Your GP kept dismissing your symptoms — and now you have bowel cancer. What are your options?
You went back more than once. You described the same symptoms — or symptoms that were getting worse. You were told it was probably IBS, stress, haemorrhoids, or something dietary. And then, eventually, someone found bowel cancer.
The question you are now carrying is not abstract. It is specific and it is urgent.
This article explains what GPs are required to do when a patient presents with bowel symptoms, where that standard is most commonly breached, and what the steps are if you want to find out whether the delay in your diagnosis was avoidable.
What your GP was required to do
Australian GPs follow clinical guidelines that set out when bowel symptoms require investigation and when a patient should be referred for colonoscopy or specialist review. A GP who sees a patient with rectal bleeding, a change in bowel habit, unexplained weight loss, or persistent abdominal symptoms is required to take those symptoms seriously — not reassure the patient and wait.
The standard does not require a GP to diagnose cancer. It requires them to recognise a pattern of symptoms that could indicate cancer and act on that possibility in a timely way.
A 52-year-old woman visited her GP three times over fourteen months with rectal bleeding and fatigue. Her GP attributed the bleeding to haemorrhoids on each occasion and ordered no further investigation. On her fourth visit, a different GP referred her for colonoscopy. The colonoscopy found a stage III colorectal tumour. At stage I, the five-year survival rate exceeds 90 per cent. At stage III, it falls to around 70 per cent.
Dismissing rectal bleeding without investigation
Rectal bleeding in a patient over 40 — or in a younger patient with a family history of bowel cancer — requires investigation, not assumption. A GP who attributes bleeding to haemorrhoids without ruling out a more serious cause has not met the required standard.
The failure is not in the initial attribution. It is in the failure to investigate when the symptom persists, recurs, or appears alongside other warning signs. Each visit where the GP reassured rather than referred is a point the records will show.
Attributing symptoms to IBS or anxiety without ruling out cancer
A change in bowel habit — looser stools, increased frequency, or alternating constipation and diarrhoea — is a recognised warning sign for colorectal cancer. GPs are required to consider that possibility before settling on a functional diagnosis like IBS.
When a GP labels symptoms as IBS or stress-related without ordering a faecal occult blood test, a colonoscopy referral, or any investigation, and the patient later receives a bowel cancer diagnosis, the question is whether that label delayed the diagnosis by months or years.
Failing to act on a patient’s age and risk profile
Age is a significant risk factor for bowel cancer. So is a family history of colorectal cancer or polyps. A GP who treats a 55-year-old with persistent bowel symptoms the same way they would treat a 25-year-old has not applied the required clinical judgment.
The records will show whether the GP documented the patient’s age, family history, and symptom duration — and whether those factors changed the clinical response. Often, they did not.
- You presented to your GP with bowel symptoms — rectal bleeding, changed bowel habit, abdominal pain, or unexplained weight loss — on more than one occasion before receiving a cancer diagnosis.
- Your GP attributed your symptoms to haemorrhoids, IBS, stress, or diet without ordering any investigation or referring you to a specialist.
- You were over 40, or had a family history of bowel cancer, and your GP did not factor that into their clinical response.
- Your cancer was diagnosed at a later stage than it would have been if investigation had begun at your first or second presentation.
- You raised your concerns with your GP — told them the symptoms were not improving — and they still did not refer you.
- This happened some years ago and you have only recently started to wonder whether the delay was avoidable — perhaps after a conversation with a specialist, or after reading about someone else’s experience.
The records — not anyone’s memory of those appointments — will answer whether the standard of care was met. Many people wait years before looking into this, and the time limit for making a claim varies by state and territory in Australia, so the timing of when you act matters.
What the next step actually involves
A legal review of a missed diagnosis claim starts with the medical records — the GP notes, referral history, test results, and the eventual diagnosis. Those records show the timeline: when you first presented, what the GP recorded, what they ordered, and what they did not do.
The goal of that review is an honest answer. Not to find fault for its own sake — but to determine whether a GP acting to the required standard would have referred you sooner, and whether an earlier referral would have changed your outcome.

Her legal background allows her to read medical records — and then apply the law to what she finds. For missed bowel cancer diagnoses, that perspective matters: the failures that cause harm often sit in the gap between what the GP recorded and what the patient was told at each appointment.
Dr Listing’s work is focused on giving people an honest answer about whether what happened to them was avoidable. Many people wait a long time before looking into it. She understands why and applies a sensitive and caring approach to all her clients’ cases.
