§ PUBLISHED JUDGMENTS

Real cancer misdiagnosis & delayed diagnosis cases, decided by the courts.

Every case below is a published judgment of the courts of England and Wales, linked to its source. Summaries are ours; amounts appear only where the judgment states them. We include claims that failed, because they show what has to be proved.

Claimant succeeded£550,000

Alexander v HCA International Limited & Anor

[2026] EWHC 1284 (KB)·2026·Liability decided at trial

A patient developed life-threatening pancreatitis after a gallstone-removal ERCP. The judge found the consultant never prescribed or instructed the standard preventive diclofenac suppository, so it was not given, and entered judgment for £550,000 against him.

Failing to give a recognised prophylactic drug before a procedure can be negligent even in private care. The prescribing doctor, not the hospital, carried the liability here.

Claimant succeeded

Wilma Agnes Cullen v Dr Ruth Henniker-Major

[2024] EWHC 2809 (KB)·2024·Damages assessed at trial

A GP saw Ms Cullen three times over five weeks with a persistent cough, sore throat and tiredness but did not make an urgent cancer referral; her laryngeal cancer was diagnosed at stage III about three months later. Liability was admitted, and the trial dealt with disputed care costs and the defendant's allegation that she had been fundamentally dishonest, which the judge rejected.

A delayed cancer referral claim turns on what extra treatment the delay caused; here the admitted delay meant chemotherapy, a total laryngectomy and neck dissections that earlier diagnosis would have avoided. Social media posts relied on to allege dishonesty were found not to contradict her evidence.

Claimant succeeded

Cripps v Norfolk and Norwich University Hospitals NHS Foundation Trust

[2024] EWHC 615 (KB)·2024·Damages assessed at trial

The trust admitted that a misreported smear delayed the diagnosis of cervical cancer, and the claimant, who lost her fertility through treatment, asked for a further interim payment to fund surrogacy abroad. The judge refused because the evidence was not yet complete enough to be confident a trial judge would allow that cost.

Even with liability admitted, an interim payment will only be ordered for sums the court is confident will be recovered at trial. Whether overseas surrogacy costs are recoverable depends on a reasonableness test decided on full evidence.

Claimant succeeded

Shaw v Maguire

[2023] EWHC 2155 (KB)·2023·Liability decided at trial

A skin sample taken in 2007 was reported as benign but in fact showed melanoma, which was only picked up in 2009 and caused the patient's death in 2014. His widow issued proceedings over five years late after her first solicitors let the case drift, and the court allowed the claim to proceed.

The clock can start later than the mistake itself, because it only runs once you know the injury is serious. Delay caused by former solicitors rather than by the claimant is far less likely to defeat a late claim, especially where the original slides and reports survive.

Claim failed

O'Brien v Guy's & St Thomas' NHS Trust

[2022] EWHC 2735 (KB)·2022·Liability decided at trial

A man with end-stage kidney failure was given a single 400mg gentamicin dose for a chest infection and suffered permanent balance and hearing damage. His sister's claim failed because the judge accepted that a high dose was a reasonable choice for a worsening infection with sepsis risk, despite his renal impairment.

A drug dose that causes known side-effects is not automatically negligent if it was a reasonable clinical judgement in the circumstances. Departing from a hospital guideline is not itself proof of negligence.

Claimant succeeded

Plan v El-Amir & Anor

[2020] EWHC 2902 (QB)·2020·Liability decided at trial

A 79-year-old with macular degeneration was persuaded to have an intraocular lens implant in her better eye without proper informed consent, then developed raised eye pressure that the surgeon left untreated for five weeks. Stacey J found the surgeon negligent both in consenting and in delaying laser treatment, causing total blindness in that eye.

Private eye surgeons must obtain genuinely informed consent and act promptly on post-operative complications. A delay that materially contributes to permanent damage is enough for liability even if some harm had already occurred.

About Cancer Misdiagnosis & Delayed Diagnosis Claims

Cancer claims usually concern delay: symptoms or abnormal test results that should have triggered urgent investigation were dismissed, misread or not followed up, and by the time the cancer was diagnosed it had advanced — requiring more aggressive treatment or reducing the prospects of cure. The most common failing is a GP not referring a patient with red-flag symptoms, but delays also occur in screening programmes, radiology reporting and hospital follow-up.

NICE guidance (NG12) sets out the urgent suspected cancer referral pathway — previously known as the "two-week wait": patients whose symptoms raise a suspicion of cancer — for example rectal bleeding, a persistent lump, unexplained weight loss, post-menopausal bleeding or a persistent change in bowel habit — should be referred urgently, and under the NHS Faster Diagnosis Standard (which replaced the two-week wait in England in October 2023) cancer should be confirmed or ruled out within 28 days of referral. For care before October 2023, the two-week wait was the applicable standard. A failure to refer when the guidance clearly called for it, or a failure to act on an abnormal scan, smear or blood result, can be strong evidence of negligence.

The critical legal question is usually causation: what difference did the delay make? Expert oncology evidence compares the likely stage, treatment and prognosis at the time diagnosis should have happened with the position when it actually happened. A delay that changed curative treatment into palliative care, or required mastectomy or stoma surgery that earlier diagnosis would have avoided, founds a substantial claim.

Compensation typically ranges from £30,000 where the delay caused additional treatment and avoidable suffering, to £250,000–£1.5 million where it caused a materially worse prognosis, more radical surgery or reduced life expectancy. Where the patient has died, the family can claim under the Fatal Accidents Act 1976. The limitation period is generally 3 years from the date of knowledge of the delay.
