Macrocalcification

Breast calcification is a deposit of calcium in the breast tissue. Calcifications appear as tiny white spots on a mammogram. There are two types of breast calcification, macrocalcification and microcalcification. Macrocalcifications are large deposits and are usually not related to cancer. They are degenerative changes in the breast resulting from old injuries, inflammations, or aging of the breast arteries and are usually not related to cancer.
