TMIST Mammography Study (Breast Cancer Screening)

We are doing this study to compare two different screening mammography methods in pre- and post-menopausal women to understand whether one method is better than the other at finding life-threatening breast cancers.

Breast Cancer Detection

Women ages 45-74

If you choose to join this study, you will get a random assignement (like the flip of a coin) to screening with Tomosynthesis Mammography (TM) or Digital Mammography (DM) .

The frequency and number of screening mammograms will vary with your menopausal status and whether you have breast cancer risk factors.

• All premenopausal women will have annual screening
• Postmenopausal women will have screening every 2 years unless they have any specific risk factors
• All participants will be followed for 4.5 to 8 years
