Definitions for "Calcifications"
Deposition of calcium phosphate or oxalate crystals in the breast, detectable in mammograms. Histologic granular/amorphous-type calcifications formed by deposition of calcium on nuclear debris are often present in ductal carcinoma in situ with necrosis. These form linear, branching patterns on X-rays. Radiologists use the American College of Radiology Breast Imaging Reporting and Data System (BIRADS) classification to describe calcifications.
Tiny mineral deposits in the breast (considered Micro-calcifications if 1/50 of an inch)
Small calcium deposits within the breast, singly or in clusters, that are usually found by mammography. These are also called microcalcifications and macrocalcifications. They are a sign of change within the breast that may be monitored by additional, periodic mammograms, or by immediate or delayed biopsy. They may be caused by benign (non-cancerous) breast conditions or by breast cancer.
