n.
A tiny, nonpalpable deposit of calcium in breast tissue that is visible on a mammogram, can be scattered or clustered, and can indicate either cancer or benign tissue changes.

microcalcification

Imaging An aggregate of precipitated calcium salts, which by LM appears as purplish crystalline debris; MCs usually lack clinical significance, and occur in various tissues–eg, blood vessel walls in ASHD, or in necrosis; MCs appear on mammography as scattered or aggregated white dots, and are a 'soft' diagnostic criterion suggestive of breast CA

microcalcification

(mī″krō-kăl-sĭ-fĭ-kā′shŭn)
A minute deposit of calcium in breast tissue that can be detected with a mammogram but not felt on physical examination. A grouping of microcalcifications suggests that cancer may be present in the organ.
