About me

Miriam Jacobs, MD, is board-certified and fellowship-trained in medical oncology at MedStar Georgetown Cancer Institute at MedStar Georgetown University Hospital. As a specialist in early and advanced breast cancers, Dr. Jacobs provides chemotherapy, hormone therapy, immunotherapy, precision medicine, and clinical trials. She is also a member of the American Association of Cancer Research, the American Society of Hematology, and the American Society of Clinical Oncology. 

Dr. Jacobs’ approach to care focuses on providing individualized and holistic treatments. She begins by talking with patients to learn about their medical histories and health goals. She then collaborates with an experienced team of radiation oncologists and surgeons to develop comprehensive and tailored wellness plans. She also educates patients about natural, traditional, and state-of-the-art cancer treatments.

Dr. Jacobs is dedicated to advancing the field of precision medicine – an innovative form of care that uses people’s own cells to develop highly personalized prevention, diagnosis, and treatment options. She is particularly interested in providing hormone receptor-positive, CAR T-cell, and CAR NK-cell therapies to improve the health of breast cancer survivors. Referring physicians should know that she is available to give second opinions and discuss clinical trial opportunities.

Philosophy of care

“Research creates endless possibilities to discover new methods of treating complex diseases or enhancing people’s lives. As a clinical researcher, I’m passionate about contributing to the collection of knowledge that can lead to immediate medical solutions or future health innovations. I’m also grateful to clinical trial participants who are true healthcare pioneers and heroes.”

    This was my initial appointment with this doctor. I felt like my needs and questions were not answered and she didn't care. So hopefully my insurance covers another hospital!

  • Jan 16, 2025

    Very kind & helpful. Super knowledgeable. Took the time to explain everything. Very personable.

  • Dec 27, 2024

    Doctor was not prepared for the appointment. Did not listen to me nor did she seemed to be prepared for an actual discussion. She seemed to just want me to agree with her plan she crafted on the spot.
