Summary: You may have a medical negligence claim in Ireland if a delay in diagnosing your oesophageal or stomach cancer followed warning signs a competent doctor should have acted on. The two most common failures are persistent reflux treated as ordinary heartburn, and difficulty swallowing left without an urgent endoscopy.

This page applies the cancer misdiagnosis principles in our main guide to these two upper gastrointestinal cancers. This is general information, not legal advice. Every case depends on its specific facts. Consult a solicitor about your situation.

How oesophageal and stomach cancer is misdiagnosed or diagnosed late

In brief: these cancers are most often missed in two ways. Persistent reflux or indigestion gets treated as harmless. Or difficulty swallowing isn't sent for the urgent endoscopy that alarm symptoms call for.

Oesophageal and gastric cancers are difficult to catch early because their first symptoms look ordinary. Persistent heartburn, acid reflux, indigestion, a feeling of food sticking, early fullness at meals, and unexplained weight loss all overlap with common, harmless complaints. That overlap creates a real risk of diagnostic anchoring, where a doctor settles on reflux or an ulcer and doesn't keep looking. A previous label such as irritable bowel syndrome can make a later cancer harder to spot, because new symptoms get filed under the old diagnosis.

The numbers explain why timing matters so much. Around 520 people are diagnosed with oesophageal cancer in Ireland each year. Irish Cancer Society / NCRI (Updated 2024) [1] About 570 are diagnosed with stomach cancer. Irish Cancer Society / NCRI (Updated 2024) [2] Ireland and the UK report among the highest rates of oesophageal adenocarcinoma in the world, and five-year survival sits at roughly 24%. Trinity College Dublin / NCRI (Updated 2023) [3] When the cancer is found while it's still localised, survival is far higher than when it has spread. A delay that lets it advance therefore carries a heavy cost.

Irish guidance sets a clear standard for when these symptoms should be investigated. Under the HSE Endoscopy Programme triage guidance, a patient with dyspepsia or reflux plus an alarm symptom, such as difficulty swallowing, weight loss, or anaemia, should be referred for urgent review and upper gastrointestinal endoscopy within four weeks. Severe, sudden difficulty swallowing should be treated as an emergency. HSE Endoscopy Programme triage guidance (Updated 2024) [4] Sometimes a GP keeps prescribing antacids or proton pump inhibitors for months while red-flag symptoms persist. If that urgent referral never starts, that's where a late diagnosis claim begins to form.

The pattern of repeated visits is well documented. In a systematic review, 29% of people with oesophageal cancer and 36% of those with gastric cancer had three or more primary care consultations before they were diagnosed. Around 22% of oesophageal and 33% of gastric cancers were picked up only after an emergency presentation. British Journal of General Practice meta-analysis (Updated 2015) [5] Several visits for the same persistent symptoms, with no endoscopy referral, is exactly the record an expert later examines.

Common ways the diagnosis is missed

In brief: failures happen at the GP referral stage, at endoscopy, in the laboratory, and in hospital systems that lose track of abnormal results.

A late diagnosis is rarely just one mistake. It's usually a chain of missed opportunities, and finding where the chain broke is central to proving the claim.

• Failure to refer on red-flag symptoms. Persistent dysphagia, unexplained weight loss, or iron-deficiency anaemia without an obvious cause should trigger urgent investigation. Treating these as simple reflux, an ulcer, or "stress" without an endoscopy is a measurable departure from the standard of care. It's the kind of gap an expert can point to.
• Delayed or downgraded endoscopy. A referral marked routine rather than urgent can add months to the wait. The triage decision itself can be a breach if the symptoms met the urgent criteria. The HSE target is that no patient waits more than four weeks for an urgent endoscopy. HIQA (Updated 2024) [6] Reality often falls short. At the end of 2025, 34,595 people in Ireland were waiting for a GI endoscopy. NTPF figures, reported by The Irish Times (Updated January 2026) [7] A claim still turns on the specific failure in your case, such as a downgraded or late referral, rather than the backlog alone.
• Missed Barrett's oesophagus surveillance. Barrett's oesophagus is the only known precursor to oesophageal adenocarcinoma, and it is meant to be monitored by regular endoscopy. The danger is that early cancer often develops silently in patients whose reflux feels well controlled on medication. That's exactly why surveillance exists. NICE Barrett's guidance, peer-reviewed summary (Updated 2024) [8]
• Endoscopy and biopsy interpretation errors. A visual look isn't enough on its own. One prospective study found that diagnosing Barrett's oesophagus on endoscopic appearance alone, without waiting for the tissue result, was wrong in 42.9% of cases when checked against histopathology. Diagnostic accuracy study, PMC (Updated 2020) [9] Failing to wait for, or correctly read, the biopsy report is a recognised point of failure.
• Systems failures. An abnormal scan or biopsy that is filed without recall, or an incidental finding nobody follows up, can let a treatable cancer grow unchecked. See our guidance on test results not followed up.

