Should doctors report all health-related findings detected during routine medical screenings?
Maryland has enacted a law requiring radiologists to notify patients when mammograms reveal breast arterial calcifications. While these deposits are unrelated to breast cancer, they can serve as an important indicator of a patient's potential cardiovascular health.
Why it matters
Identifying these calcifications allows for earlier conversations about heart health in a country where more than 60 million women currently live with some form of heart disease. Research suggests these findings may provide a crucial, previously overlooked warning sign for cardiovascular events.
A study of 25,000 women found an 82% higher risk of future cardiovascular events for those with breast arterial calcifications. This finding highlights a clear, population-level association between these vascular deposits and heart health.
The players
Northwell Health
A large New York-based health system that provides integrated clinical care and research across numerous specialties, including cardiovascular health.
The details
Breast arterial calcifications are mineral deposits found within the blood vessels of the breast tissue. When detected during a standard mammogram, these deposits can indicate systemic arterial stiffening. Northwell Health, which implemented similar reporting in 2024, identified these calcifications in approximately 13% of the 88,000 mammograms reviewed between January and October of that year.
Timeline
Northwell Health began reporting breast arterial calcifications in early 2024.
Northwell reported results on 88,000 mammograms between January and October 2024.
The Maryland law requiring breast arterial calcification reporting took effect on October 1, 2026.
Health Landscape
This mandate follows the broader trend of integrating incidental cardiovascular screening into standard imaging protocols. It reflects an evolving approach to using common screenings to capture data beyond their primary diagnostic purpose.
If you receive a mammogram report noting breast arterial calcifications, it is worth discussing the finding with your doctor to assess your broader heart health. These calcifications are not linked to cancer, but they may prompt a conversation about your cardiovascular risk factors.
The takeaway
Breast arterial calcifications identified on a mammogram are an incidental finding that may suggest an underlying risk for cardiovascular disease. If your report mentions them, schedule a check-up with your primary care physician to review your cardiovascular risk profile.
