- Associated with invasive breast cancer and DCIS
- Clustered, pleomorphic, in a ductal or linear distribution
- High grade DCIS – rod-shaped and branched. Also called casting or comedo microcalcifications – necrotic debris within ducts
Imaging
- Mammogram
- Most sensitive and recommended for picking calcifications
- Ultrasound
- Poor detection of microcalcifications and is not recommended for screening
- Differentials: skin calcifications (round, well defined, lucent centre, often bilateral and symmetrical), talcum powder
