Diagnostic Mammography 
A diagnostic mammogram is performed for women who have a history of breast disease or who are experiencing new symptoms. It is also used when the radiologist sees an abnormality on a screening mammogram.
During a diagnostic mammogram, more pictures are taken to carefully study the breast condition. In most cases, special images involve magnification to make a small area of suspicious breast tissue easier to evaluate. Many other types of X-ray pictures can be obtained, depending on the type of problem and its location in the breast. These X-rays are tailored to meet the patient’s needs.
