The purpose of this guide is to help anyone who has suffered a cancer misdiagnosis and is considering a legal claim for compensation. If you are looking for medical advice, please see the NHS website.

In our guide to claiming cancer misdiagnosis compensation:


According to Cancer Research UK, there are around 367,000 new cancer diagnoses each year. Over half (53%) of these were skin, breast or prostate cancers.

Rates of cancer diagnosis have increased by 5% in the last decade.

It is important that cancers are detected as early and as accurately as possible to give patients the best chance of recovery. If a cancer is misdiagnosed it may result in wrong or delayed treatment, with potentially severe consequences.

Only a quarter of cases are diagnosed at the earliest stage, Stage 1.

What is cancer misdiagnosis?

Many illnesses present with similar clinical features to cancer in the early stages, and it may be difficult to determine the cause of a patient's symptoms.

Medical professionals should use differential diagnostic procedures to identify the patient's condition and eliminate potentially life-threatening conditions.

A medical professional, such as a GP, may fail to recognise that his or her patient's symptoms potentially indicate that cancer is a possible diagnosis. The GP may fail to carry out appropriate tests or consult with specialists to investigate the condition further. As a result, they may mistakenly provide an incorrect diagnosis for the patient's illness. This is referred to as clinical negligence.

Even where tests have been carried out, faulty lab equipment or human error may result in inaccurate reports from the laboratory or clinic.

A cancer misdiagnosis may lead to incorrect or delayed treatment, and the subsequent and avoidable worsening of the patient's condition.

In extreme case, the error may be discovered too late to offer effective treatment.

Do I have a cancer misdiagnosis claim?

Medical negligence claims differ from personal injury claims as the following will need to be established:

  • there was a breach of duty ("negligence" or "fault"); and
  • the breach of duty was the cause of your injury, damage or loss ("causation" or "avoidable harm").

Breach of Duty

A breach of duty means that the standard of care you received was below the standard that could reasonably be expected of a competent healthcare professional.


To establish causation, it will need to be demonstrated that the injury you suffered resulted from the negligent care rather than the underlying condition.

Get an impartial opinion

To get impartial advice on whether you have a claim, speak to a cancer misdiagnosis claim expert on 0800 376 1001.

A brief phone consultation will tell you exactly where you stand. There is no obligation to start a claim.

Is compensation always payable?

If an error occurred during treatment and the patient was harmed as a result, this may be referred to as an "undesirable outcome".

Not all treatment that results in an undesirable outcome will result in the payment of compensation.

Sometimes an undesirable outcome is due to a known risk associated with the treatment, or due to a mistake that a doctor could reasonably have made in the circumstances.

How long do I have to start a claim?

If your injury is apparent immediately after medical treatment, you will have 3 years to start a claim.

It may be that the negligent procedure happened more than 3 years ago, but your injury was only diagnosed recently, within the last 3 years. If so, you may still be able to make a claim.

What if your injury was diagnosed months or years after treatment?

You may not be immediately aware of your injury. In some cases, months and even years can pass before symptoms appear.

The law allows you to make a medical negligence claim up to three years after the 'date of knowledge' (when you first learned of the injury).

It is recommended that you start a claim as soon as possible, as medical negligence cases can be complex. Starting your claim sooner will give your solicitor more time to gather medical evidence, assess the extent of your injury and to negotiate interim payments and your final compensation amount.

How long does the misdiagnosis need to have lasted?

It must be proved that the misdiagnosis caused harm to the patient or worsened their condition.

In the event that a misdiagnosis is spotted after only a relatively short period, and so the cancer has not spread or developed to a later stage, it may not be possible to claim compensation. This will be decided based on the medical evidence and facts of the case.

Evidence of cancer misdiagnosis

All relevant evidence of the misdiagnosis must be kept. This includes any records or statements made by medical professionals and any prescriptions issued.

Notes of any financial losses, such as travelling costs and loss of earnings if unable to work, should be documented as they will form the basis of any claim for "special damages".

Can I claim if I have been wrongfully diagnosed with cancer?

In rare cases, patients have been diagnosed as having cancer, when in fact they did not.

Wrongful diagnosis can result in serious emotional and physical consequences that persist long after the error has been identified.

The perception of cancer as particularly harmful can amplify the emotional fallout of a diagnosis. A patient may be able to claim compensation for psychological trauma, stress and depression sustained as a result of the medical error.

Treatments for cancer including chemotherapy and radiotherapy can carry a range of risks and come with significant side-effects. Unnecessary exposure can permanently affect a patient's health and will mean that the correct treatment for the patient's true illness or condition is delayed.

Surgery also carries risks, and can result in irreversible, long-term physical and psychological harm in the case of the removal of breasts or sections of kidney, lung or bowel tissue.

How much compensation can I claim for cancer misdiagnosis?

The amount of money you could claim for your cancer misdiagnosis will depend on:

  • the extent of your injury, and
  • any financial losses or costs you have incurred.

At the start of your claim, your solicitor will consider the many ways your cancer misdiagnosis has affected your life. Your solicitor will take all of these effects into account to calculate the correct compensation award for you.

This calculation will factor in 'general damages' and 'special damages'.

General damages

General damages are awarded for pain, suffering and loss of amenity (PSLA).

Awards for general damages are set by the Judicial College and published in their guidelines for personal injury awards.

Special damages

Special damages are for financial losses and expenses you have incurred as a result of the accident.

What can I claim for after a cancer misdiagnosis? (see list)

Examples of special damages (losses you can claim for) include:

  • Lost earnings (including future earnings)
  • Medical treatment costs
  • Physiotherapy
  • Travel costs
  • Costs of care
  • Costs of adapting your home or car

What is the average injury compensation for a cancer misdiagnosis claim?

The Judicial College injury tables give a approximate idea of the ranges awarded for different injuries.

However, the money you would receive following a cancer misdiagnosis will depend entirely on your specific circumstances.

Your cancer misdiagnosis compensation will be calculated based on the unique impact your injuries have had on your life and your ability to work, and on the actual financial losses you have incurred as a result of your injuries.

Will I have to pay tax on my cancer misdiagnosis compensation?

If you receive financial compensation following a cancer misdiagnosis injury, specific legislation ensures that you do not have to pay tax on it. This is the case no matter whether the compensation is received as a lump sum or as staggered payments.

Cancer misdiagnosis FAQ's

Can I claim for someone else?

Yes. In certain circumstances, it is possible to claim compensation on behalf of another person in the capacity of a 'litigation friend'.

If an injured person is either too young or vulnerable, too injured or otherwise unable to claim on their own behalf, their litigation friend can handle the claim process on behalf of the injured person.

The litigation friend will be responsible for communicating with the solicitors, and for making decisions in respect of the claim.

Read more about claiming on behalf of another person.

Will I have to go to court?

Highly unlikely. The vast majority of claims that are settled by the solicitor panel are settled out of court.

Only a very small percentage (approx. 5%) of personal injury claims go to court. Generally, only very complex cases, or those where liability cannot be resolved, end up in court.

Cases that do ultimately go to court are held in front of a judge, not a jury.

Will I have to go to a solicitor's office?

No. You will not need visit a solicitor's office. As with most professional services, it is no longer necessary to meet face to face with your solicitor. Personal injury claims are dealt with via email, post and telephone.

Should you need to have a medical, this will be arranged at a medical centre near you or at your GP's surgery.

Can I get an early compensation payment?

If you suffer financial hardship as a result of an injury, you may be able to claim an interim compensation payment.

An interim payment is a partial settlement of your claim which is paid before your claim is concluded. The amount you receive in interim payments would then be deducted from your final compensation settlement or award.
