Our team

The Cheyenne Regional Cancer Center radiation oncology team is made up of board-certified radiation oncologists, board-certified medical physicists, a registered radiation therapist, certified medical dosimetrists and registered nurses who deliver quality, state-of-the-art care.

Types of treatment

Our radiation oncology team follows National Comprehensive Cancer Network Guidelines, recognized as the “standard of care” for cancer treatments.

At the Cheyenne Regional Cancer Center, we provide the following radiation oncology treatments:


Brachytherapy delivers radiation through catheters placed in the body. The patient is not considered “radioactive” since the radioactive source is removed after treatments.

External Beam Radiation Therapy (EBRT)

Machine-produced radiation is known as External Beam Radiation Therapy, or EBRT. The majority of radiation treatments provided at the Cheyenne Regional Cancer Center are EBRT.

A patient receiving conventional EBRT usually receives the treatment five days per week, Monday – Friday. A patient receiving EBRT is not radioactive after treatment, and no radiation is emitted when the machine stops.

Stereotactic Radio Surgery (SRS) and Stereotactic Body Radiation Therapy (SBRT)

Two forms of EBRT we provide at the Cheyenne Regional Cancer Center are Stereotactic Radio Surgery (SRS) and Stereotactic Body Radiation Therapy (SBRT). Compared to conventional EBRT treatments, SRS and SBRT usually require fewer treatments and higher doses/day. We often schedule SRS and SBRT so the body has time to recover after each treatment.

VitalBeam, the new linear accelerator, has several advancements, including an extremely narrow field of treatment to help ensure the preservation of surrounding tissue, short delivery times, high-resolution imaging and continuous accuracy checks.
