Hospital chiefs at the County Durham and Darlington NHS Foundation Trust have agreed to expand an ongoing breast services lookback review by up to an additional 4,500 cases. The decision follows identified failings that included delayed diagnoses and excessive surgeries.
Board Votes to Expand Inquiry to 2015
This widened inquiry comes directly on the heels of an initial review launched in April 2025. That investigation covered cases between January 2023 and February 2025, revealing that hundreds of patients experienced harm. According to reporting by the BBC and the Irish Independent, the findings included one death and twenty unnecessary breast removals.
Extraordinary Meeting in Durham Triggers Broader Look
The decision to widen the scope of the investigation came during an extraordinary meeting of the trust’s board held in Durham. Board members voted to examine cases dating back to 2015.
Trust chair Alison Marshall offered a sincere apology to all affected women and their families. She acknowledged that while the board cannot turn back the clock, leadership remains committed to operating with complete transparency regarding the failings, as reported by the BBC.
Origins of the Crisis Trace Back a Decade
Chief nurse Gill Hunt informed the board that concerns originated in 2015. The trouble began following a service reconfiguration and the subsequent loss of breast surgical trainee posts.

Over the years, regulatory bodies and healthcare organizations raised multiple issues. These watchdogs included the Care Quality Commission, NHS England, and the Northern Cancer Alliance.
Hundreds Suffer Harm in Initial Evaluation Phase
Out of 538 cases evaluated thus far in the initial review phase covering 2023 to 2025, investigators found that 321 patients suffered some form of harm, including one fatality.
Multiple affected individuals spoke with the BBC. One patient described the outcome of her treatment as feeling mutilated, characterizing the trust’s errors as entirely unforgivable.
Core Themes Reveal Systemic Failings
Chief nurse Gill Hunt noted the core themes identified across the reviewed cases. The data showed treatment that failed to align with best practice, excessive surgery, and delayed diagnoses.
