This article discusses the significance of microcalcifications on mammography and the changes in technology that have influenced management; it also describes a pragmatic approach to investigation of microcalcification in a UK screening programme. Microcalcifications result from the deposition of calcium oxalate and calcium phosphate within the breast tissue. The mechanism by which calcium deposition occurs is not clearly understood; it may be an active cellular process, or an effect of cellular degeneration. Calcification deposits are found within the ductal system, the breast acini, stroma and vessels, mainly as calcium oxalate and calcium phosphate.
Breast Microcalcifications on mammogram - Moose and Doc
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.
Breast calcifications are calcium deposits within breast tissue. They appear as white spots or flecks on a mammogram. Breast calcifications are common on mammograms, and they're especially prevalent after age 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. If breast calcifications appear suspicious on your initial mammogram, you will be called back for additional magnification views to get a closer look at the calcifications.
Breast calcifications are small deposits of calcium in the breast tissue. They often show up in mammograms and are most common in women over Breast calcifications are typically noncancerous, or benign. However, some forms can occasionally indicate breast cancer.
