Types of Treatment

Radiation oncology is a form of cancer treatment that uses radiation from a machine-produced source or a radioactive source. Below are the kinds of radiation oncology treatments provided at the Cheyenne Regional Cancer Center.:

External Beam Radiation Therapy

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.

SRS and SBRT Treatments

One form of EBRT provided at the Cheyenne Regional Cancer Center is known as stereotactic radio surgery, or SRS. Another form of EBRT provided at the Cancer Center is known as stereotactic body radiation therapy, or SBRT. SRS and SBRT usually require fewer treatments and higher doses/day than conventional EBRT treatments do. SRS and SBRT are often scheduled so that the body has time to recover after each treatment.


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