Official title
Progesterone Receptor Modulator Mammogram Pretreatment for Premenopausal People With a History of Dense Breast Tissue
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This phase II trial tests whether taking ulipristal acetate prior to a mammogram decreases breast density for people with a history of dense breast tissue. One limitation to breast cancer screening with mammography is dense breast tissue, which decreases the sensitivity of screening as breast density masks cancer and precancerous lesions. Ulipristal acetate lowers the amount of progesterone made by the body which may temporarily decrease the density of the breast tissue, allowing for a more accurate mammogram for people with dense breast tissue.
