What causes breast calcifications?

Researchers don’t know what causes calcifications, but several possible explanations exist. Calcium deposits form in response to various processes affecting your breast tissue. Benign breast calcifications are associated with:

  • Breast injury.
  • Breast cysts.
  • Breast infections.
  • Aging arteries in your breast.
  • Benign breast lumps (fibroadenomas).
  • Mammary duct ectasia.
  • Previous breast surgery.
  • Previous breast cancer treatment.

Cancerous breast calcifications are often related to ductal carcinoma in situ (DCIS). DCIS is a non-invasive form of breast cancer that forms in your milk ducts. Non-invasive means that cancer hasn’t spread beyond your milk ducts.
