title: [Calcifications visible in mammographic examination as a diagnostic problem].
abstract: Mammography can detect various types of calcification in the breast. Their correct estimation enables detection of the breast cancer in situ. In our research there have been analyzed various types of calcification available on radiograms, which have been placed in publications. The aim was to find out which of them could be characteristic for cancer. Calcifications that are seen in mammography can be divided into: microcalcifications, macrocalcifications in galactophorous ducts, in blood and sympatic vessels. Pathogenesis of microcalcifications is not explained. There exist hypotheses which claim that they are caused by focuses of necrosis, changes in acid mucopolysaccharides in the midst of galactophorous ducts or in mitochondria. Differentiation between microcalcifications and macrocalcifications is based on variations in size, shape and radiological changes which they accompany.
