Best order of mammogram views after breast-conserving surgery
Official title: Optimal Mammography View Sequencing in Women With a History of Breast Cancer Undergoing Surveillance Mammography
Run by Royal College of Surgeons, Ireland · NCT07443579 · Data updated 2026-11-12
This test sees if the order in which mammogram views are taken affects pain and satisfaction for women who had breast-conserving surgery within the past five years.

Is this trial a fit for you?
✓Likely a good fit
Women aged 18 or older who had breast-conserving surgery (wide local excision) and radiotherapy within the past five years and are attending their first annual surveillance mammogram after treatment are ideal candidates.
✕Probably not a fit
Patients with a prior mastectomy, bilateral wide local excision, men, those more than five years post-treatment, or those unable to give informed consent are unlikely to benefit from this protocol.

What this trial studies
This single-centre, randomized, parallel-group trial assigns 400 women 1:1:1:1 to one of four mammography view sequences during their first annual surveillance mammogram after breast-conserving surgery and radiotherapy. Pain is measured with a visual analogue scale before and after the exam and patient satisfaction is recorded with a post-procedure questionnaire as the primary outcomes. Secondary outcomes include blinded retrospective image quality scoring using PGMI by two radiologists, recorded compression force, and breast thickness. The study uses an intention-to-treat analysis and is conducted at the Beaumont RCSI Cancer Centre over approximately 2.5 years.
Why it matters
Potential benefit: If successful, changing the order of views could reduce discomfort during mammography and improve patient satisfaction while maintaining image quality.
How similar studies have gone: There is limited prior research on view sequencing and its effects on pain or image quality, so this approach is relatively untested.
