    Our findings indicate that tomosynthesis e at least for the cur-rent version of the technology e does not improve the measure-ment of BC size relative to standard mammography, when cancers are seen on both tests. Tomosynthesis detects additional, mammographically-occult lesions in the screening setting, but measurement variability is large, and hence clinicians should be aware of the possibility of inaccurate measurement by tomosyn-thesis in those women. Given that the number of cancers detected only by tomosynthesis was modest, our finding of relatively inac-curate measurement in that group requires further exploration in larger studies, and should be interpreted in the context that tomosynthesis-only detection of BC was frequently in dense breasts  which also limits cancer size measurement.
