Our Mission

To Heal. To Teach. To Discover. University Hospitals’ mission echoes throughout UH Seidman Cancer Center and the Department of Radiation Oncology.

What Makes Us Different?

We are proud to be the only center in Cleveland and among only a few centers worldwide to offer stereotactic radiosurgery, stereotactic body radiotherapy, intra-operative radiotherapy, low-dose, and high-dose-rate brachytherapy, total skin electron therapy, total body radiotherapy, proton beam therapy, and radiopharmaceutical therapy with radium-223 and Lutetium-177 PSMA. Less than 5% of the centers worldwide offer this comprehensive array of radiation treatment options. These technologies represent a sizable investment to ensure our patients have access to the latest technologies. However, this is only half of the equation to receiving a successful course of radiation therapy. Comprised of experts in planning and delivering radiotherapy, we require exquisite precision from our incredible radiation therapists, dosimetrists, and medical physicists.

Innovative Research & Clinical Trials

We are here for the patient. UH Seidman Cancer Center’s Department of Radiation Oncology has also pioneered numerous cutting-edge technologies and treatments through our dedication to the design and conduct of clinical trials.

While excellence lives within the Department of Radiation Oncology, we recognize that the patient's journey goes beyond our doors. Thus, we are proud to work as part of incredible multi-disciplinary teams to make this journey as seamless and exceptional as possible.


We are dedicated to working with you and your staff to refer a patient or schedule a consultation.

Medical Education

Our residency programs train the next generation of radiation oncology physicians and medical physicists.
