This case reports on secondary extramedullary multiple myeloma within both breasts in the absence of axillary nodal involvement and discusses the difficulty in interpretation with clinical recommendations and learning outcomes. Differentiating plasmacytic lesions in the breast is often difficult as clinical and radiological appearances are known to mimic benignity and high-grade primary breast cancer. Extramedullary presentation can determine progression of the disease and can necessitate cross-sectional imaging. Therefore definitive diagnosis is essential as the clinical management of the patient may be altered.

The JBBA has an outstandingly streamlined submissions process, the reviewers comments have been constructive and valuable, and it is outstandingly well produced, presented and promulgated. It is in my opinion the leading journal for blockchain research and I expect it to maintain that distinction under the direction of its forward-looking leadership team.

Objective: The study aims to explore the perceptions of Advanced Practice Radiographers (APRs) currently giving benign biopsy results to extend their role to deliver NHS Breast Screening Programme (NHSBSP) malignant outcomes. In the UK, APRs are appropriately trained to deliver results, yet traditionally have been cultured not to. Increasing pressures on NHSBSP units are a key driver for APR evolvement. A significant lack of published research provides the rationale for the study, combined with an identified service need. Methods: Following ethical approval, a grounded theory design was applied to interview six APRs individually in a single breast screening unit. Extracted themes were considered during a subsequent focus group. Results: Five core themes identified; (i) role of the APR, (ii) patient experience, (iii) efficiency, (iv) role boundaries, and (v) delivering results. The findings indicate the ambiguity of radiographers delivering results within their profession, outlining the potential impact on themselves and patients. Mammography APRs are skilled to deliver results, and whilst enforced barriers may restrict extension a supportive environment can overcome these. Additional training is necessary to implement the role in the screening service. Conclusion: Identified within their scope of practice; APRs have the ability with appropriate training and peer support to effectively deliver results with a patient-centred approach. Advances in knowledge: This study has identified important enabling factors and challenges concerning role extension in the delivery of breast biopsy results. The apparent suitability of APRs to communicate results may address breast service pressures, with benefit to patients and the radiology profession.
