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.
For this reason, people should avoid applying any skin products before bteasts screening. Because calcifications are so small, a mammogram is often used to locate them accurately. There are two types What is calcification of breasts breast calcification. Because of this, you may need further tests to Expanding anal rectal what sort of calcifications you have. Are there different types of breast calcifications? In select cases, your doctor might examine the area first using ultrasound or MRI. Further tests could include the following: Mammogram You may need to have another mammogram that gives a close-up magnified picture of the affected area.

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.

MGUS monoclonal gammopathy of unknown significance is a non-cancerous condition where the body makes an abnormal protein, called a paraprotein. You then have a small operation to remove the area of calcification.

Breast Calcifications | Cleveland Clinic
Breast calcifications are small clusters of calcium deposits that develop in breast tissue, most commonly in women over They are too small to feel, but can show up on a mammogram as small, bright, white spots. While calcifications are usually harmless, they can be a sign that a woman is at risk for developing breast cancer and needs more testing.
For instance, if the cluster of calcifications is tight or they are noted to present as lines of tiny calcifications, the radiologist may recommend additional mammogram images for further testing. The patient can talk to her doctor to learn more about her specific situation. It is not known what causes calcifications to develop in breast tissue, but they are not caused by eating too much calcium or taking too many calcium supplements.
They are seen on mammograms of about half of all women over age However, they also are seen in about 10 percent of mammograms on younger women. Women who have had breast surgery for any reason or who have injured their breasts, such as in a car accident, seem to be at higher risk for developing calcifications, as are women who have been treated for breast cancer in the past.
Calcifications may also occur within vessels in the breast related to older age or from a past infection in the breast tissue. Most women who have breast calcifications do not have any symptoms. They typically only learn they have them from a routine mammogram. Cleveland Clinic is a non-profit academic medical center. Advertising on our site helps support our mission.

Breast Calcifications Breast calcifications are clusters of calcium that develop in the breast. Usually painless, they are found on routine mammograms.
This condition is more common in women over age Calcifications can be a sign that a woman is at risk for developing breast cancer. Appointments What are breast calcifications? What causes breast calcifications? What are the symptoms of breast calcifications? Are there different types of breast calcifications? There are two types of breast calcification. Macrocalcifications : These appear as round and large bright white spots on a mammogram randomly scattered throughout the breast tissue.
This is the most common type. They are typically not related to cancer and usually do not need follow up. Microcalcifications : These are smaller white spots on a mammogram. While these can be randomly scattered as well, they are sometimes grouped together and can be a sign of cancer.
If your mammogram finds microcalcifications, your doctor will note any change in their appearance over time and probably order more tests. Show More.
