Radiation therapy for colorectal cancer

Your doctor may offer radiation therapy as a colorectal cancer treatment option for a number of reasons, including: 

  • Radiation therapy delivered before surgery may help shrink tumors so they are easier to remove.
  • Radiation therapy given after surgery may help kill cancer cells that have been left behind.
  • The treatment may be an option for patients who are unable to undergo surgery.
  • Radiation therapy may be used as palliative treatment, to help shrink tumors that may be causing a blockage in the colon or intestines.
  • Radiation therapy may be given in conjunction with chemotherapy.
