Mammogram - calcifications: MedlinePlus Medical Encyclopedia
The same goes for any powders, creams, or lotions applied under the arms, in the chest area, or on the breast skin. You might be told that deodorant and other skin products can affect the quality of the images. But why is that, exactly? Many deodorants contain metallic substances — aluminum is a common culprit — and on a mammogram, their dense particles can look just like calcifications. Calcifications are small deposits of calcium that show up as bright white specks or dots on the soft tissue background of the breasts because the calcium absorbs the X-rays from mammograms. Calcifications are a sign of some underlying process that is happening in the breast tissue. Tissue injury or infection, cysts or other benign non-cancerous growths, and even simple aging are common causes of calcifications.
