Receiving a diagnosis of cancer can be frightening and confusing. To help you and your family better understand the treatment options available to you, the American Society for Therapeutic Radiology and Oncology has created this Web site to explain how radiation therapy is used to safely and effectively treat cancer.

The information on this site was created by physicians and other members of the radiation oncology team with expertise on the topic presented. However, this material is informational only and should not be used in place of advice from a medical professional. If you have questions about a specific treatment, please ask your radiation oncologist.
