Welcome to the future in breast cancer detection.

It’s called 3D mammography and Columbia St. Mary’s exclusively offers this advanced technology at all of our mammography locations.

The benefits of 3D mammography are numerous and well established.

A study published in the Journal of American Medical Association (JAMA) looked at 454,850 breast screening examinations and found:

- 3D mammography detects 41 percent more invasive breast cancers.

- 3D mammography decreases the rate of false positives by up to 40 percent. 

This means that cancer is caught earlier and patients often require less treatment and suffer fewer side effects.

And, far fewer women will experience the stress and anxiety that accompanies a call-back appointment for further examination.

This transformation was made possible for ALL patients at no additional charge through the commitment of $1 million from Columbia St. Mary's Foundation and the generosity of its donors. 

Today, 3D mammography screenings are available at CSM Hospital Milwaukee (Van Dyke Haebler Center), CSM Hospital Ozaukee, River Woods Outpatient Center (Glendale), Gateway Medical Clinic (West Allis), and Marsho Family Medical Group (Sheboygan).

Additionally, this technology is available on Columbia St. Mary's unique mobile mammography coach, which serves many of our clinics and offers free mammograms to underserved patients in rural and inner-city areas.

Improvements through this technology is accomplished because 3D mammography allows the radiologist to view multiple slices through the breasts as thin as 1 mm. This eliminates the overlapping of dense breast tissue that can obscure a significant finding or, in some cases, give the false impression of an abnormality when none is present.

From the patient’s perspective, the 3D mammogram is performed similarly to the standard 2D mammogram. The exam requires compression and the exposure is obtained with the patient holding her breath to decrease movement. The X-ray tube moves through a 15-degree arc during a four-second exposure obtaining 15 projection images. The numerous images are then reconstructed and presented to the radiologist for interpretation.


Columbia St. Mary's had the foresight to invest in this technology because breast cancer remains a major health concern in our country, with women facing a 1-in-8 lifetime risk for the disease.

Fortunately, thanks to increased awareness and improved treatment and detection – such as 3D mammography – most women survive.

When it comes to successfully fighting breast cancer, early detection is and always has been a woman’s best weapon.

But if cancer is diagnosed, Columbia St. Mary's patients can rest assured they will receive the best care possible.

From technologists, physical therapists and nurses to dedicated breast radiologists, pathologists, surgeons, radiation oncologists and medical oncologists, the cancer caregivers at Columbia St. Mary’s work together to care for each patient as an individual.  

Columbia St. Mary’s has been a leader in breast care in southeastern Wisconsin for decades, and the introduction of 3D mammography ensures we will continue to be for decades to come.

You can partner with this expert team of caregivers to help care for Columbia St. Mary's patients.

When you make a gift, you help ensure that technology like 3D mammography is available to everyone in our community.
