Microcalcifications are tiny deposits of calcium salts that are too small to be felt but can be detected by imaging.[1]
They can be scattered throughout the mammary gland, or occur in clusters. Microcalcifications can be an early sign of breast cancer. Based on morphology, it is possible to classify by radiography how likely microcalcifications are to indicate cancer. [2]
In breast
Microcalcifications in the breast are made up of calcium phosphate or calcium oxalate. When consisting of calcium phosphate, they are usually dystrophic calcifications (occurring in degenerated or necrotic tissue).[3] Yet, the mechanism of their formation is not fully known.[4]
Calcium oxalate crystals in the breast may be seen on mammography and are usually benign, but can be associated with lobular carcinoma in situ.[5]
Microcalcification was first described in 1913 by surgeon Albert Salomon.[4]
