Unnecessary NHS Mastectomy Review
NHS Trust Review Finds Twenty Women Underwent Unnecessary Mastectomies Due to Failures

Key Points
1
The trust’s review included 640 former patients who contacted a dedicated helpline, in addition to the 539 cases formally assessed.
2
The harm assessment also recorded 242 cases of minor harm, beyond the cases classified as moderate or severe harm and the reported death.
3
Rachel Gray’s independent review found that therapeutic mammoplasty—removing the cancer while reshaping the breast—could have been offered instead of a mastectomy; she said she was never presented with another option and later had to wear a fake breast.
4
A Royal College of Surgeons report found little evidence that the trust’s breast unit contributed adequately to multidisciplinary team meetings, meaning major treatment decisions could be based on individual surgeons’ unchallenged opinions.
5
Patient Catriona Dunbar said the trust’s apology contained no acknowledgment of who was responsible, arguing that “accountability is what we need here” and that nobody was taking ownership of the harm caused.
County Durham and Darlington NHS Foundation Trust found that 20 women underwent mastectomies that were not clinically necessary, according to ITV. A review of 539 cases between January 2023 and February 2025 also identified 59 cases of moderate harm, 19 cases of severe harm, and one patient death. The trust is now expanding its review to cover approximately 4,500 cases dating back to 2015 after investigators uncovered failures in decision-making processes and outdated surgical practices.
Patients Denied Alternatives to Mastectomy
Women at the trust were not offered less-invasive surgical options despite them being clinically appropriate. Patient Rachel Gray learned through an independent review that therapeutic mammoplasty—which removes cancer while reshaping the breast—could have replaced her mastectomy. ITV reported that Gray said she was never presented with alternative options and later had to wear a fake breast. Another patient, Denise Howarth, similarly stated she was wrongly told mastectomy was necessary without being offered breast-conserving surgery or immediate reconstruction.
Systemic Failures in Medical Review Processes
A Royal College of Surgeons report identified that the trust's breast unit failed to adequately participate in multidisciplinary team meetings, where major treatment decisions should be made collectively. This meant individual surgeons' opinions went unchallenged, leading to non-standard care. According to ITV, the external investigation also raised concerns about financial incentives linked to outsourced procedures that may have influenced clinical decisions. Beyond the 539 formally assessed cases, 640 former patients contacted a dedicated helpline seeking answers about their care.
Scale of Harm Extends Across Hundreds of Cases
The harm review documented far more than just the 20 unnecessary mastectomies. KMFM reported that the assessment recorded 242 cases of minor harm in addition to the moderate, severe, and fatal cases. Among the 539 cases reviewed, 20 also involved delayed diagnoses that could have affected treatment outcomes. The decision to expand the review to 4,500 cases suggests the scope of problems may be significantly larger than initially identified.
Patients Call for Clear Accountability
Patient advocates argue that the trust's apology lacks meaningful accountability. Catriona Dunbar stated that the trust's response contained no acknowledgment of who was responsible for the failures. Hello Rayo reported that campaigners emphasized "accountability is what we need here" and that nobody was taking ownership of the harm caused. With the review now expanding to cover over a decade of cases, patient groups are pushing for a formal public inquiry into the trust's breast cancer services.
