopsy procedure it was not possible to biopsy these calcifications, because they were out of range.
When you look at the oblique and craniocaudal view, notice that the calcifications look exactly the same in configuration. This is called the tattoo sign. Spot views subsequently prooved that these were dermal calcifications.
Here another example of the tatoo-sign. First notice that there are some calcifications that are clearly located within the skin arrows. The cluster calcifications on the MLO-view has the exact configuration as the cluster on the CC-view next image. On the CC-view the configuration of the microcalcifications is exactly the same. If these calcifications were located in the centre of the breast they should have a different configuration, because the projection is different.
Only when calcifications are located within the skin their configuration stays the same. These are linear or form parallel tracks, that are usually clearly associated with blood vessels.
Vascular calcifications noted in women. On the left typical vascular calcifications. If only one side of a vessel is calcified arrow , the calcification may simulate intraductal calcification, but usually the diagnosis is straight forward.
The classic large 'popcorn-like' calcifications are produced by involuting fibroadenomas. These calcifications usually do not cause a diagnostic problem. When the calcifications in an fibroadenoma are small and numerous, they may resemble malignant-type calcifications and need a biopsy.
These are formed within ectatic ducts. These benign calcifications form continuous rods that may occasionally be branching. They may have lucent centers if the calcium is in the wall of the duct. These calcifications follow a ductal distribution, radiating toward the nipple and are usually bilateral.
These secretory calcifications are most often seen in women older than 60 years. Sometimes it is difficult to differentiate these from lineair calcifications as seen in DCIS.
Round calcifications are 0. When smaller than 0. Round and punctate calcifications can be seen in fibrocystic changes or adenosis, skin calcifications, skin talc and rarely in DCIS. Suspect DCIS when the calcifications are small, i.
These are round or oval calcifications that range from under 1 mm to over a centimeter. They are the result of fat necrosis, calcified debris in ducts, and occasional fibroadenomas. These are very thin benign calcifications that appear as calcium is deposited on the surface of a sphere. These deposits are usually under 1 mm in thickness when viewed on edge. Although fat necrosis can produce these thin deposits, calcifications in the wall of cysts are the most common 'rim' calcifications.
On the left a sharply defined lesion. The low density indicates the presence of fat. This is a typical oil cyst. On a follow up mamogram the wall has calcified resulting in eggshel calcifications. These are benign sedimented calcifications in macro- or microcysts. On craniocaudad views they appear as fuzzy, round or amorphous.
Consider magnification spot film with horizontal beam when you think of the possibility of milk of calcium, because on a 90? Many calcifications representing milk of calcium within microcysts however do not layer on horizontal beam radiographs. The most important feature of these calcifications is the apparent change in shape of the calcific particles on different mammographic projections craniocaudal versus oblique or 90? The images show a different shape on the oblique view compared to the mediolateral view.
On the mediolateral view there is layering of the calcium. On the craniocaudal image the calcifications are round, fuzzy and ill-defined.
On the mediolateral view the calcifications appear as semilunar, crescent shaped tea cups. They represent calcium deposit on suture material. They are typically linear or tubular in appearance and knots are sometimes visible. These are coarse irregular 'lava-shaped' calcifications.
These calcifications are larger than 0. They are seen in irradiated breast or following trauma.
