First seen Feb 26, 2026 · Last updated May 06, 2026 · Updated 7 times

Summary

This study tests whether taking a medication called ulipristal acetate before a mammogram can temporarily reduce breast density in premenopausal women with extremely dense breasts. Dense tissue can hide cancers on mammograms, so lowering density might improve detection. About 26 participants will have their mammograms compared before and after taking the drug to see if breast density decreases.
