The doctors, nurses, medical physicists, dosimetrists, and radiation therapists who provide your radiation in the UI Department of Radiation Oncology are professionals at the top of their field. Not only do they deliver this high level of care to hundreds of patients each year, they also are at the forefront of their discipline, pioneering new and more effective means to deliver your care safely and accurately.

Five Reasons Why Iowa Should Be Your Choice for Radiation Therapy

A Caring Team

Our doctors, nurses, and therapists are not only experts in cancer care, they're compassionate when it comes to your wellbeing. Our patients routinely give us the highest satisfaction scores for our service

A Multidisciplinary Approach

Our approach brings together specialists who focus on one or two types of cancer and who have expertise in chemotherapy, surgery, and radiation therapy. In one location, each member of the team comes together to see you rather than have you visit multiple clinics. 

Cancer Survivorship Clinic

Your care does not end when your treatment is over. Our cancer survivorship staff members help you cope with any side effects from the cancer and the cancer treatment.

Clinical Trials

Our own doctors partner with specialists around the country to offer new therapy techniques not yet available everywhere.

More Treatment Options

Our catalog of treatment types is comprehensive. Many hospitals offer one or two types of radiation therapy. At UI we offer many types of radiation therapy to best suit your specific needs. You have the confidence that we'll be using the treatment right for your condition.
