What is radiation therapy treatment for colon cancer?

Hmmm: Most colon cancers are treated with surgery and possibly chemotherapy. Rectal cancers are treated with a combination of surgery and possibly chemo and radiation therapy. Very rare to treat colon cancer with radiation therapy.

Energy beams: For certain types of colorectal cancer, energy beams are focused in the cancerous area. These beams are designed to kill cancer cells and decrease the chance of the tumor growing back. Depending on the situation, radiation can be used either before an operation or after an operation.
