Our team of radiation oncologists, dosimetrists, physicists, therapists, and nurses are all specially trained to treat specific cancers and we work side-by-side with other Johns Hopkins experts, including surgical oncology, medical oncology, pathology, and interventional radiology to create individualized treatment plans for each patient, using targeted technologies including Proton Therapy and procedures such as Brachytherapy. Our patient safety program - cited as one of the best in the nation - employs quality assurance protocols and innovative techniques to ensure the safety and well-being of all of our patients.
