How Kidney Cancer Misdiagnosis Happens and When it May be Classed as Negligence | Nash & Co Solicitors
Written by Mike Shiers and Rebecca Brisley | Medical Negligence team | 18 February 2026
When symptoms persist or worsen, most people trust that their GP or hospital will investigate thoroughly and act on warning signs. With kidney cancer, that trust is particularly important because early symptoms are often subtle and easily overlooked.
Kidney cancer misdiagnosis occurs when the disease is missed, mistaken for another condition, or diagnosed later than it reasonably should have been. In some cases, this delay can affect treatment options and long-term outcomes. While not every missed diagnosis is negligent, there are situations where failures in care fall below acceptable standards.
What this article will cover
This article explains how kidney cancer is commonly misdiagnosed, why delays happen, and when those delays may amount to medical negligence. It also outlines what to do if you suspect a diagnosis was missed and how Nash & Co Solicitors supports people across Plymouth, Devon, Cornwall, and the UK who are seeking answers.
Why kidney cancer is often difficult to diagnose
Kidney cancer can be challenging to identify in its early stages. Symptoms may be vague, intermittent, or attributed to more common conditions. Some people experience no clear symptoms at all until the cancer has progressed.
Common symptoms that may be overlooked include blood in the urine, persistent lower back or side pain, unexplained fatigue, or recurrent urinary infections. When these signs are treated in isolation without further investigation, opportunities for earlier diagnosis can be missed.
How kidney cancer misdiagnosis commonly occurs
Misdiagnosis is rarely caused by a single mistake. More often, it results from a series of missed opportunities or failures within the diagnostic process.
This may include situations where symptoms are repeatedly treated as minor or unrelated, scans are not arranged promptly, or abnormal findings are not followed up. In busy clinical settings, test results can be delayed, misinterpreted, or not communicated clearly between departments.
In kidney cancer cases, imaging plays a critical role. Ultrasounds, CT scans, and MRI scans are often required to identify tumours. When these are not ordered at the appropriate time or are incorrectly interpreted, diagnosis can be significantly delayed.
Common diagnostic failures in kidney cancer cases
The following issues are frequently seen in kidney cancer misdiagnosis claims:
Failure by a GP to refer a patient for urgent imaging despite ongoing or worsening symptoms
Delays in arranging or reporting scan results
Misinterpretation of imaging by radiology staff
Failure to act on incidental findings where a kidney abnormality was noted on a scan carried out for another reason
Each of these failures can contribute to a delay that affects treatment options.
When kidney cancer misdiagnosis may amount to medical negligence
Not every delayed diagnosis is negligent. To establish medical negligence, it must be shown that the care provided fell below the standard expected of a reasonably competent medical professional, and that this failure caused avoidable harm.
For example, negligence may be identified where a GP failed to investigate blood in the urine appropriately, or where a scan clearly showed abnormalities that were not acted upon. If another competent professional would have referred the patient sooner or arranged further testing, there may be grounds for a claim.
Independent medical experts are used to assess what should have happened at each stage of care and whether earlier diagnosis was achievable.
The impact of delayed kidney cancer diagnosis on treatment
Delayed diagnosis does not automatically mean a worse outcome, but it can limit available treatment options. Kidney cancer identified at an earlier stage may be managed with less extensive surgery or treatment.
When diagnosis occurs later, treatment may involve more complex surgery, additional therapies, or prolonged monitoring. These practical consequences are central to assessing whether compensation may be appropriate in a medical negligence claim.
What to do if you suspect kidney cancer was misdiagnosed
If you believe your kidney cancer diagnosis was delayed or missed, it is important to seek specialist legal advice as early as possible. Early advice allows medical records to be obtained while information is still available and timelines are clearer.
You may find it helpful to gather details of symptoms, appointments, referrals, and test results. A specialist in kidney cancer misdiagnosis claims can review this information and advise whether the care provided fell below acceptable standards.
How compensation claims for kidney cancer misdiagnosis work
Kidney cancer medical negligence claims focus on the practical impact of delayed diagnosis. Compensation is intended to reflect additional treatment requirements, ongoing care needs, and financial consequences linked to the delay.
Each claim is assessed individually. Independent medical evidence is central to establishing whether earlier diagnosis would have changed the course of treatment and what additional needs arose as a result of the delay.

-
It occurs when kidney cancer is missed, diagnosed too late, or mistaken for another condition.
-
Yes, if the delay was caused by negligent care and resulted in additional treatment or impact.
-
Generally, you have three years to bring a medical negligence claim but when this starts depends on your specific circumstances.
In some cases, the time runs from the date the negligence and harm were obvious, while in others it runs from your date of knowledge, meaning when you knew or reasonably ought to have known that negligent treatment had caused you harm, such as the date of a delayed cancer diagnosis.
This test is fact specific and varies by case so it is important to seek legal advice as soon as possible to protect your position.
-
No. It must be shown that the care fell below acceptable standards and that another professional would have acted differently.
-
Yes. We act for clients across Devon, Cornwall, and throughout the UK.
