David J. Byun, MD

At Perlmutter Cancer Center and NYC Health + Hospitals/Bellevue, I use the most advanced imaging and interventional strategies to provide radiation therapy to patients diagnosed with genitourinary cancer, or cancer of the urinary tract and male reproductive system. While I find intellectual fulfillment from the technical aspects of my work, what truly fuels me is forming profound connections with my patients. Helping people navigate treatment and its challenges is not just a responsibility—it is an honor.

I am an advocate for patient empowerment. I want you as my patient to fully understand the purpose of a consultation, the role of radiotherapy in your overall treatment plan, and what to expect throughout your radiotherapy journey. My goal is to ensure you feel engaged and equipped to weigh the benefits of the therapy against possible side effects.

In addition, I collaborate with electrophysiologists at NYU Langone’s Heart Rhythm Center to offer a revolutionary form of noninvasive cardiac ablative therapy that uses precise stereotactic radiation techniques. We use this innovative approach to treat ventricular tachycardia, or rapid heart rhythm in the lower heart chambers, that does not respond to conventional medical and catheter-based ablative therapies.

When not caring for patients, I serve on the editorial board of JCO Clinic Cancer Informatics and spearhead grant-supported research in prostate cancer, stereotactic cardiac radioablation, and digital health innovation. My early contributions to the field have been recognized with several awards, including the Radiation Oncology Institute Personalized Radiation Therapy Research Award and the Radiological Society of North America Roentgen Resident/Fellow Research Award.

Thank you for allowing me to be part of your care team.
