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 small calcium deposits that look like white specks on a mammogram. Microcalcifications are usually not a result of cancer. But if they appear in certain patterns and are clustered together, they may be a sign of precancerous cells or early breast cancer.
