For years, cancer detection has relied on traditional methods like invasive biopsies and imaging, often leading to delayed diagnoses. But in 2025, AI-powered liquid biopsies are breaking new ground. By analysing tumour DNA circulating in the bloodstream, these non-invasive tests can detect lung and breast cancers earlier and more accurately than ever before.
This revolutionary approach combines the power of artificial intelligence with leading-edge genetic profiling to offer personalised treatment options tailored to each patient’s unique genetic makeup. In this blog, we’ll dive into how this breakthrough technology is changing the landscape of cancer care, bringing us one step closer to smarter, faster, and more effective cancer detection.
What is Liquid Biopsy?
A liquid biopsy involves a simple blood test to detect cancer-related mutations in the DNA or RNA shed by tumour cells. Unlike traditional biopsies, which require tissue samples from the tumour, liquid biopsies are minimally invasive and can detect cancer markers even before physical symptoms appear.
This process provides deep insights into cancer’s molecular profile, enabling doctors to understand which mutations are driving the disease and which treatments may be most effective. The integration of AI-powered analysis takes this technology a step further by processing vast amounts of genetic data to improve accuracy and detect cancer earlier.
How AI Enhances Liquid Biopsy for Lung and Breast Cancer
AI plays a crucial role in enhancing the power of liquid biopsy. AI algorithms can analyse large datasets from genetic tests, identifying patterns and mutations that might otherwise be overlooked by traditional methods. This combination of AI and liquid biopsy is showing promising results in detecting lung and breast cancer earlier and more accurately than ever before.
For instance, in lung cancer detection, AI can analyse circulating tumour DNA (ctDNA) to identify mutations such as EGFR and KRAS, which are often associated with specific subtypes of lung cancer. Early identification of these mutations allows doctors to select the best treatment options, including targeted therapies that are more effective and less harmful than traditional chemotherapy.
Similarly, in breast cancer, AI-powered liquid biopsies can detect BRCA mutations and other critical genetic markers, helping doctors assess whether a patient is at higher risk for developing breast cancer. This enables the recommendation of preventative measures, such as prophylactic surgeries or personalised therapies, based on the individual’s genetic profile.
The Advantages of AI-Powered Liquid Biopsy
Non-invasive
Unlike traditional tissue biopsies that require surgical procedures, liquid biopsies only need a simple blood sample. This makes the process significantly less invasive and more comfortable for patients.
Early Detection
Liquid biopsies can identify cancers at very early stages—often before symptoms appear. This allows for timely intervention and improves the chances of successful treatment. Early detection is key to better outcomes.
Personalised Treatment
AI-powered liquid biopsies help identify specific genetic mutations. This enables doctors to recommend targeted therapies based on each patient’s unique molecular profile, improving treatment effectiveness.
Continuous Monitoring
These biopsies allow for real-time monitoring of cancer progression and how the patient is responding to treatment. This supports timely adjustments in therapy, improving long-term care.
Cost-effective
AI enhances the speed and efficiency of liquid biopsy analysis. This reduces the time and cost compared to traditional diagnostic methods, making early screening more accessible to patients.
Real-World Impact: AI-Powered Liquid Biopsy in Action
AI-powered liquid biopsies are already making a significant impact in clinical settings:
In the UK, the NHS has begun using AI-powered liquid biopsies in clinical trials for breast cancer. These tests have demonstrated high levels of accuracy in detecting early-stage cancers, even in patients with no visible symptoms. This technology has the potential to improve survival rates by identifying cancers at an early stage and providing a more precise understanding of the disease.
In the U.S., AI-powered liquid biopsies for lung cancer are already in use. They are helping doctors detect critical genetic mutations like EGFR and KRAS, which play an important role in determining the most appropriate treatment options. These advancements are making lung cancer detection faster and more efficient, offering patients better treatment outcomes and saving lives.
The Future of AI-Powered Liquid Biopsy
The future of AI-powered liquid biopsy is incredibly promising, with ongoing research and development aimed at further enhancing its accuracy and expanding its scope. As AI algorithms continue to advance, we can expect even greater breakthroughs in early cancer detection.
In the near future, liquid biopsy could become a standard part of routine cancer screening, not only for lung and breast cancer but also for other types of cancer, offering a non-invasive and cost-effective solution for cancer detection. For a deeper look at how genetic testing is revolutionising early detection, read our detailed breakdown.
Furthermore, as more cancer-related genetic mutations are discovered, AI algorithms will continue to evolve, allowing for even more personalised treatment plans. In the future, AI-powered liquid biopsies could provide a comprehensive cancer screening tool, capable of detecting a wide range of cancers at their earliest and most treatable stages.

Frequently Asked Questions About AI-Powered Liquid Biopsy
1. How does an AI-powered liquid biopsy work?
An AI-powered liquid biopsy analyses circulating tumour DNA (ctDNA) from a simple blood sample. AI algorithms process vast amounts of genetic data to identify mutations and patterns linked to cancer, enabling earlier and more accurate detection—even before symptoms appear.
2. What cancers can AI-powered liquid biopsy detect?
Currently, AI-powered liquid biopsies are most commonly used for lung and breast cancer detection. However, the technology is advancing rapidly and may soon be used to detect colorectal, prostate, and ovarian cancers as well.
3. Is liquid biopsy better than traditional biopsies?
Yes. Liquid biopsy is non-invasive, requires only a blood sample, and can detect cancer at earlier stages—even before visible symptoms arise. In contrast, traditional biopsies are invasive, require tissue samples, and may miss early-stage detection.
4. Can AI-powered liquid biopsy replace traditional imaging methods?
AI-powered liquid biopsy provides significant advantages in early detection and continuous monitoring, but it is not a complete replacement for imaging methods. It works best when used alongside traditional imaging for a more accurate diagnosis and treatment plan.
5. Is AI-powered liquid biopsy covered by insurance?
Insurance coverage varies by region and provider. As this technology becomes more widely adopted, coverage is expected to improve. It’s best to consult with your healthcare provider or insurer to understand your eligibility for reimbursement.
