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.

Pretty good: Usually they're part of a protocol. If I were offered this as adjuvant Rx and it was affordable from my end, I'd probably go ahead if it was offered by an ethical oncologist. I'd quit if it was clearly not helping.
