What are the chances of microcalcifications being cancerous?
”Probably benign” calcifications have a less than 2% risk of being cancer. In other words, about 98% of the time, these type of calcifications are considered not to be cancer. Typically, they will be monitored every six months for at least one year. Are most microcalcifications benign? • Microcalcifications are small and may appear in clusters.
How often are microcalcifications malignant?
They are less concerning if they are scattered throughout an entire breast or even both breasts. Some radiologists consider five or more calcifications in a cluster to be possibly suspicious of an underlying cancer. However, this is not a definite cutoff number — others recommend additional testing even if there are fewer than five in a cluster.
Can microcalcifications be cancerous?
Microcalcifications can also give an idea of the extent of the disease. They are usually noncancerous, although some patterns can be a sign of cancer. Information about the size, density, and distribution of breast microcalcifications can give an idea about the benign or malignant nature of the cancer.
Do breast calcifications mean that I have breast cancer?
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.
What if my breast calcifications are malignant?
Although breast calcifications are usually noncancerous (benign), certain patterns of calcifications — such as tight clusters with irregular shapes and fine appearance — may indicate breast cancer or precancerous changes to breast tissue.
What stage cancer are microcalcifications?
Are breast calcifications a sign of cancer? They're often benign, but calcifications can sometimes be an early sign of breast cancer. “The most common form of cancer we see with calcifications is ductal carcinoma in situ, which is considered stage 0 cancer,” Dryden says.
Can microcalcifications be advanced cancer?
Microcalcifications (the smaller type of calcifications) can sometimes put women at an increased risk of developing breast cancer. If microcalcifications occur in small lines or small clusters, a woman might be at increased risk of developing breast cancer.

Are microcalcifications always DCIS?
Calcifications can be due to DCIS. However, not all calcifications are found to be DCIS. Many women develop benign (not cancer) calcifications in their breasts as they get older. If you have calcifications, further mammograms will be done to see the calcifications in more detail.
What is the procedure to remove calcified breast tissue?
A surgeon will perform the biopsy in an operating room under local or general anesthesia. Prior to the surgical procedure, a radiologist may use X-rays to identify the calcified breast tissue and will then mark the tissue to be removed -- with either a thin wire or with dye.
What is calcification in breast?
Breast calcifications are small calcium deposits that develop in a woman's breast tissue. They are very common and are usually benign (noncancerous). In some instances, certain types of breast calcifications may suggest early breast cancer. There are two types of breast calcifications: macrocalcifications and microcalcifications.
Can calcium cause calcification in breast?
A number of factors can cause calcification in a woman's breast, including normal aging, inflammation, and past trauma to the area. Calcium from your diet does not cause breast calcifications.
Is microcalcification a cancer?
Microcalcifications are small calcium deposits that look like white specks on a mammogram. Microcalcifications are usually not a result of cancer.
Can calcifications be seen on a mammogram?
Breast calcifications do not cause symptoms, as they are too small to be felt during a routine breast exam. Usually, breast calcifications are first noticed on a mammogram.
What is the classification of calcifications on mammograms?
The American College of Radiology (ACR) Breast Imaging Reporting and Data System (BI-RADS) classifies calcifications on mammograms into three categories: typical benign, intermediate concern and higher probability of malignancy, according to types and distribution of calcifications.
What is benign calcification?
Benign calcifications are typically larger, coarser, round with smooth margins and have a scattered or diffuse distribution. Malignant calcifications are typically grouped or clustered, pleomorphic, fine and with linear branching.
Why are calcifications important?
However, calcifications are important because they can be the first and earliest sign of malignancy. For detection and analysis of microcalcifications, high-quality images and magnification views are required.

What is suspicious breast cancer?
If the distribution of the microcalcifications is linear and they are in round, oval, or amorphous form, they are termed as ‘suspicious’. Radiologists usually term a variable distribution density where the breast microcalcifications are closely packed at one place and widely spread at another as ‘suspicious’, and not definitive, for cancer.

The two types of breast calcifications are microcalcifications and macrocalcifications.
How are breast calcifications diagnosed?
Calcifications may appear as bright white spots on mammograms. You can't feel them from the outside, so the only way to detect them may be through a mammogram.
When breast calcifications are a sign of cancer
Microcalcifications in a certain pattern may signal cancer, because when breast cells are growing and dividing, they make more calcium. So, if there’s an area of the breast where this growth is occurring, the calcium deposits would be grouped together.
What's next?
If you have microcalcifications, your doctor may order another mammogram, or a biopsy, or he or she may wait to order another mammogram after six months.
