Study Population Description
Pre-menopausal and Post-menopausal aged 45-74 scheduled for, or have intent to schedule, a screening mammogram.
The purpose of the EA1151 (TMIST) trial is to determine whether screening for breast cancer with a newer technology called tomosynthesis mammography- TM (3-D) is more effective compared to the standard digital mammography- DM (2-D) in detecting early and aggressive breast cancers in women 45 to 74 years old.

Inclusion Criteria
  • Patients must be scheduled for, or have intent to schedule, a screening mammogram

  • Patients must be willing and able to provide a written informed consent
  • Breast density will be determined by prior mammography reports, when available. All other risk factors used to determine patient eligibility for annual or biennial screening will be determined by subject self-report
  • Please contact study personnel for more eligibility criteria
Exclusion Criteria
  • Women of childbearing potential must not be known to be pregnant or lactating
