Margie Petersen Breast Center

Providence Saint John's Health Center

With an emphasis on patient dignity and comfort, the Margie Petersen Breast Center at Providence Saint John’s Health Center offers some of the finest breast care in Southern California.  We want to change the way women look at breast health, and can identify and treat breast issues from pain and discharge to cancer.

For those diagnosed with breast cancer, we focus on caring for the whole person: mind, body and spirit and provide access to medical expertise, innovative treatments and support services.

Personalized care

Our doctors and nurse navigator make sure to provide each patient, and their families, a comprehensive and personalized path to the most effective treatment. This includes combining quality care with integrated practices such as mindfulness and yoga. From the moment you walk through our doors, you can expect to find compassion and a tranquil environment.

Using evidence-based medical and surgical treatments, our healthcare professionals strive to provide the best outcomes. Our range of services for patients includes:

  • Advanced breast imaging including tomosynthesis (3-D mammography)
  • Innovative surgical and non-surgical treatments
  • Sentinel node biopsy and targeted radiation
  • Intraoperative radiation therapy (IORT)
  • Oncoplastic breast surgery
  • Access to clinical trials and research
  • Genetic risk assessments and prevention, especially for BRCA1 and 2 gene mutations
  • Nutritional counseling
  • Integrative therapies including yoga and meditation

Already a leader in breast cancer treatment, the Margie Petersen Breast Center at Providence Saint John’s Health Center also offers a cancer prevention program to shift the focus to prevention of breast cancer, especially in those with hereditary risk.

Assessing genetic and hereditary cancer risk

Cancer risk assessment, genetic testing and education are available at the Margie Petersen Breast Center, which employs a full time board-certified physician who is a specialist in clinical cancer genetics, risk assessment and prevention. Our cancer geneticist is able to test for all of the hereditary cancer syndromes with available tests–such as the BRCA mutation test–although nearly 25 different genes are involved in cancer syndromes. Through the Cancer Prevention Program, patients can be assessed for a variety of cancers and testing is not limited to breast cancer alone.

Cancer care tailored for you

At Providence Saint John’s, we believe that treatment is only half of the story and that prevention is the other half. This program is a natural step in our goal of advocating for personalized care by thoroughly assessing individual risk based on both personal and family history, and of providing education and resources to reduce that risk.
