Peter Hyung-Kyun Ahn, MD| Radiation Oncology | MedStar Health
About me
Peter H. Ahn, MD, director of the Head and Neck Cancer Radiation Oncology program, joined the medical staff of MedStar Georgetown University Hospital's Department of Radiation Medicine in 2017, after five years as a radiation oncologist and assistant professor with the University of Pennsylvania Health System.
Fellowship-trained at MD Anderson Cancer Center and board-certified in Radiation Oncology, Dr. Ahn has extensive experience in treating cancers of the head and neck, skin (including melanoma), skull base, and brain using a variety of therapeutic approaches, including conventional and proton beam radiation therapies. He is nationally recognized by Castle Connolly's annual publication, "America's Top Doctors."
Dr. Ahn's research has been funded by industry, private and public sources including NIH, and been published in peer-reviewed journals. A frequent guest lecturer and presenter, he is also a reviewer for multiple scientific and medical publications.
Philosophy of Care
"No two cancer patients are exactly alike, so the need and ability to highly customize radiation treatment requires disease-specific training and extensive experience. Minimizing the long-term side-effects of today's advanced treatments is also a major consideration. Dealing with the unique challenges inherent in each patient's social situation, individual goals of care, and tumor characteristics keeps me excited about my work as a member of the dedicated and experienced team of physicians, nurses, technicians and physicists at MedStar Georgetown."
