New mammogram technique could spot breast cancer earlier in survivors
NCT ID NCT04085510
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether contrast-enhanced mammography (CEM) finds breast cancer more accurately than standard mammography in women who have already had breast cancer. About 1,647 women ages 30-85 will get both types of mammograms to compare detection rates and false alarms. The goal is to improve surveillance without unnecessary extra tests.

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 30-85, with a personal history of breast cancer who have had at least one routine mammogram since treatment. Exclusion Criteria: * Women with a history of prior iodinated contrast reaction * 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 * Lump or other breast symptoms * Abnormality on prior breast imaging that is being followed.
