Context: Types of treatment for childhood cancer
Radiation therapy uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. Colorectal cancer may be treated with external beam radiation therapy. This type of radiation therapy uses a machine outside the body to send radiation toward the area of the body with cancer. Radiation therapy may be given alone or with other treatments, such as chemotherapy.
