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.
1 On the day of the examination, do not wear talcum powder, deodorant, lotion or perfume under your arms or on your breasts. 2  These substances can cause artifacts on your mammogram making the images harder to interpret (aluminum flecks in some powders and deodorants can mimic microcalcifications on the x-ray image).
