Calcifications are small deposits of calcium that show up on mammograms as bright white specks or dots on the soft tissue background of the breasts. The calcium readily absorbs the X-rays from mammograms. Calcifications typically don't show up on ultrasounds, and they never show up on breast MRIs.
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 segmentthat drains into the nipple.
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.
Breast calcifications are deposits of calcium in the breast tissue. They are quite common and most are not associated with cancer. They are not related to the amount of calcium that you take in through your diet or supplements.
Electronic address: mmorgan rcsi. The implementation of mammographic screening programmes in many countries has been linked to a marked increase in early detection and improved prognosis for breast cancer patients. Breast tumours can be detected by assessing several features in mammographic images but one of the most common are the presence of small deposits of calcium known as microcalcifications, which in many cases may be the only detectable sign of a breast tumour.
Medically reviewed by Tari A. Breast calcifications are signs of cellular turnover — essentially, dead cells — that can be visualized on a mammogram or observed in a breast biopsy. In most cases, mammographic calcifications are associated with changes in benign normal breast tissue, though in some cases they can be a sign of early breast cancer.
Your mammogram breast X-ray from BreastScreen Aotearoa showed an area of calcifications, and you were asked to come back for assessment. The calcifications that showed up on your mammogram were not breast cancer. Breast calcifications are small areas of calcium in the breast.
The presence of microcalcifications in an initial screening may or may not be indicative of acute or potential breast cancer. Research as to the predictive value of different microcalcification presentations is ongoing. I just want to let you know that I have created a newer version of this page with more up-to-date information on Malignant Microcalcifications. However, this page is still pretty useful, so I would still use it for research.
