Breast Density Notification: Current UK National Practice

Abstract

Increased breast density is a risk factor for breast cancer and can mask cancer on mammography. This survey attempts to understand clinician views regarding breast density notification in the United Kingdom. Two separate breast density surveys were distributed to radiologists and breast surgeons between May 2019 and May 2020. Invited participants were members of the British Society of Breast Radiology and the Association of Breast Surgeons. We received 232 completed questionnaires from 109 surgeons (71%) and 123 radiologists (41%). Fourteen percent of the surgeons reported discussing the increased risk of developing cancer with their patients, and 20% of the surgeons recommended further imaging compared with 50% of the radiologists. Fifty-two percent of surgeons and 28% of radiologists felt women should not be informed of their breast density scores considering the lack of National Health Service–funded supplementary imaging. Almost all respondents of this survey called for guidelines regarding the reporting and management of UK patients with increased breast density (90%). Density notification is becoming increasingly central to breast screening, and our results highlight an urgent need for a national consensus.
