Cancer misdiagnosis claims

Being diagnosed with cancer can be devastating. We can help with a compensation claim.

Being diagnosed with cancer is devastating for you and your family. But if you’ve been given a delayed cancer diagnosis or a misdiagnosis of cancer you may be able to bring a medical negligence claim.

An average of 363,000 new cancer cases are recorded in the UK every year. Cancer is more likely to be treated successfully if it’s detected early. However, around 115,000 cancer patients in England are diagnosed too late to give them the best chance of survival.

Delayed cancer diagnosis

Late diagnosis of cancer can have a devastating effect on your health, as any delay in treatment may allow more time for the cancer to spread. A hold up in the identification of your condition could be considered clinical negligence if a medical professional misses your symptoms and fails to provide the correct cancer diagnosis.

This can have a knock-on effect that slows down the process of organising medical care and could lead to late cancer treatment. In severe cases, this can come too late and sadly result in an avoidable or early death.

The COVID-19 pandemic saw the suspension of cancer screening for a certain period, with only urgent symptomatic cases prioritised for diagnosis . Its long-term impact is yet to be fully realised, but for some individuals it could have serious consequences, resulting in late cancer diagnosis.

Whatever the circumstances of your case, you may be able to claim for delayed or missed cancer diagnosis compensation if you believe medical negligence resulted in your late diagnosis of cancer and its subsequent effects on your health.

Misdiagnosis of cancer FAQs

Can cancer be misdiagnosed?

There are more than 200 cancer types, so misdiagnosis of cancer can sometimes occur. Many cancers share similar symptoms with other illnesses. As a result, doctors and medical professionals can sometimes make an incorrect diagnosis.

How common is cancer misdiagnosis?

Misdiagnosed cancer is relatively common – in fact, it’s believed to be on the rise. Research has found that four out of 10 patients with cancer in the UK receive the wrong diagnosis of cancer at least once before their disease is correctly diagnosed.

Some of the most common cancers thought to be misdiagnosed7 due to their symptoms being linked to another illness include:


•  Breast cancer
•  Lung cancer
•  Pancreatic cancer
•  Colorectal cancer

What counts as a late cancer diagnosis?

A late diagnosis of cancer is any situation where a patient showing symptoms fails to have them identified. There can be various reasons behind a delayed cancer diagnosis:


•  The patient doesn’t recognise and report the symptoms early on.
•  A doctor fails to identify the symptoms as cancerous at first, delaying the correct diagnosis.
•  Medical cancer checks are pushed back due to long waiting lists, administration mistakes or other errors.

In any case, a delay to cancer treatment often means the disease could spread further, reducing the chance of the patient’s survival and increasing subsequent treatment costs. If you can prove your delayed cancer diagnosis was caused by medical negligence, then you may have a claim.

Can I sue for cancer misdiagnosis?

Whether you had NHS or private treatment and received a misdiagnosis or delayed cancer diagnosis, you should be able to claim for medical negligence.

There are two main types of cancer misdiagnosis you can
make a claim for:


•  Undiagnosed – when a doctor or medical professional fails to spot the cancer.
•  Incorrect – when you receive treatment for the wrong illness after a doctor or medical professional misreads the signs of cancer.

How much compensation can I get for cancer misdiagnosis?

Cancer misdiagnosis compensation amounts vary depending on the case. This can differ based on factors including:


•  The severity of the consequences from the misdiagnosis.
•  How long the cancer went undiagnosed.
•  Financial losses you experience due to the misdiagnosis.

Can I make a cancer misdiagnosis claim for someone else?

When a loved one has died due to misdiagnosis of cancer, it’s possible to recover compensation on their behalf. You may be able to claim if you are the spouse or child of the victim, or if you’re the parent of a child. Often there is a three-year time limit after the date of the death to make a claim.
