Radiation Oncology

Widest range of treatment options

Many patients diagnosed with cancer will receive radiation treatment, or radiotherapy, during the course of their treatment plan. Based upon your unique cancer diagnosis, your radiation oncologist will recommend the best treatment available for your type and stage of cancer.

Patient story

Daran Wankum is just 18 years old and battling brain cancer at The University of Kansas Cancer Center. A tool helping Daran wage his war is the TrueBeam Accelerator. The technology helps radiation oncologists pinpoint and attack Daran's tumor while protecting the surrounding brain tissue.

Radiation treatment options

  • Brachytherapy
    Brachytherapy treatment uses ionizing radiation delivered by radioactive material that is placed a short distance from, or within, the tumor. For example, prostate cancer brachytherapy involves the insertion of radioactive seeds into the prostate gland using ultrasound-and-template-guided technology. Brachytherapy is also used to treat breast, cervical, uterine and vaginal cancers. Depending on the type of cancer you have, we deliver high-dose rate or low-dose rate brachytherapy.
  • Calypso localization system
    Referred to as “GPS for the body,” the Calypso system pinpoints a tumor’s exact location, allowing real-time tracking during prostate cancer treatment. As a result, during each treatment session, radiation can be delivered accurately and precisely, with limited radiation exposure to surrounding tissues and organs. The Calypso system’s ability to track prostate movement minimizes the risk of under-dosing the tumor, reduces the exposure of healthy tissue to additional radiation and decreases serious side effects.
  • Intensity-modulated radiation therapy and image-guided radiation therapy
    Intensity-modulated radiation therapy (IMRT) and image-guided radiation therapy (IGRT) uses varied strengths of radiation beams that are targeted with a 3D approach. They deliver high doses of radiation that conform to the shape of the tumor while minimizing radiation to the surrounding organs. IMRT allows very high doses of radiation to be delivered to multiple tumor types, such as prostate, head and neck, lung and brain, with minimal side effects. IGRT uses imaging technology, such as CT scanning, to deliver IMRT.
  • Stereotactic radiosurgery and radiotherapy
    Stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT) target tumors in the brain, spine, lung and liver. For patients who can’t be treated with surgery, SRS offers an effective noninvasive option with similar outcomes. It may also be combined with surgery to treat any remaining cancerous cells. SRS directs a single fraction of a high dose of tightly focused radiation beams onto the tumor while minimizing the radiation dose to the surrounding normal tissues or organs. As a result, it reduces long-term side effects. When delivered using from 2-5 fractions, SRS is called stereotactic radiotherapy or SRT.
