Hospital leaders in County Durham have agreed to review as many as 4,500 more breast cancer cases after uncovering serious failings, including delayed diagnoses and unnecessary surgeries. The review will extend to cases going back to 2015, significantly broadening the scope beyond the initial examination of cases from January 2023 to February 2025.
The audit, part of the County Durham and Darlington NHS Foundation Trust, was prompted by concerns raised since 2015 about breast cancer treatment that was not aligned with best clinical practices. These concerns surfaced after a reconfiguration of services and the loss of breast surgical trainee positions, according to the trust’s chief nurse, Gill Hunt.
Extent of Harm and Initial Findings
Since April 2025, the review focused on 538 cases within the two-year period, revealing that 321 patients experienced some form of harm, including one death. Approximately 640 patients have reached out to a special helpline requesting their cases be assessed, highlighting widespread distress and uncertainty among those affected.
The failings reported include delayed cancer diagnoses and excessive surgical interventions, such as unnecessary mastectomies. One patient reportedly felt “mutilated” and described the trust’s mistakes as “absolutely unforgivable.”
Trust Leadership Apologies and Commitments
At an extraordinary meeting of the trust’s board held in Durham, board chair Alison Marshall issued a “sincere apology” to all women affected by the failings in breast services, acknowledging the profound impact on patients and their families. Senior officials emphasized openness and transparency, committing to a clinical review governed by evidence and clear rationale.
Chief executive Steve Russell expressed awareness of the distress caused, saying no apology can erase the harm but assuring ongoing support for affected patients. Women who underwent unnecessary mastectomies may now be offered breast reconstruction surgeries that they rightfully should have received initially. Russell also noted that the trust currently surpasses national standards for breast cancer treatment, including higher rates of breast conserving surgeries and immediate reconstructions.
Next Steps and Ongoing Support
The board agreed to extend the lookback review one year at a time toward 2015, a process estimated to take up to five years and cover thousands of additional cases. The helpline remains open for any patient seeking review irrespective of when they were treated.
The trust highlights that these ongoing efforts aim to learn from past mistakes, improve patient responses to concerns, and ensure future treatments meet appropriate clinical standards. Patients today can expect care aligned with best practices, with the trust striving to prevent recurrence of past errors.
