Not All Breast Doctors are Created Equal. Here’s How to Find the Right Doctor for You
Finding the right breast care doctor is important. In fact, it may be one of the most important health decisions you can make. But not all breast care doctors are created equal. In this blog post, we explore the different types of doctors and the advantages of seeing a fellowship-trained breast doctor for your care.
Your Safety is Our Top Priority!

We are scheduling appointments for breast imaging and in-person visits. We want to assure you that we have implemented a response plan that allows us to focus on our top priority: delivering excellent care while protecting the health and safety of our patients, visitors and staff.

Quick Appointments & Results
Finding a breast lump can be unsettling for both women and men, alike. Fortunately, most mammographic calcifications and painful breast lumps are not cancer, which is why we offer the peace of mind that comes with quickly securing an appointment.Schedule an Appointment
The Latest Clinical Trials and Research
Clinical trials help doctors and scientists find better ways to diagnose, treat, and prevent disease. Individuals who volunteer for clinical trials play an active role in their own health care and help others by advancing medicine. Our doctors make clinical trials a regular part of cancer care to increase overall cancer survival and expedite the development of a cure. At the Saint John’s Cancer Institute you can participate in studies led by internationally renowned researchers. If you are interested in a clinical trial, please speak with your provider.
In the early 1990’s the leaders of the Saint John’s Cancer Institute raised the idea of creating a center dedicated to the treatment and research of breast cancer. An extraordinary gift from Joyce Eisenberg Keefer, a dedicated champion for cancer research and treatment, allowed them to bring their vision to fruition and, in 1993, they opened the multidisciplinary breast center at Saint John’s Health Center. Unfortunately, the building that housed the breast center was damaged beyond repair in the 1994 Northridge earthquake. Once again a generous philanthropist, Margie Petersen, stepped in to provide the financial support necessary to rebuild the breast center.Learn More
Thank you Dr. Grumley for accepting me as a patient at the Margie Petersen Breast Cancer Center. I am forever blessed and grateful to have been referred to you. Your breast cancer specialty has given me quality of life. Thank you for your gentleness, kindness, and caring spirit. My family and I thank you from the bottom of our hearts.
I went to see Dr. Fischer about a breast cancer returning. He had returned from a breast cancer conference a week before and shared some recent insight about my cancer. He has a wonderful bedside manner and is respectful and patient.
I am now days away from chemo #2 of 8 and I want to thank Dr. Grumley, my incredible breast surgeon. I was fearful at every step, but I trusted Dr. Grumley and her team. She saved my life!
Dr. Fischer is always available by cell and stayed in constant contact throughout the winter holidays. He and his team are true professionals and I highly recommend him.
I have been coming to the Margie Petersen Breast Center for years for my mammograms and I have never encountered anything except great service by competent and knowledgeable staff. Everyone is always warm and friendly.
