Washington University Breast Cancer program focuses on the diagnosis and treatment of breast cancers of all stages and subtypes. Some of the diseases we treat are:

  • HER2 positive breast cancer
  • HER2-low breast cancer
  • Triple negative breast cancer
  • Estrogen receptor positive breast cancer
  • Metastatic breast cancer
  • Breast cancer bone metastasis
  • Breast cancer brain metastasis
  • Inflammatory breast cancer
  • Breast cancer in pregnancy
  • Male breast cancer
  • Ductal carcinoma in situ
  • Young women with breast cancer

The Treatment Approach of the program

We are dedicated to offering a comprehensive and personalized treatment approach to ensure that patients receive the highest level of care and support throughout their cancer journey. Our team of physicians collaborates closely with specialists from various disciplines, including radiation oncologists, surgical oncologists, primary care and subspecialty care physicians, pathologists, pain medicine specialists, medical geneticists, physical therapists, psychologists, and social workers. This collaborative effort ensures that our patients not only receive the most advanced cancer treatments but also benefit from the essential support necessary to navigate the physical and emotional challenges associated with a cancer diagnosis and treatment.

Challenging cases are presented during our weekly comprehensive multidisciplinary conferences. Treatment options that we offer include:

  • Chemotherapy
  • Hormonal therapy
  • Molecular targeted therapy
  • HER2 targeted therapy
  • Immunotherapy
  • Antibody drug conjugates
  • Clinical trials
  • Radiation therapy
  • Surgery

Research and Clinical Trials

The research conducted within our Breast Cancer Program encompasses a wide spectrum, ranging from preclinical investigations in the laboratory to clinical trials. Our primary objectives are to deepen our understanding of breast cancer biology and to pioneer innovative treatments for patients with this condition. Our dedicated team actively participates in clinical trials across all phases, including initial human trials for new drugs and drug combinations, as well as phase III randomized trials that can lead to the establishment of new standard-of-care therapies.

At Washington University, we are at the forefront of developing personalized treatment strategies for each patient facing breast cancer. We achieve this by harnessing tumor genomics, blood-based biomarkers, and cutting-edge imaging technologies. Our physician-scientists are also dedicated to exploring novel drugs that target the tumor microenvironment, with the goal of enhancing the effectiveness of immunotherapy and chemotherapy.
