Radiation Therapy for Colon Cancer

Radiation therapy uses high-powered X-rays, seeds or radioactive material to shrink or destroy your tumor.
Image Guidance Makes Targeting Tumors More

At Scott & White, we use Image-Guided Radiation Therapy (IGRT) during the course of our radiation oncology treatments in areas of the body that are prone to movement. IGRT is the use of frequent imaging during your radiation therapy treatment to ensure absolute accuracy of treatment.

Benefits of IGRT include:

  • Patient and tumor motion tracked with the use of image guidance
  • Radiation beam adjusted in response to current tumor image to maintain accuracy and reduce likelihood of harming nearby tissue
  • Helps target tumors to sub-millimeter accuracy
  • Features computerized robotic delivery and stereotactic localization imaging
  • Requires an imaging series, which is transferred to computer, before treatment begins
  • Used in conjunction with IMRT, 3DCRT and stereotactic radiotherapy

For more information, see Image-Guided Radiation Therapy on RadiologyInfo.org.

Abdominal Compression Further Increases Accuracy

At Scott & White, radiation therapy for colon cancer may include the use of an abdominal compression device for areas of the body that are prone to movement. This helps ensure you're properly positioned during treatment, thereby increasing its effectiveness.

What we are doing right now with radiation therapy is changing the paradigm of cancer care with all the newer evidence-based research and practice of medicine. We’re offering a bigger chance of cure for every single patient when they come in the doors of Scott & White for any of the GI cancers, as opposed to what it would have been 5 or 10 years ago.

How Radiation Therapy Is Used to Treat Cancer

Radiation therapy is infrequently used to treat colon cancer. However, in some cases, your physician may recommend radiation therapy for your cancer of the colon.

Radiation therapy is used in some cases:

  • For patients who are not good candidates for surgery
  • In conjunction with chemotherapy
  • For cancer that returns after surgery
