While some calcifications may indicate breast cancer, such as ductal carcinoma in situ (DCIS), most are noncancerous (benign) conditions. Benign causes of breast calcifications include:
- Previous injury or surgery to the breast (fat necrosis)
- Skin (dermal) or blood vessel (vascular) calcification
- Breast cysts
- Cell secretions or debris
- Mammary duct ectasia
- Previous radiation therapy for cancer
