Study Summary

This randomized phase III trial studies digital tomosynthesis mammography and digital mammography in screening patients for breast cancer. Screening for breast cancer with tomosynthesis mammography may be superior to digital mammography for breast cancer screening and may help reduce the need for additional imaging or treatment.

Primary Outcome

The cumulative proportions of participants experiencing the primary endpoint in the two study arms will be compared. The primary comparison of the two study arms will be approached from an Intent-to-Treat perspective and will be based on a two-sided test for comparing binomial proportions.
