About me

About the Provider
Christopher Gallagher, MD, is Medical Director of Cancer Services of the Washington Cancer Institute and teaching attending physician at the MedStar Washington Hospital Center. Prior to joining the Hospital Center, Dr. Gallagher served as Chief of Hematology-Oncology Service for Walter Reed National Military Medical Center, was the Fellowship Program Director for the National Capital Consortium Hematology-Oncology Fellowship Program, and the Deputy Director of the John P. Murtha Cancer Center at the Walter Reed National Military Medical Center.

As an expert in breast medical oncology, Dr. Gallagher specializes in the diagnosis and treatment of breast cancer through the use of hormone therapy, chemotherapy, and immunotherapy. His clinical interests include the treatment of advanced or metastatic disease through the use of novel therapeutic treatments.

Dr. Gallagher received his medical degree from Georgetown University School of Medicine, where he graduated with honors and was inducted into the Alpha Omega Alpha (AOA) Honor Medical Society. He then joined the Walter Reed Army Medical Center where he completed a residency in internal medicine, and a fellowship in hematology/oncology.

The Washington Cancer Institute offers a comprehensive portfolio of clinical trials that provides novel therapeutic medications for individuals diagnosed with early stage and advanced breast cancer. Dr. Gallagher's research interests include investigating and understanding disparities in outcomes. He is especially interested in enrolling minority groups, such as African-Americans and Latinos, in research trials that are often excluded from larger clinical trials.

Dr. Gallagher is an advocate for the advancement of immunotherapy, or the use of the patient's own immune system in order to treat breast cancer, as well as targeted therapy derived from the genetic sequencing of breast tumors in order to detect abnormalities that may indicate a response from a specific drug. He is widely published and has been invited to speak nationally on numerous occasions regarding his research within the breast cancer field.

Philosophy of Care
"Conversation is the foundation of my practice. My role as a breast medical oncologist is to educate my patients and their family members on the available treatment options for their specific type of breast cancer. I take the time to listen to my patients, to answer their questions, and to address their concerns. By educating my patients, I involve them in their care and empower them in making informed decisions. It is important to me that my patients understand their disease, their treatment, and the big picture of their diagnosis."

"I advocate for my patients. Each day, I take the time to appreciate my mission - taking care of women with breast cancer."
