When a Misdiagnosis Changes Everything: A Medical Malpractice Scenario

The following is a hypothetical scenario for educational purposes. It does not represent any actual case or real individuals.

The Scenario

A 52-year-old Thurston County resident — we will call her Maria — visits her primary care physician in Olympia with persistent stomach pain, unintended weight loss, and difficulty swallowing. She has had these symptoms for about six weeks and they are getting worse.

Her doctor performs a brief physical exam, diagnoses her with gastroesophageal reflux disease (GERD), and prescribes a proton pump inhibitor. He tells her to avoid spicy foods, elevate her head at night, and come back if it does not improve in a few weeks.

Maria follows the instructions. The medication helps slightly with the burning sensation, but the weight loss continues. She returns two months later. Her doctor adjusts the dosage and tells her to give it more time.

Four months after her first visit, Maria is in significantly worse shape. She has lost 25 pounds. She can barely eat. A friend urges her to see a different doctor.

The new physician orders an upper endoscopy within a week. The results come back: stage III gastric cancer. If it had been caught at her first visit — when the symptoms were already present — it would likely have been stage I, with a five-year survival rate above 70%. At stage III, that rate drops dramatically.

Maria's original doctor never ordered an endoscopy. He never ordered imaging. He never referred her to a gastroenterologist. He attributed every symptom to acid reflux and sent her home.

Was This Medical Malpractice?

Under Washington law (RCW 7.70), a medical malpractice claim requires four elements. Let us walk through each one as it applies to Maria's hypothetical situation.

1. A Provider-Patient Relationship Existed

Maria was an established patient of her primary care physician. He examined her, diagnosed her, prescribed treatment, and saw her for follow-up. There is no question that a provider-patient relationship existed, and with it, a duty of care.

2. The Provider Breached the Standard of Care

This is the core question in any malpractice case: did the doctor do what a reasonably competent physician in the same specialty would have done under the same circumstances?

Maria presented with a constellation of symptoms — persistent epigastric pain, dysphagia (difficulty swallowing), and significant unintended weight loss. In combination, these are well-recognized alarm symptoms that warrant further investigation. Medical guidelines widely recommend that patients presenting with these red flags receive prompt referral for endoscopy or other diagnostic workup to rule out malignancy.

A reasonably prudent primary care physician, confronted with the same symptoms in a 52-year-old patient, would not simply prescribe a PPI and send her home without further evaluation. The failure to order appropriate diagnostic testing or refer Maria to a specialist — especially after her symptoms persisted and worsened at the follow-up visit — represents a deviation from the accepted standard of care.

3. The Breach Caused Harm

This element requires showing that the doctor's failure directly caused Maria's injury. The injury here is not the cancer itself — the doctor did not cause the cancer. The injury is the delay in diagnosis and the resulting loss of treatment opportunity.

Had the cancer been detected at Maria's first visit, it would likely have been at an earlier, more treatable stage. The delay allowed the cancer to progress from a stage with favorable survival odds to one with significantly worse outcomes. Maria lost months of potential treatment time because her doctor failed to investigate.

In Washington malpractice cases, this is sometimes framed as "loss of chance" — the patient lost a meaningful chance at a better outcome due to the provider's negligence. Washington courts have recognized loss of chance as a viable theory of harm in medical malpractice cases.

4. Maria Suffered Actual Damages

The damages in a delayed cancer diagnosis case can be enormous:

• Additional medical costs: Stage III cancer requires more aggressive treatment — chemotherapy, possible surgery, radiation, extended hospital stays — that may not have been necessary with an earlier-stage diagnosis.
• Lost income: Maria may be unable to work during extended treatment. If the cancer proves terminal, she loses all future earning capacity.
• Pain and suffering: The physical pain of advanced cancer treatment, combined with the emotional anguish of knowing the disease could have been caught earlier, constitutes significant non-economic damages.
• Reduced life expectancy: If the delayed diagnosis shortened Maria's life, her estate and family may have claims for wrongful death.
• Loss of quality of life: Even if Maria survives, her quality of life during and after aggressive treatment for advanced cancer is dramatically worse than it would have been with early-stage intervention.

How This Case Would Proceed in Washington

Step 1: Medical Record Review and Expert Consultation

The first step would be obtaining Maria's complete medical records from both the original physician and the subsequent provider who made the correct diagnosis. A qualified medical expert — typically an oncologist or gastroenterologist — would review those records to confirm that the original doctor deviated from the standard of care and that earlier diagnosis would have made a material difference in outcome.

Step 2: Filing the Lawsuit

The lawsuit would be filed in Thurston County Superior Court.

Step 3: Discovery and Expert Testimony

Medical malpractice cases in Washington require expert testimony to establish both the standard of care and the breach. Maria's legal team would retain qualified experts to testify about what a competent physician should have done, and an oncology expert to testify about how earlier detection would have changed her prognosis.

The defense would retain their own experts. These cases are vigorously contested.

Step 4: Resolution

The case would ultimately resolve through settlement negotiation or trial. Medical malpractice cases involving delayed cancer diagnosis — particularly where the delay is well-documented and the outcome difference is clear — can result in substantial compensation.

The Takeaway: Trust Your Instincts

Maria's story, while hypothetical, reflects a pattern that plays out in medical malpractice cases across Thurston County and throughout Washington. A patient knows something is wrong. A doctor offers a quick diagnosis without digging deeper. The patient trusts the doctor. Time passes. And by the time the real problem is found, the window for optimal treatment has narrowed or closed.

If you are experiencing symptoms that are not improving despite treatment, if your doctor is not ordering tests that seem warranted, if something simply does not feel right — get a second opinion. And if that second opinion reveals that something should have been caught earlier, you may have a medical malpractice claim.
