Evidence-based breast cancer screening guidelines for women who received chest irradiation at a young age.

Follow-upguidelinesareimportantforthelong-termhealthcare of cancer survivors, particularly those treated at a young age. Appropriate guidelines are powerful tools to improve quality of care, reduce variability in clinical practice, and contain cost. Instituting clear and evidence-based standards is essential for compliance of both patients and providers. Hence, it is encouraging that guidelines on routine imaging of cancer survivors for early detection of treatment-related breastcancer(BC)arefinallysupportedbydirectevidenceforefficacy.
