diagnostic mammogram
(DY-ug-NAH-stik MA-muh-gram)
An x-ray picture of the breast used to check for breast cancer after a lump or other sign or symptom of the disease has been found. It is also used to follow up on a suspicious change found during a screening mammogram. A diagnostic mammogram usually involves taking more detailed x-ray pictures of the breast from different angles to check the suspicious area more closely.