The strongest evidence of breach is often a missed or downgraded referral rather than the missed diagnosis itself. The GP's own notes record the symptoms you presented with. If those symptoms matched the urgent criteria and the referral wasn't urgent, that gap speaks for itself. For the wider duty, see our guide to failure to refer for urgent investigation.

Signs your diagnosis may have been negligently delayed

In brief: repeated visits for the same upper-GI symptoms with no endoscopy, difficulty swallowing that was never referred urgently, or a "normal" endoscopy shortly before a cancer diagnosis are all signs worth checking.

None of these proves negligence on its own, but each is a pattern an expert would look at closely. If one or more of these matches your experience, it may be worth having your records reviewed.

• You saw your GP three or more times for the same persistent reflux, indigestion, or swallowing trouble, and no endoscopy was arranged.
• You had difficulty swallowing (dysphagia) at any age and were not referred for an urgent endoscopy.
• You were 55 or older with weight loss plus reflux, indigestion, or upper abdominal pain, and the urgent cancer pathway was not used.
• An endoscopy or scan was reported as normal, and you were diagnosed with cancer a short time later.
• A biopsy showed Barrett's oesophagus or abnormal cells, and no follow-up or surveillance was arranged.
• Iron-deficiency anaemia with no obvious cause was treated with supplements but never investigated.

Doctors should weigh red-flag symptoms against the national referral standard. The table below sets out the symptom, the action expected under the National Cancer Control Programme criteria, and where the breach typically lies.

Proving negligence: breach of duty and causation

In brief: you must show two things. First, the care fell below the Dunne standard. Second, the delay caused a distinct injury, usually a shift to a higher cancer stage with worse survival.

Two things have to be proven. The first is breach of duty. Irish law uses the Dunne principles, not the English Bolam test. The question is whether no competent practitioner of equal standing, acting with ordinary care, would have made the same error. Applied here, the plaintiff must show that no reasonable GP would have left persistent dysphagia or alarm symptoms without an urgent endoscopy referral. The full standard and how it interacts with clinical guidelines is set out on our cancer misdiagnosis hub.

The second is causation, and that's usually where these cases are won or lost. It isn't enough that a diagnosis was late. You must show the delay caused a measurable injury beyond the underlying disease. In cancer claims that injury is typically a stage shift, the worsening of cancer stage between when it should have been found and when it actually was. An independent upper gastrointestinal or oncology expert reconstructs the timeline from your endoscopy dates, histology grade, and staging scans. They then quantify the difference in prognosis and treatment. Our page on causation in medical negligence explains how this proof is built.

Being realistic matters here. A delay of a few weeks rarely changes the stage, so a short delay on its own is often not enough. The claims that succeed usually involve months of missed red-flag symptoms, where the cancer moved from one stage to a worse one during the delay. The question an expert answers is simple to state and hard to prove: at the stage it should have been caught, what treatment and survival would you have had, and what did the delay cost you?

Defence teams know this, so they'll often accept that a delay happened while fighting causation. Some stomach cancers are aggressive. Diffuse-type and signet ring cell tumours spread early and have no clear precursor. With these, the defence may argue the outcome would have been the same regardless. That makes expert evidence on tumour behaviour and stage progression essential, and it is why these claims usually need more than one expert report.

