Definition
By Mayo Clinic staffBreast calcifications are calcium deposits within breast tissue. They appear as white spots or flecks on a mammogram and are usually so small that you can't feel them.
Breast calcifications are common in all women and are even more prevalent after menopause. Although breast calcifications are usually noncancerous (benign), certain patterns of calcifications — such as tight clusters with irregular shapes — may indicate breast cancer.
On a mammogram, breast calcifications can appear as large white dots or dashes (macrocalcifications) or fine, white specks, similar to grains of salt (microcalcifications). Macrocalcifications are almost always noncancerous and require no further testing or follow-up. Microcalcifications are usually noncancerous, but certain patterns can be a sign of cancer. If calcifications are suspicious, further testing may be necessary.
