Calcifications: Calcifications are tiny flecks of calcium â like grains of salt â in the soft tissue of the breast that can sometimes indicate the presence of an early breast cancer. Calcifications usually can't be felt, but they appear on a mammogram. Depending on how they're clustered and their shape, size, and number, your doctor may want to do further tests. Big calcifications â macrocalcifications â are usually not associated with cancer.
Calcifications can also occur in the glandular tissue where milk is produced (the lobules) and in the ducts that carry milk to the nipple. Even when you're not pregnant or breastfeeding, the lobules secrete small amounts of calcium-containing fluid. If that calcium crystallizes, it may show up on a mammogram.enign breast calcifications can form as a response to injury. When any part of the breast is damaged â by surgery, radiation, trauma, infection, or a cyst â fat cells die, releasing fatty acids that combine with calcium to form deposits.
