4,500 more cases: the NHS trust reopening a decade of breast cancer care

What happened
On Thursday 24 September 2026, the board of County Durham and Darlington NHS Foundation Trust held an extraordinary meeting in Durham. It agreed to widen an investigation into its own breast cancer service. The trust will now look back at around 4,500 more patient cases, going back to 2015. The work is expected to take about five years. Reviewers will work backwards one year at a time. This is an expansion of something already under way. The trust calls it a "look back exercise". So far it has reviewed 538 cases from January 2023 to February 2025. Of those, 321 involved some form of harm. In 77 cases the harm was significant. One patient is known to have died. The problems found include cancers that were missed, diagnoses that were delayed, and surgery that went further than it needed to. The trust believes 20 women had a mastectomy - the removal of a breast - that was not needed. At the meeting, interim chair Alison Marshall apologised. She said: "I would like to offer a sincere apology to all the women and their families who have been affected by the failings in our breast services." Chief nurse Gill Hunt told the board that concerns went back to 2015. That was when the service was reorganised and training posts for breast surgeons were lost. Separately, the National Crime Agency is working with Durham Police. They are assessing allegations from former patients and looking at whether any criminal offences may have been committed.
Why this matters
If you live in County Durham or Darlington, or you had breast care there, this is your hospital trust. That makes it personal, and worrying. But the story matters more widely than one corner of the North East, for three reasons. First, the scale. A look back over 4,500 cases is large even by NHS standards. The trust has already spent more than £500,000 on the review this year alone. That tells you how seriously it is being taken. Second, the type of harm. Breast cancer treatment decisions are life-changing and often permanent. You cannot undo a mastectomy. Being told, years later, that an operation might not have been needed is a particular kind of injury - and several women have spoken publicly about exactly that. Third, how long it took. Concerns are now traced back to 2015. Patients, the Northern Cancer Alliance, the Care Quality Commission and NHS England all raised worries over the years. The review is partly about why those warnings did not lead to change sooner. It is also worth saying plainly what this is not. This is one trust's breast surgery service, not the national NHS Breast Screening Programme. It is not a reason to skip a screening invitation or ignore a lump. Finding breast cancer early still gives people the best chance.
What the evidence actually says
It helps to be precise about the numbers, because they are easy to misread. The 321 harm findings come from 538 cases reviewed so far - not from the whole service, and not from the 4,500 cases still to be checked. That is a high proportion. But the cases reviewed first were chosen because they were the most recent, and the trust has not said the same rate will appear in older years. Nobody knows yet what the older cases will show. That is the whole point of extending the review. "Harm" also covers a wide range. At one end it means a delay or a conversation that should have happened and did not. At the other end it means a missed cancer, unnecessary surgery, or death. The 77 cases of significant harm, and the one death, sit at the serious end. An independent review of the trust's governance has already been published, along with the trust's own response. The trust accepted the findings and recommendations in full. In a joint statement, interim chair Alison Marshall and chief executive Steve Russell said the reports "highlight multiple missed opportunities, failures to act with curiosity, and a lack of the problem-sensing mindset needed to keep patients safe." The trust also says its breast service today is different from the one described in the reviews. Two new oncoplastic breast surgeons have joined. Decisions now go through an improved multidisciplinary team process, where specialists discuss a patient's care together. Leadership has changed, and the Care Quality Commission and NHS England are continuing to check progress. Those are the trust's own claims about itself. They are worth reading alongside the findings, not instead of them.
Qurexa perspective
We are a healthcare logistics and pharmacy delivery company in Lincolnshire. We have no connection to this trust and no part in this review, so we are not going to pretend otherwise. What we do see, regularly, is the knock-on effect of stories like this. When trust in a service is shaken, some people quietly step back from their own care. They put off a call. They stop a medicine because they are no longer sure it was the right one. They decide not to bother anyone. That reaction is understandable. It is also the thing most likely to cause you harm. If you are on medication after cancer treatment - hormone therapy such as tamoxifen or an aromatase inhibitor, for example - please keep taking it while you get answers. Stopping a prescribed medicine because you are worried about a different part of your care can create a new problem on top of the one you already have. Speak to your pharmacist or GP first. It costs nothing. Steady, reliable access to your medicines is genuinely the boring part of good care. It is also the part that keeps working while the big questions are being sorted out.
Practical advice
If you or someone close to you was treated by County Durham and Darlington NHS Foundation Trust: - The trust has a dedicated support line staffed by trained professionals. The number is 0191 333 2126 and the email address is [email protected]. More than 640 former patients had already used it before this week's decision, so you would not be the first or the odd one out. - You do not need to wait to be contacted. If your care is in the period being reviewed and you are anxious, you can ring and ask. - Keep your own records. Appointment letters, clinic letters, and dates are useful if you later want your case looked at. - You have the right to ask for your medical records. Your GP surgery or the trust can explain how. - If you want to make a claim, claims are handled by NHS Resolution, which is independent of the trust. You can approach them directly or use a solicitor. Citizens Advice, Action Against Medical Accidents (AvMA) and the Law Society can also point you to support. If you were treated anywhere else and this story has unsettled you: - Go to your screening appointment when you are invited. This review does not change that advice. - Get a new lump, change in shape, skin dimpling, or nipple change checked by your GP. Do not wait to see if it settles. - Ask questions about your own treatment. "Why this operation rather than a smaller one?" and "What are my other options?" are reasonable questions, and a good team will welcome them. - Ask for a second opinion if you want one. It is not rude, and it is not a complaint. - Keep taking prescribed medicines unless a clinician tells you to stop.
What to know
County Durham and Darlington NHS Foundation Trust has agreed to review around 4,500 more breast cancer cases, going back to 2015. Of 538 cases checked so far, 321 involved harm, 77 of them significant, and one patient died. The trust believes 20 women had mastectomies they did not need. The trust has apologised and accepted the review findings in full. Police and the National Crime Agency are assessing allegations separately. The review will take years. Answers for individual patients will not all arrive at once. In the meantime, the support line is open, your records are yours to ask for, and your own screening and treatment should carry on. If this story has worried you about your own care, the most useful next step is usually the simplest one: ring your GP surgery or speak to your pharmacist.
