Breast Cancer Treatment at Siteman Cancer Center

The Siteman Cancer Center is the only National Cancer Institute-designated Comprehensive Cancer Center in Missouri. U.S. News and World Report consistently ranks us among the top cancer centers in the nation.

The breast cancer team at Siteman is made up of Washington University Physicians who focus on cancers of the breast. Together, they see more than 1,000 new breast cancer patients a year. This high volume of patients means that our physicians have more experience than most community practitioners. When you’re treated at Siteman, you benefit from the combined expertise of the many physicians who specialize in your disease, including radiologists, pathologists, surgeons, radiation oncologists and medical oncologists.

Our breast cancer physicians are actively involved in clinical studies that investigate new surgical procedures, chemotherapy regimens, immunotherapy, targeted therapies and vaccines. Having your cancer treated at Siteman gives you access to new therapies that are as good as – or potentially better than – current standard therapies available elsewhere.

Plastic and reconstructive surgeons are an important part of the breast cancer team at Siteman. These surgeons work closely with cancer surgeons to provide the best reconstructive outcomes.


It matters where you go. At Siteman, every mammogram is read by radiologists that sub-specialize in comprehensive breast imaging. That means 100 percent of the time these specialists are dedicated to interpreting breast images.

All of our radiologists are full-time Washington University physicians affiliated with the internationally recognized Mallinckrodt Institute of Radiology.

At Siteman we provide all digital breast imaging services including:

  • Screening
  • 3D mammography (tomosynthesis)
  • Diagnostic mammograms
  • Breast ultrasound
  • Breast Magnetic Resonance Imaging (MRI)
  • Minimally invasive breast biopsy
