1 in 5 Women

One in five women who undergo breast-conserving surgery, sometimes referred to as a lumpectomy, due to a breast cancer diagnosis, will be called back for a second surgery or re-excision, due to positive margins1. In fact, some studies show that this rate of re-excision could even be as high as 90% in some centers.

So what is a positive margin?

The goal at the end of surgery is to have negative margins, meaning the surgeon removed all of the cancer in the initial surgery. However, many patients (1 in 5 on average) are told that, after-surgery, the final pathology report indicated that the specimen removed was found to have positive margins. This means that not all the cancer was removed during the initial surgery, and that the patient will need to come back in for a second surgery to complete the operation.

What is The MOZART® System?

3D Mammography for Your Surgery

When used in the OR during breast-conserving surgery, the MOZART System uses 3D imaging technology to give your surgeon a more detailed view of your cancer. This technology enables your surgeon to see if all the cancer is removed before finishing the operation. This is how the MOZART System helps the surgeon avoid that second surgery.

Consider the MOZART System as 3D Mammography for the Operating Room.

Studies Show The MOZART System Improves Surgical Outcomes

“The use of The MOZART System decreased re‑excision rates by more than half.”2

Why Is This Important? The Cost of Re‑excisions

Patients who have a re‑excision are 2‑8x more likely to have their cancer come back at a later date4.

Patients who have a re‑excision are 2x more likely to experience surgical infections5.

Patients who have a re‑excision are 49% more likely to experience surgical complications5.

Patients who have a re‑excision are more likely to experience a decrease in satisfaction with their surgery6.
