Apr 8, 2021 WEDNESDAY, April 7, 2021 (HealthDay News) — Women undergoing screening with digital breast tomosynthesis (DBT) have a lower interval cancer rate compared with those screened with digital mammography (DM) alone, according to a study published online April 6 in Radiology. Kristin Johnson, M.D., from Skåne University Hospital in Malmö, Sweden, and colleagues compared interval cancer rates and tumor characteristics in DBT screening to those in a population screened with DM. Data were included for 14,848 women screened with DBT and DM in the prospective population-based Malmö Breast Tomosynthesis Screening Trial (MBTST) between January 2010 and February 2015. A total of 13,369 women in the trial were compared to a matched control group of 26,738 women of the same age and screening occasion screened with DM at the same center.
