Mammograms

A mammogram is a specialized X-ray of the breast. Each breast is imaged with two views (top to bottom, side to side). While film X-rays are still used in some places, most breast imaging departments use digital technology. This allows them to store many more images in a smaller space and makes comparison to prior images easier. You can get mammograms at an imaging center or a breast center.

A screening mammogram is used to look for breast cancer when both a woman and her provider have no concerns about her breasts – when she is asymptomatic. In the United States, it is recommended that you have annual screening mammograms beginning at age 40. Screening mammograms may be done with tomosynthesis, or “3D” technology. This type of mammogram scans the breast in more detail than the standard 2-view approach. Tomosynthesis allows the radiologist to see more details and is especially useful when a woman has dense breasts. It’s important to have your screening mammograms compared to your prior ones, if possible. That way, the doctor can see how your breasts have changed over time. She can also see if there are any new features that need attention.

If the radiologist sees a change in the screening mammogram, she will request more views – diagnostic mammograms and possibly ultrasound.

A diagnostic mammogram is used when either you or your provider (including the radiologist) have a breast concern – when you are symptomatic. Diagnostic mammograms often require multiple views of the breast, concentrating on where you or your provider’s concerns are. Ultrasound may be used in addition to mammography.
