Radiation Therapy

Radiation therapy is one of the most common and important methods of cancer treatment and is used in about half of all cancer cases. It works by delivering high doses of radiation with special equipment to target cancerous tumors, killing or damaging 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)

State-of-the-art linear accelerators (LINACs) are used at CCSO to deliver external beam radiation therapy, which include 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.

High dose rate brachytherapy treatments are delivered with a Nucletron multi-channel remote afterloader with a Ir-192 source. Gynecological, accelerated partial breast irradiation (APBI), and brachytherapy breast boost treatments are delivered with the remote afterloader and the Accuboost treatment system.

Multi-modality treatments are offered 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.
