New contrast mammography could spot breast cancer recurrence earlier
NCT ID NCT06105749
First seen Jun 25, 2026 · Last updated Aug 20, 2026 · Updated 3 times
Summary
This study is testing whether adding a special type of mammogram (contrast-enhanced mammography, or CEM) every two years to the standard yearly 3D mammogram can find new breast cancers in women who have already had breast cancer. The goal is to see if CEM detects more cancers while keeping false alarms low. About 1,500 women aged 30-79 who are at least one year past their breast cancer treatment will participate.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- contrast-enhanced mammography (CEM)
- What this could lead to
- If successful, this could lead to a more accurate screening method for women who have had breast cancer, catching new cancers earlier with fewer false alarms.
- What could go wrong
- This is a single-arm study without a control group, so results may not prove superiority over standard screening. Also, CEM requires an IV contrast injection, which carries a small risk of allergic reaction.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Asymptomatic women, ages 30-79, with a personal history of breast cancer who are at least one year out from any breast cancer surgery and/or treatment and are scheduled to have a routine annual mammogram with tomosynthesis (DBT). Exclusion Criteria: * Women with a history of prior moderate or severe iodinated contrast reaction \[only those with a prior mild reaction that can be managed by pre-medication AND with and a strong desire to participate will be allowed to participate. However, among these women with a mild sensitivity, if they are allergic to Benadryl (one of the premedications), they will be excluded\]. * Women with implant(s) in the breasts to be screened (as this creates artifacts and diagnostic performance of imaging in women with implants likely does not generalize to those without implants, and the sample size with implants would be too small to infer conclusions. * Women who have had bilateral mastectomy * Women with a history of kidney failure or estimated glomerular filtration rate (eGFR) \< 30 mL/min * Pregnancy or lactation * Women actively being treated for cancer of any type with chemotherapy. * Women with stage 4 metastasis to visceral areas or brain * Women with known personal history of breast cancer who have a screening breast MRI exam within 24 months prior to the current round of CEM. * Women with known personal history of breast cancer who had a CEM exam within the prior 23 months
