What You Need to Know To Maximise Compensation for Gastric Cancer Claims

Gastric cancer negligence claims result from a poor standard of medical care which led to further harm to a patient. Also called stomach cancer, when medical professionals fail to diagnose or treat it properly, patients can suffer serious consequences. Clinical negligence is when a patient’s care falls below the standard expected which directly has an impact on the patient’s health. This could be due to a delayed diagnosis or incorrect diagnosis (misdiagnosis).

If this has happened to you, we partner with medical negligence lawyers who work on a ‘No Win, No Fee’ agreement and who are available for a free, confidential consultation to discuss your case with you.

 

Gastric Cancer and Its Challenges

Early symptoms of gastric cancer often mimic common gastrointestinal complaints such as indigestion, acid reflux, stomach pain, so diagnosis is frequently delayed or missed entirely.

The chance of successful treatment depends heavily on detecting the disease early. Once the cancer advances or metastasises, the prognosis may worsen.

This makes timely diagnosis and referral critical. When a patient’s care falls below the standard expected and harms the outcome, that may amount to negligence under the law.

 

What Is Medical Negligence in Gastric Cancer Cases?

To successfully claim for gastric cancer negligence, you generally need to show:

A duty of care — the medical provider (GP, consultant, hospital) owed you a duty of care.

Breach of that duty — the provider acted below the standard expected of a competent practitioner.

Causation — the breach directly caused (or worsened) your injury or outcome.

Damages — you suffered loss (healthwise, financially, emotionally) because of the breach.

 

In gastric cancer claims, common types of negligence include:

 

Failing to take a full clinical history or missing red-flag symptoms

Failing to examine adequately or order necessary tests

Delaying referral to a gastroenterologist or specialist

Misinterpreting test results (e.g. biopsies, scans)

Failing to re-assess or escalate abnormal findings

Incorrect or unnecessary treatment that causes harm

 

Importantly, a claim will usually require demonstrating that the delay or error changed the outcome. For instance, the cancer progressed during the delay, leading to aggressive treatment or further surgery.

 

Signs That You Might Have Grounds for a Negligence Claim

Not every poor outcome is due to negligence. But these are some red flags you should watch for:

1. Persistent Unexplained GI Symptoms

If you presented repeatedly with symptoms like:

 

Upper abdominal pain or epigastric discomfort

Nausea, vomiting

Bloating or early satiety

Difficulty swallowing (dysphagia)

Unexplained weight loss

Food “sticking” in your throat

Persistent indigestion unresponsive to treatment

 

and those were dismissed or misattributed without proper investigation, that raises concern.

 

2. Failure to Investigate or Refer

If your GP or clinician never ordered:

 

Blood tests (e.g. full blood counts, LFTs)

Gastroscopy with biopsy

Imaging (CT scan of abdomen)

Specialist referral

 

despite ongoing red-flag symptoms, that omission can amount to negligence.

 

3. Misreading or Ignoring Abnormal Test Results

If test or scan results showed clear abnormalities (e.g., lesion found on endoscopy) and your physician ignored, misinterpreted, or failed to act on them, that is a red flag.

 

4. Delays in Diagnosis That Worsen Outcome

If the timeline shows that a diagnosis was delayed for months (or even years), and during that delay the cancer advanced to a more serious stage, that could support causation.

A poignant example: in one case, a woman saw her GP many times over 18 months for symptoms of nausea, abdominal pain and food “sticking,” but had no referral until she was finally diagnosed with gastric cancer –  her lawyers argued the delay deprived her of earlier treatment options.

 

5. No Offer of Explanation, Apology, or Disclosure

If the medical provider refused to explain or investigate the failure, or you only later discover the error, that may strengthen the case (though it is not sufficient on its own).

 

What You Should Do Next (Step by Step)

If you suspect medical negligence in your gastric cancer diagnosis or treatment, follow this plan:

 

1. Record and preserve evidence immediately

Keep all your medical records, test results, referrals, letters, and scan reports (your solicitor can request these).

Note down timelines: when symptoms began, dates you visited clinicians, referrals, tests, and outcomes.

Write a journal of discussions, what was (or wasn’t) explained, who you saw, and what was said.

 

2. Seek specialist legal advice 

You need an expert in medical negligence, particularly cancer misdiagnosis claims. They will assess your records and advise whether you have a viable case.

We partner with firm that offer a No Win, No Fee (conditional fee) option, meaning you do not pay upfront legal costs and only pay if your case succeeds.

 

3. Obtain independent medical expert opinion

Your solicitor will instruct independent medical experts (gastroenterologists, oncologists) to review your case. They will testify whether the standard of care fell below expectation, and whether that caused or worsened harm.

 

 4. Submit a Letter of Claim

Your solicitor will send a formal Letter of Claim to the defendant (GP practice, hospital trust, consultant) outlining your allegations, the standard of care breached, and the harm suffered. They must respond within a set timeframe.

 

5. Negotiation, Disclosure, and Mediation

The defendant may accept liability or contest it. Both sides exchange evidence (disclosure). Often mediation or settlement talks follow rather than full trial.

 

6. Litigation (if needed) and Trial

If parties cannot agree, the claim advances to court. At trial, both sides present expert evidence before a judge.

 

Compensation & Remedies

If successful, you may typically recover:

 

Costs of private or additional medical treatment

Ongoing care and rehabilitation

Loss of earnings and pension loss

Travel and out-of-pocket expenses

General damages for pain, suffering, reduced quality of life

Where relevant: funeral costs or dependency claims (if someone died)

 

Time Limits

You generally have three years from the date of the negligence or date of knowledge to bring a claim under the Limitation Act 1980.

If the claim is on behalf of someone who died, or where the victim lacked capacity, different rules can apply. It’s critical to act quickly to preserve evidence and avoid missing deadlines.

 

Challenges and Realities

Proving causation is difficult: You must show not only that negligence occurred, but that the negligence changed the outcome (i.e. you’d have had a better prognosis without the delay).

Expert disagreements: The defendant may present experts saying your cancer would have progressed anyway.

Costs and risks: Even with No Win, No Fee, there may be disbursement costs (e.g., expert fees) and risk that you pay defendant’s costs if you lose (though many agreements protect against that).

Emotional burden: Pursuing a legal claim while coping with cancer or its effects is stressful. A supportive solicitor is key to managing your claim.
