Radiation Oncology Center

Methodist's Radiation Oncology Center offers the full range of radiation therapy options, including external beam radiation, such as Stereotactic Body Radiosurgery, IMRT, and others. Our caring team of specialized physicians and experienced clinical staff work to improve outcomes and ensure your experience is as comfortable and pain-free as possible. 

Stereotactic Body Radiosurgery

Stereotactic Body Radiosurgery is not a surgery, but a revolutionary alternative to surgery. Methodist Hospitals has had great success using this approach to treat medically inoperable lung cancer, lung metastasis, and liver metastasis.

This completely non-invasive procedure employs exacting pinpoint radiation directed at the cancer using multiple, precisely contoured beams delivered from many different angles. It is so precise, larger doses of radiation can be delivered over a shorter period of time, sparing normal and healthy tissue.

The potency of doses reduces treatment time to three days as compared to the typical eight-week course of radiation therapy. Stereotactic Body Radiosurgery can be used to support other cancer treatment therapies or in cases where surgery, standard radiation and chemotherapy are either not options or were ineffective. Some patients choose this option to avoid the side effects of chemotherapy or standard radiation.

Benefits of Stereotactic Body Radiosurgery:
  • 3-day treatment time
  • No hospitalization required
  • Completely non-invasive
  • Alternative to conventional surgery
  • Spares healthy tissue
  • Appropriate for treating lung cancer, lung metastasis and liver metastasis
Applications of Stereotactic Body Radiosurgery include:
Medically Inoperable Lung Cancer

Patients who are unable to tolerate lung cancer surgery due to factors such as advanced age, poor lung function, poor heart function or generally poor medical condition are ideal candidates for Stereotactic Body Radiosurgery.

Lung Metastasis

Sometimes cancerous tumors spread, or metastasize, from the primary site to the lung. Tumors can spread from breast cancer, lung cancer, colon cancer, prostate cancer, and others. Stereotactic Body Radiosurgery is a highly effective alternative to conventional surgery or chemotherapy with minimal side effects to the patient.

Liver Metastasis

Cancerous tumors can spread, or metastasize, from the primary site to the liver. These cancers can include breast cancer, lung cancer, colon cancer, prostate cancer, and others. Stereotactic Body Radiosurgery is a highly effective alternative to conventional surgery or chemotherapy for eliminating these tumors.

Intensity Modulated Radiation Therapy (IMRT)

One of the most significant breakthroughs in radiation treatments of the last three decades, IMRT can reach hard-to-access tumors with laser accuracy. In IMRT, advanced computer programming allows clinicians to shape the beam around the tumor, avoiding surrounding tissue. Such increased precision can enable physicians to considerably increase the dose directed to a malignant tumor, thus increasing the opportunity of complete tumor elimination.

Methodist Hospitals uses the latest Varian linear accelerators, combined with electronic portal imaging systems to plan a three-dimensional, precise dose of radiation. IMRT therapy is frequently used in conjunction with other therapies.

Advantages of IMRT
  • Treats hard-to-reach tumors with pinpoint accuracy
  • Heightened accuracy enables use of higher radiation doses
  • Precision delivery spares more healthy tissue


HDR cancer therapy attacks malignant tumors by placing a radioactive source within or around cancerous tissue. Our expert radiation oncologists ensure the maximum radiation dose is given where it is most needed, preventing most of the radiation from reaching the surrounding healthy tissue. Most often administered on an outpatient basis, HDR can decrease the number of actual treatments needed.

Accelerated Partial Breast and Whole Breast Radiation

Accelerated Partial Breast Irradiation - APBI - is a targeted technique that delivers radiation to the lumpectomy cavity and a small area of surrounding tissue. APBI allows a higher dose of radiation to be delivered thereby decreasing the overall treatments to approximately 5 days.

External Beam Radiation Therapy - EBRT - is a method for delivering high doses of radiation to destroy cancer cells and shrink tumors. Methodist uses a large machine called a Varian 2100 EX linear accelerator to deliver EBRT.

Gamma Knife

Not a knife at all, the Gamma Knife  is a unique, sophisticated technology that allows brain surgery to be performed without a scalpel. Learn more about the uses and benefits of the Gamma Knife.