Loss of chance: did the delay reduce your survival or treatment options?

In brief: Irish law can compensate the loss of a real chance of better treatment or longer survival, even where the original odds were already poor.

Many people are told their cancer was advanced and assume that rules out a claim. It often doesn't. Irish courts recognise loss of chance, the loss of a genuine opportunity for a better outcome, even where the chance of full recovery was below 50%. The principle is explained on our loss of chance page.

This matters for oesophageal and gastric cancer because the curative window is narrow and the survival drop between stages is steep. The diagram and table below show indicative five-year survival for oesophageal cancer by how far it has spread. Rates vary by tumour biology and treatment and are illustrative only.

The legal injury is that difference. When negligence lets a localised, curable cancer advance to regional or distant disease, the cost is real. The patient loses curative surgery, faces more gruelling treatment, and loses years of life expectancy. Loss of chance lets the law put a value on that lost opportunity even where survival was never certain.

Compensation: what a claim may include

In brief: a claim has two money parts. General damages cover pain, suffering, and reduced life expectancy, assessed under the Personal Injuries Guidelines (ceiling about €550,000). Uncapped special damages cover financial losses such as care and lost earnings.

Compensation in Irish clinical negligence falls into two parts. General damages cover pain, suffering, and the loss of a normal life, including reduced life expectancy. These are assessed by reference to the Personal Injuries Guidelines (Updated 2021) [12], where the ceiling for the most catastrophic injuries is about €550,000. A proposed 16.7% increase to roughly €642,000 was not brought to a vote in 2025, so the 2021 figure still applies. Cancer misdiagnosis does not have its own tariff line, so the court weighs your age, the reduction in life expectancy, and the nature and duration of treatment. Our guide to general damages in medical negligence and our overview of how Irish damages are assessed explain the brackets. Any figure here is illustrative, and outcomes vary case by case.

Special damages cover quantifiable financial loss and are not capped. They can include past and future loss of earnings, the cost of private treatment, and travel to appointments. They also cover future care needs, such as specialist dietary support after surgery to the oesophagus or stomach. In serious cases these losses far outweigh the general damages figure. Our guides to what you can claim for and general versus special damages set out the categories.

Where a late diagnosis has been fatal, a separate claim is available to the family under Part IV of the Civil Liability Act 1961. A single action is brought for all statutory dependants. It can include loss of financial dependency and the value of lost services. It also includes a fixed statutory payment for mental distress, the solatium. That payment's capped in total at €35,000 and divided among the dependants. Civil Liability Act 1961, Irish Statute Book (Updated 1961) [13]

To give a sense of scale, Irish delayed-cancer-diagnosis claims have resolved at significant levels. Reported settlements include one of around €3.5 million where a GP delayed a cancer referral by several months, and a €600,000 settlement reached at mediation in a missed-screening colorectal cancer case. These are other people's cases with different facts, not a prediction for yours, and clinical negligence damages are assessed differently from the Personal Injuries Guidelines tariff. We track Irish outcomes on our page covering recent medical negligence cases in Ireland.

Time limits and date of knowledge

In brief: you generally have two years to start a claim. The clock runs from your date of knowledge, which is often later than the missed appointment.

The limitation period for a clinical negligence claim is two years (reduced from three by s.7 of the Civil Liability and Courts Act 2004, which amended the Statute of Limitations (Amendment) Act 1991). The important point for late cancer diagnosis is when that clock starts. Under the 1991 Act, time runs from your date of knowledge. That's the date you first knew, or ought reasonably to have known, that you had a significant injury and that it was caused by a healthcare provider's act or omission. Statute of Limitations (Amendment) Act 1991, s.2 (Updated 1991) [14]

In practice this often helps patients. Say an endoscopy in one year was wrongly reported as clear. You only learn of the error years later, when symptoms return and a scan reveals advanced cancer. The two years generally runs from that later discovery, not the original report. Because gathering hospital records and an independent expert report takes months, it is wise to seek advice early. Different rules apply for children and for people who lack capacity. Our date of knowledge page explains how this is applied.

How we can help
