Radiation Therapy

Radiation therapy is one of the most common and important methods of cancer treatment. Therefore, about half of all cancer cases involve radiation therapy. It works by delivering high doses of radiation with special equipment to target cancerous tumors. It kills or damages them so they can’t grow, multiply, and/or spread.

Radiation therapy services at Cancer Centers of Southwest Oklahoma include:

  • Three-dimensional conformal radiation therapy
  • Intensity modulated radiation therapy (IMRT)
  • Image-guided radiation therapy (IGRT)
  • Electron beam therapy
  • Brachytherapy (High dose rate)

We use State-of-the-art linear accelerators (LINACs) at CCSO to deliver external beam radiation therapy. This includes three-dimensional conformal therapy, electron beam therapy, intensity modulated radiation therapy (IMRT), and image guided radiation therapy (IGRT). IGRT ensures that radiation is delivered with great accuracy by using imaging during treatment to enhance patient positioning and alignment.

A Nucletron multi-channel remote afterloader delivers high dose rate brachytherapy treatments with a Ir-192 source. The remote afterloader and the Accuboost treatment system deliver the gynecological, accelerated partial breast irradiation (APBI), and brachytherapy breast boost treatments.

We also offer multi-modality treatments for certain cancers. For example, brachytherapy may be combined with external beam radiotherapy (EBRT) to improve the overall effectiveness and limit the side effects from the radiation dose.

Volumetric-Modulated Arc Therapy (VMAT)

VMAT is a faster way to treat patients that need IMRT treatments, often cutting the treatment times in half. Another benefit is VMAT’s ability to deliver a more conformal dose to the cancer tissue.
