False positives in breast cancer screening with one-view breast tomosynthesis: An analysis of findings leading to recall, work-up and biopsy rates in the Malmö Breast Tomosynthesis Screening Trial.

• Tomosynthesis screening gave a higher false-positive recall rate than mammography • There was a decline in the false-positive recall rate for tomosynthesis • The recall due to stellate distortions simulating malignancy was doubled with tomosynthesis • Tomosynthesis found more radial and postoperative scar tissue than mammography • Tomosynthesis is better at characterising rounded lesions.
