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.
Microcalcifications are tiny specks of calcium in the breast. Microcalcifications seen on a mammogram are of more concern than macrocalcifications, but they do not always mean that cancer is present. The shape and layout of microcalcifications help the radiologist judge how likely it is that cancer is present.icrocalcifications are tiny specks of calcium in the breast.
