How to check for breast cancer with breast imaging
Our radiologists understand the importance of an early breast cancer diagnosis. Our in-depth knowledge and expertise provide you with results you can trust. Screenings at Penn Medicine utilize the following breast imaging technology.
We rely on 3D mammography, also known as digital breast tomosynthesis, to look for cancer. This advanced technology uses low-dose X-rays to produce a three-dimensional picture of breast tissue.
A traditional 2D mammogram takes X-rays of the breast from top to bottom and side to side, while a 3D mammogram captures images in "slices" of the breast. The final images are more precise. They allow us to identify changes in breast tissue that may not be seen with a 2D image.
Typically, 3D mammograms cost the same as traditional mammograms and are covered by insurance.
Can't afford a mammogram? If you are uninsured or underinsured and over the age of 40, the Penn Medicine Breast Health Initiative offers free mammograms.
When a mammogram does not supply enough information about your breast, our expert radiologists use breast MRI (magnetic resonance imaging). A breast MRI does not replace a mammogram. When used together, these tests offer more comprehensive evaluation for patients who need it.
Breast MRI is most commonly used for high-risk patients, but it may also be used for other reasons. An MRI is more costly than a mammogram. Check with your insurance company about coverage for a breast MRI before having the test.
We use breast ultrasound as a complement to other screening tests or to investigate changes in the breast that can be felt but are not seen on a mammogram. This noninvasive technology uses sound waves to create images. If you are under the age of 30 and feel a lump in your breast, we may use ultrasound instead of a mammogram.
