The Radiation Oncology Clinic at the University of Colorado Cancer Center is a multidisciplinary cancer treatment program acknowledged as one of the best in the United States.

We specialize in minimally invasive radiation treatments, such as:

  • stereotactic radiosurgery
  • brachytherapy
  • biologic-based radiotherapy
  • intensity modulated radiation therapy
  • stereotactic body radiation therapy
  • TomoTherapy® Hi-Art® treatment system (find out more about this advanced technology)
  • Gamma Knife therapy

Each of these treatments protects your normal tissue from high doses of radiation while targeting the tumor or cancer. Find out more.

Specialists who really specialize

Unlike other hospitals that have general radiation oncologists, our radiation oncologists specialize in certain cancers. This means that your radiation oncologist has extensive experience in your particular kind of cancer—and more experience often leads to better outcomes.

Moreover, many of our specialists serve on the national committees that set the standards of care - and they bring that deep expertise to their patients at UCH.

Your radiation oncologist at the CU Cancer Center will work in tandem with all of your cancer doctors to make sure you are receiving appropriate care. He or she will attend weekly meetings to discuss your case and make sure you are on track, and keep your primary care physician briefed about your care and progress.

Why Choose the CU Cancer Center for Your Cancer Radiation Therapy?

  • National leaders. Our radiation oncologists are nationally renowned for radiation therapy treatment and research, serving as leaders in the Radiation Therapy Oncology Group and other national, research-based organizations that actually set the standards of care.
  • Colorado's only dedicated pediatric radiation oncologist. In conjunction with Children’s Hospital Colorado, we feature the only dedicated pediatric radiation oncologist in the state.
