Microcalcifications show up on mammograms as tiny, salt-like white specks. They are not of particular concern unless they display certain patterns throughout the breast, in which case they may indicate a precancerous condition or even an early stage of breast cancer. In such a case, a doctor may call for a needle biopsy or stereotactic biopsy, and if those results indicate the presence of a low-grade tumor, a surgical biopsy may follow.
