Optimal Mammography View Sequencing in Women With a History of Breast Cancer Undergoing Surveillance Mammography

This prospective, single-centre, parallel-group randomised controlled trial evaluates the optimal sequencing of mammography views in women with a history of breast cancer undergoing surveillance mammography. Women treated with breast-conserving surgery within the previous five years will be randomised 1:1:1:1 to one of four mammography view sequencing groups. The primary objective is to compare patient-reported pain and satisfaction across sequencing groups. Secondary objectives include comparison of image quality (PGMI scoring), compression force, and breast thickness. A total of 400 participants will be enrolled at Beaumont Hospital Breast Care Centre over 2.5 years.
