Breast Cancer Misdiagnosis And Unnecessary Breast Surgery Claims

When breast cancer is missed, diagnosed late or wrongly identified, patients may face delayed treatment, avoidable pain and unnecessary anxiety. In some cases, errors in diagnosis, imaging, pathology or clinical decision-making can also lead to unnecessary breast surgery, including procedures that should never have taken place.

At Hugh James, our specialist medical negligence solicitors support clients affected by breast cancer misdiagnosis and unnecessary breast surgery. We understand the physical and emotional impact these errors can have, and we are committed to helping people find answers, secure accountability and pursue compensation where negligent care has caused avoidable harm.

If you have suffered because of a missed breast cancer diagnosis, delayed diagnosis, false positive diagnosis or unnecessary breast surgery, our team can advise you on whether you may be able to bring a claim.

Are breast cancer diagnosis rates improving and why are errors still happening?

The picture across the UK is mixed:

Screening and early detection are improving. NHS England reported that in 2024/25, 1.94 million women attended screening within six months of invitation (a 10-year high), and 19,291 cancers were detected through NHS breast screening — nearly 16% more than the previous year.
These improvements are supported by national reporting and datasets tracking screening invites, uptake and outcomes.
However, improved detection does not eliminate risk. Even with strong national screening programmes, patients can still experience missed findings, incorrect interpretation of tests, failures to escalate symptoms, or avoidable surgical decisions which are the types of issues now under scrutiny in the North East investigation.

The system is detecting more cancers earlier but individual patients can still be failed by poor assessment, communication, decision-making, or governance.

Examples of breast cancer-related clinical negligence

We regularly support people affected by:

Missed or delayed diagnosis (including a failure to investigate symptoms, misread imaging, or delayed referral)
Misdiagnosis leading to unnecessary surgery (including avoidable mastectomy or avoidable lumpectomy)
Surgical errors and poor outcomes (including avoidable scarring, asymmetry, infection, and tissue damage)
Reconstruction concerns (including incorrect implant selection/placement, avoidable complications, or poor follow-up care)
Failures in aftercare (including poor wound management, failure to act on post-operative concerns, or delays in corrective treatment)

Client case studies: common themes we see

While every case is different, common themes include communication failures, poor decision-making, inadequate consent discussions, and missed opportunities to reassess or seek a second opinion.

The case of one of our clients delay in diagnosis of breast cancer displays this clearly. X received over £200,000 in compensation, with the help of Partner, Lesley Herbertson, and Solicitor, Kelly Charlton, within the Clinical Negligence team at Hugh James, after medical professionals failed to diagnose her breast cancer promptly, despite ongoing symptoms, leading to more invasive treatment that could likely have been avoided with earlier investigation.

Signs you may have been misdiagnosed or mistreated

People often contact us because they feel something was “not quite right”, for example:

you were reassured despite persistent symptoms
your test results were unclear, but no further steps were taken
your diagnosis changed significantly after surgery or after a second opinion
you were not given clear options (or felt pressured into one option)
you later learned that information was missed or not acted upon

If you are worried, it’s also helpful to check reliable symptom guidance and speak to a clinician. The NHS sets out what to look for and when to seek medical advice.

What to do if you think your breast cancer care was wrong

1) Get medical advice promptly

If you have ongoing symptoms or new concerns, contact your GP or breast care team. For screening-related queries, the NHS also advises contacting your GP surgery (which should receive a copy of results) or your local breast screening service.

2) Ask questions and request information

You can ask the provider for copies of relevant records (such as clinic letters, imaging reports, pathology reports and consent forms). This can help you understand what happened and when.

3) Consider raising a formal complaint

Making a complaint can:

help you get answers
prompt an internal review
ensure concerns are recorded properly

Cancer Research UK provides a clear overview of how to complain about NHS or private healthcare and who can help.

4) Speak to a specialist clinical negligence solicitor

A legal review can help establish:

whether the care fell below an acceptable standard, and
whether that failure caused avoidable harm (physical, psychological, or financial)

How we can help

Our clinical negligence team can:

listen to what happened and what you’ve been told since
identify the key questions your records should answer
obtain independent expert evidence where appropriate
advise you clearly on prospects, funding options and next steps

FAQs

If you are concerned that your breast cancer was diagnosed late, misdiagnosed or not treated appropriately, one of the first steps is to obtain your medical records.

In most cases, you should ask for records from every healthcare provider involved in your care. This may include:

your GP records including referral letters
hospital notes including breast clinic records and surgical records
NHS Breast Screening Programme records
mammograms, ultrasound scans, MRI scans and imaging reports
biopsy and pathology results
oncology and radiotherapy records
discharge summaries
any complaint correspondence or hospital investigation reports

It is often helpful to ask for the scans and images themselves, not just the written reports.

These records can usually be requested by making a Subject Access Request. If you are unsure what to ask for, our medical negligence team can help identify which records may be relevant to your case and help you obtain them.

You may have a breast cancer negligence claim if your medical care fell below an acceptable standard and this caused you avoidable harm.

Examples may include:

a delay in referring you for further investigation
a failure to act on breast symptoms or abnormal test results
a missed or delayed diagnosis
a delay in starting treatment
incorrect advice or inadequate follow-up care

To bring a successful claim, it is not enough to show that there was a mistake. You also need to show that the mistake made a difference to your outcome. For example, that an earlier diagnosis or earlier treatment would probably have led to a better prognosis, less extensive treatment or a reduced risk of the cancer progressing.

Our specialist solicitors can review your circumstances, obtain your records and arrange independent expert evidence to advise you on whether you may have a claim.

In most cases, you have three years to start a medical negligence claim.

This time limit usually runs from the date of the negligent treatment, or from the date you first became aware that your injury may have been caused by substandard care.

There are exceptions to this rule. Different time limits may apply if:

the claim is for a child
the injured person lacks mental capacity
the claim is being brought after a loved one has died

Time limits in medical negligence cases can be complex, so it is important to seek legal advice as soon as possible. Even if you are unsure whether you are within time, we may still be able to advise you.

Yes, in some circumstances a family member can bring a claim on behalf of someone else.

This may happen where:

the person affected is a child
the person affected does not have the mental capacity to manage their own claim
the person has died

If someone lacks capacity, a family member or other suitable person may be able to act for them in the claim.

If a loved one has died, certain claims may be brought by their estate or by eligible dependants, depending on the circumstances.

If you are contacting us on behalf of a relative, we can advise you on whether you are able to pursue a claim and what steps need to be taken.
