Cancer Misdiagnosis Claims
A cancer diagnosis can be devastating. This can be made even more difficult to deal with if your cancer was misdiagnosed, diagnosed too late, or even preventable. But you’re not alone in this. Our experts can be your advocate, getting you the answers and compensation you need to move forward.

We help you make a claim if earlier diagnosis and treatment would have changed your prognosis
Diagnosing and treating cancer at an early stage can be lifesaving. Sometimes, medical professionals make mistakes and recognise symptoms too late.
A cancer misdiagnosis can have a serious impact on your life. Misdiagnosed cancer can result in more invasive treatment, or the cancer spreading or becoming terminal. We’ve seen the impact this has on people who are already going through so much. We’re ready to stand in your corner and get to work so you get the compensation you deserve.
Our expert lawyers have helped thousands of people claim after a cancer misdiagnosis. With understanding and sensitivity, we will work to get answers from those responsible because we know moving on isn’t just about compensation, it’s about accountability.
How can cancer be misdiagnosed?
Cancer can be misdiagnosed because its symptoms are shared with non-fatal, benign conditions. It can also be missed because of diagnostic errors such as misreading CT scans.
Common reasons for cancer being misdiagnosed includes:
- Symptom overlap: Cancer symptoms are often the same as less-severe diseases. For example, lung cancer can be diagnosed as bronchitis at first.
- Image/testing errors: A radiologist may misread your scans (X-rays or CT scans) or your tissue samples might be misread.
- False positives/negatives: Screening tests can sometimes show false negatives, which misses the cancer, or false positives, which identifies something wrongly as cancer.
- Diagnostic overshadowing: A doctor might wrongly diagnose new and serious symptoms to an existing condition and decide against further investigation.
- Communication failure: A delay in your referral to a specialist.
What cancers are commonly misdiagnosed?
Most types of cancer have symptoms that are the same or similar to those from non-cancerous conditions. This means that your cancer could be misdiagnosed.
We may be able to help with your claim if you have experienced one of the following misdiagnoses:
- Breast cancer: Like other inflammatory breast conditions, such as mastitis (painful and inflamed breast tissue) and fibrocystic breast disease (benign lumps in the breast).
- Bowel cancer: This can be confused with irritable bowel syndrome (IBS) and inflammatory bowel diseases like Crohn’s Disease and Ulcerative Colitis.
- Lung cancer: Signs can be mistaken for lung infections including bronchitis, tuberculosis, and pneumonia.
Thorough checks and referrals for specialist tests can help avoid cancer misdiagnosis. Healthcare professionals should know the tell-tale signs of cancer, and they should know the importance of acting quickly to detect cancer early.
We are here to help if you have suffered because of cancer misdiagnosis. We can help you get compensation and rehabilitation to make your life easier.
Cancer misdiagnosis claim scenarios
Asbestos-related lung cancer claims
Developing a work-related illness or cancer is an injustice that nobody deserves. We’ll work hard to get you answers and compensation.
Exposure to asbestos is known to cause several types of lung disease including pleural thickening, asbestosis, and mesothelioma. There’s a strong link with lung cancer, too. You are most at risk of asbestos exposure if you worked in certain jobs, such as:
- Metal workers
- Plumbers
- Gas fitters
- Electricians
- Carpenters
- Fitters
- Textile workers
- Railway engine and carriage builders.
The symptoms of asbestos exposure can take decades to appear, but you can still make a claim, even if the company you worked for is no longer in business.
Breast cancer screening claims
If the NHS breast cancer screening appointment failure caused your late diagnosis, we could help you get answers and claim compensation.
All women aged 50 to 70 are entitled to breast cancer screening every three years.
However, from 2009 to 2018, a serious computer error meant NHS England’s appointment booking system failed to schedule final screening appointments for around 450,000 women. Some of these women may have experienced late diagnosis of breast cancer leading to more difficult treatments and reduced life expectancy.
If you believe you were affected by this, our experienced medical negligence solicitors could help you claim compensation.
