Advanced prevention and early detection of cancer

Estimated reading time: 4 minutes

Advanced prevention and early detection of cancer encompass modern, targeted medical strategies that go beyond general healthy living advice. These methods focus on identifying high-risk individuals and catching the disease at its earliest, most curable stages, often under the remit of the NHS or specialist services.

Key Takeaways

Tailored prevention beyond general advice

Advanced prevention is highly personalised and often relies on medicines, known as chemoprevention, to reduce cancer risk for people identified as high-risk, following NICE guidelines. This approach is tailored using sophisticated tools like genetic testing and polygenic risk scores, going far beyond simple family history. For example, drugs like Tamoxifen are offered to women at high familial risk of breast cancer.

Liquid biopsies are the new blood test screening

Early detection is being revolutionised by liquid biopsies. These groundbreaking blood tests search for tiny fragments of circulating tumour DNA (ctDNA). The NHS is already rolling out this technology to speed up treatment for some cancers. Further UK trials are also evaluating these multi-cancer early detection (MCED) tests for screening the general public.

Technology and recurrence management

Technology is enhancing both prevention and recurrence management. Artificial intelligence is improving the reliability of existing NHS screening programmes by spotting subtle changes in imaging. Similarly, detecting minimal residual disease (MRD) by finding ctDNA post-treatment allows doctors to proactively intervene and stop cancer from coming back, which is a form of tertiary prevention.

Advanced prevention of cancer

This proactive approach using drugs or personalised risk profiles to stop the development of cancer. Particularly in people with a high inherent risk, as defined by NICE (National Institute for Health and Care Excellence) guidelines.

Chemoprevention

Chemoprevention uses medicines to actively prevent, suppress, or reverse cancer progression. For example, NICE suggests clinicians offer drugs to women who face a moderate or high familial risk of breast cancer. These include Tamoxifen (for pre- or post-menopausal women) or Anastrozole (for post-menopausal women). A specialist always makes this decision, weighing the benefits against side effects like blood clots.

Personalised risk assessment

Risk is determined using sophisticated data. This goes beyond simple family factory. This includes genetic testing for mutations via NHS Genomic Medicine Services. It also involves calculating polygenic risks scores from an individual’s full genetic blueprint. Such analysis helps specialist clinicians tailor screening or preventative interventions early.

Early detection

Early detection focuses on finding the disease while it is tiny and asymptomatic. This greatly improves the changes of successful outcome within the NHS.

Liquid biopsy / multi-cancer early detection tests

These are groundbreaking blood tests. They search for minute fragments of circulating tumour DNA shed by early-stage tumours. The NHS is currently rolling out liquid biopsy for patients with lung and advanced breast cancers. This speeds up access to targeted treatment. More widely, large-scale clinical trials are underway in the UK. This includes the NHS-Galleri trial. These trials evaluate the effectiveness of multi-cancer early detection tests for screening the public or many different cancers simultaneously.

Minimal residual disease detection

Although often used after initial treatment, this is a form of tertiary prevention. By detecting minute traces of circulating tumour DNA in the blood post-surgery, doctors can identify high-risk patients. This allows them to start further treatment earlier. The goal is to stop the cancer from coming back. This is a key area of UK cancer research.

Advanced imaging and screening

The NHS runs three national screening programmes (Bowel, breast and cervical). Artificial intelligence is increasingly used in UK pathology and radiology. It analyses images (mammograms, CT scans) to spot subtle changes. This makes existing NHS screening programmes more sensitive and reliable.
