Is it possible to get radiation therapy for colon cancer?

Yes.: Current treatment of rectal cancer that extends into the wall of the rectum or involves adjacent lymph nodes is preoperative radiation and chemotherapy followed by surgery. Furthermore, cancers of the colon that have directly invaded adjacent organs or the abdominal wall are treated with radiation therapy after surgery.

Yes: Radiation is standard treatment for rectal cancers which have not spread and is used in combination with chemotherapy. For pure colon cancers, radiation is used sometimes in special situations (e.g. Cancer involving nearby critical organ or causing pain/ bleeding). The main therapies for colon cancer though are surgery and chemotherapy.
