Behfar Ehdaie, MD, MPH, is a urologic surgeon at Memorial Sloan Kettering Cancer Center in New York City. He earned his medical degree at Georgetown University School of Medicine and then went on to a urology residency at the University of Virginia School of Medicine and a fellowship at Memorial Sloan Kettering Cancer Center. Dr. Ehdaie is an expert in minimally invasive surgical techniques for the treatment of urologic cancers, and has a particular interest in novel management of prostate cancer, kidney tumors, and bladder cancer. He has performed more than 500 MRI-guided prostate biopsies and is experienced in doing extensive lymph node removals at the time of prostate surgery. His research is focused on achieving prostate cancer cures while also preserving quality of life, and he is currently the principal investigator on a clinical trial of partial gland ablation that theoretically could allow patients with prostate cancer to receive effective treatment minus side effects like incontinence and erectile dysfunction. Dr. Ehdaie also aims to improve active surveillance by developing a large surveillance clinic that will use advanced imaging and biomarkers to detect cancer progression. Dr. Ehdaie has given presentations on prostate cancer throughout the United States and around the world, and has also published numerous articles and studies in peer-reviewed journals.
