A diagnostic mammogram differs from a screening mammogram in that it’s used for women who have noticed worrisome changes in their breasts, or had abnormal screening mammograms and need additional evaluation. If you feel a new lump, have noticed nipple discharge in one breast– of any color– or have any other new problems that concern you, your doctor will order a diagnostic mammogram instead of a screening mammogram. Diagnostic mammograms may include only the four standard mammogram pictures (two views of each breast) or could include specialized images like magnification or spot compression views. Ultrasound is frequently used in combination with diagnostic mammography.
