Early cancer detection

The ability to detect cancer at its earliest stage is the single most important factor determining treatment success and long-term survival. This crucial advantage is key to preserving a client’s quality of life and dignity.

Key Takeaways

Survival rates soar with early detection

Finding cancer when it is small and localised significantly increases the chance of cure, with 5-year survival rates for cancers like bowel and breast cancer being nearly universal when diagnosed at the earliest stage, but dropping sharply when found late.

National strategy targets early diagnosis

The NHS is prioritising early detection, aiming to diagnose 75% of all cancers at Stage 1 or 2 by 2028. This is achieved through targeted screening programs, such as Lung Health Checks (TLHC) for smokers and the Simple Stool Test (FIT) for symptomatic patients, to efficiently manage high-risk groups.

Non-invasive technologies promise a future of prevention

Academic research is pioneering revolutionary diagnostics that detect subtle DNA clues in the blood. This includes tests that exploit the immune system as an early warning system, and low-cost, patient-friendly devices, such as the swallowable camera.

The goal of early cancer prevention

The goal of early detection is straightforward – to find cancer while the tumour is small and localised – before it spreads to other parts of the body. When cancer is found early, treatment is often less invasive and significantly more effective.

The significant impact of early diagnosis can be seen in the five-year survival rates for cancer. The difference between finding a cancer at its earliest stage (Stage 1) versus its most advanced stage (Stage 5) is immense:

• Breast cancer

Almost all women diagnosed at the earliest stage survive for five years or more. This rate typically decreases to 3 out of 10 when diagnosed late.

• Bowel cancer

For early diagnosis, over 9 out of 10 people survive for five years or more, with rate dropping down to 1 out of 10 when diagnosed late.

• Lung cancer

If diagnosed early, around 6 out of 10 people survive five years or more. This falls to less than 1 out of 10 when diagnosed at the most advanced stage.

These numbers from Cancer Research UK prove that preventing the cancer from spreading is the main battle. An early diagnosis often allows for localised treatments, such as surgery. This is reduces the need for intensive chemotherapy or extensive radiotherapy. Further benefits are reduction in physical and emotional stress of treatment and helping the client maintain their independence, routine, and dignity.

Difference between diagnosis and screening

According to the World Health Organisation, effective cancer control uses two distinct approaches:

1. Early diagnosis

Considered the simpler strategy, focuses on quickly identifying cancer in people who are already showing symptoms. This approach helps symptomatic patients get treatment as soon as possible.

2. Screening

More complex, involves testing a population who appear healthy and have no symptoms for unrecognised disease. Only recommended when a country has the resources, infrastructure, and ability to provide effective treatment for everyone with diagnosis. An approach designed to detect cancer before symptoms begin.

New pathways for early diagnosis

The NHS has made early detection a priority, and has rolled out specific programs to improve cancer survival rates. The main goal of the national cancer strategy is to diagnose 75% of all cancers at Stage 1 or 2 by 2028. This requires streamlining how patients are referred and diagnosed, with local GP practices playing a key role in ensuring patients are referred fast and encouraging the use of screening programs.

Targeted Lung Health Checks (TLHC)

• Specifically aimed at the population most likely to get lung cancer – current or former smokers aged 55 to 74
• Participants answer a lifestyle questionnaire and may be invited for a low-dose CT scan, which takes a detailed picture of the lungs
• The program has had a high success rate, finding 76% of cancers at an early stage (Stage 1 or 2)

Simple stool test (FIT) for bowel cancer

• For patients who visit their GP with potential bowel cancer symptoms, the NHS uses a tool called the Faecal Immunochemical Test (FIT)
• It is a simple, non-invasive stool test, helps the GP quickly assess the level of risk
• Allows doctors to effectively manage complex diagnostic pathways; helps GPs decide if an individual needs an urgent examination, such as colonoscopy
• Ensures effective use of equipment and time for patients in high risk

Focus on liver cancer

• Aims to focus on closely monitoring high-risk individuals
• Testing ways to find at-risk people in their communities, using scans called Fibroscans, then enrolling them into regular, high-quality surveillance programs
• The goal is to detect these cancers when they are small and curable

Non-invasive technologies

The Early Cancer Institute at Cambridge is focused on developing new detection technologies that are highly sensitive and scalable, often using non-invasive methods.

Looking for DNA clues in the blood

Researches are using advanced machine learning to analyse DNA to create cancer exposure or development.

Exploiting the immune system

Area of research that involves using the body’s immune system as an ultra-sensitive early warning system. Testing aims to indicate pre-cancerous change long before any symptoms appear.

The swallowable camera

The institute is developing a swallowable camera which eliminates the need for anesthesia and can be administered by a nurse in local clinics. This makes large-scale screening far more feasible and less intrusive for the patient.

Tiny devices for blood cancer screening

Researchers are miniaturising diagnostic tool into a disposable chip devices, allowing for routine screening of early cancer markers outside of major hospitals.

In summary

The collective efforts of the NHS strategies and pioneering academic research are successfully steering us toward a future of prevention. This means we are increasingly able to detect cancer at its earliest, most curable stages, dramatically improving the prognosis for generations to come.
