Changes to This Summary (10/10/2016)

The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.

Breast Cancer Screening Imaging Modalities

Added text to state that a study designed to address the limitation of previous studies by using a large database and digital mammography in women aged 40 to 89 years found no evidence that computer-aided detection (CAD) improves screening mammography performance for four outcomes: sensitivity, specificity, screen-detected cancers, and detection of interval cancers; in this study, CAD did detect higher rates of ductal carcinoma in situ (cited Lehman et al. as reference 20).

Harms of Screening

Added text to state that based on statistical models, the risk would be doubled in women with large breast who require increased radiation doses and in women with breast augmentation who require additional views; radiation-induced breast cancers may be reduced fivefold for women who begin biennial screening at age 50 years rather than annually at age 40 years (cited Miglioretti et al. as reference 35).

This summary is written and maintained by the PDQ Screening and Prevention Editorial Board, which is editorially independent of NCI.
