Learn more about services at Mayo Clinic.Breast calcifications Calcifications are small buildups of calcium, called calcium deposits, in the breast. They show up as white spots on a mammogram. Large, round or well-defined calcifications (shown left) are more likely to not be cancer, also called benign. Tight clusters of tiny, fine, irregularly shaped calcifications (shown right) may mean cancer.
