Breast Arterial Calcification on a Mammogram: What It May Mean for Heart Health
A mammogram sometimes reveals calcium deposits in small arteries within the breast. This is called breast arterial calcification, or BAC. If the finding appears in a radiology report, it can raise important questions about overall cardiovascular health.
What is breast arterial calcification?
BAC involves calcification in the arterial wall of blood vessels in the breast. Its appearance and biology differ from the calcified atherosclerotic plaque measured by a coronary artery calcium CT scan. BAC itself is generally an incidental vascular finding and is distinct from breast calcifications evaluated for cancer.
Does BAC mean I have coronary artery disease?
A BAC finding alone does not diagnose blocked coronary arteries or prove that someone has had a heart attack. Observational studies have found associations between BAC and future cardiovascular events. The strength and practical implications of those associations differ among populations, and more work is needed to define the best response to an incidental report.
What should I discuss with a clinician?
Share the exact mammography report. Ask whether your blood pressure, cholesterol, diabetes status, tobacco exposure, kidney health, family history and other cardiovascular risk factors have been assessed. A clinician may consider standard primary prevention risk assessment and whether additional testing is warranted by the full clinical context.
Does everyone with BAC need a coronary calcium scan?
BAC alone does not automatically establish an indication for coronary CT. Decisions about coronary artery calcium scoring should be individualized using established prevention criteria, including age, symptoms, known cardiovascular disease, estimated risk and whether the result would influence treatment.
Can a virtual cardiology visit help?
A virtual preventive cardiology consultation may provide an opportunity to review an available report and discuss broader cardiovascular risk. The clinician may request additional records or local testing when indicated. A mammogram report should be communicated through a secure clinical pathway.
Frequently asked questions
Is BAC the same as a finding suspicious for breast cancer?
BAC refers to vascular calcification and is separate from the categories radiologists use to investigate potentially malignant breast findings. Follow your breast imaging team's recommendations for every finding on the report.
Should I start aspirin because BAC appeared on my mammogram?
The presence of BAC alone does not determine aspirin eligibility. The benefits and bleeding risks of preventive medication should be reviewed individually.
