By Mayo Clinic staffIf you're receiving radiation to a tumor, your doctor may have you undergo periodic scans after your treatment to see how your cancer has responded to radiation therapy. In some cases your cancer may respond to treatment right away. In other cases it may take weeks or months for your cancer to respond. Some people aren't helped by radiation therapy.
