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.

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.

How effective is radiation therapy for treating colon cancer?

Partially effective: The best approach for colon cancer is resection. If lesion is large such as one in the rectosigmoid, then RT plus chemo can be employed to reduce the lesion for resection. While the end effect minimizes local recurrence, it does not alter overall survival.

Surgery+/-ChemoRx: The cornerstone of therapy is surgical resection of the part of the colon. The stage of the cancer is dependent upon the surgical findings (depth of cancer, lymph node evaluation), which will guide the decision regarding chemotherapy. Very rarely, radiation therapy will be recommended for more advanced colon cancers.
