Beyond the Heart: Should We Be Screening for Cancer Before Symptoms Develop?

Cardiovascular disease has become increasingly predictable and preventable through advances in coronary imaging and metabolic medicine, but as heart risk becomes more manageable, cancer remains the major threat to healthspan that medicine has been slowest to intercept early. Multi-cancer early detection blood tests and prostate-specific antigen screening share many of the same philosophical tensions as preventive cardiology — promising earlier intervention but carrying real risks of overdiagnosis and anxiety. This article explains the evidence behind these emerging tools, their limitations, and why a cardiovascular clinic has found itself at the centre of a broader conversation about proactive health.

From Cardiovascular Prevention to a Broader View of Health

The patient sitting in front of me had no symptoms. He was fifty-four, a non-smoker, with a total cholesterol that his GP had declared entirely satisfactory and a blood pressure that hovered just below the threshold for treatment. By every conventional metric, he was fine. A coronary CT scan told a different story: significant plaque burden in his left anterior descending artery, and a fat attenuation index measurement that placed him in a high-risk category for a cardiovascular event within the next decade. ¹ He left that appointment on a statin, an antihypertensive, and with a clear plan. He also left asking a question I now hear regularly: if we can find heart disease before it causes symptoms, why can't we do the same for cancer?

It is a reasonable question, and one that has fundamentally shaped how Surrey Cardiovascular Clinic has evolved. SCVC, working with its imaging partner Virtual Cath Lab, became an early adopter of advanced coronary CT imaging and is now one of the UK's major independent providers of this technology. Central to our preventive programme is the Fat Attenuation Index, or FAI — a technique developed at Oxford and commercialised by Caristo Diagnostics. FAI uses the information already contained within a standard coronary CT scan to assess inflammation in the pericardial adipose tissue, the fat that wraps around the coronary arteries. Inflamed fat is less dense than stable fat, and that difference in density is detectable on CT and quantifiable. ² Think of it as reading the temperature of the tissue surrounding the vessel wall, using the CT as a thermometer. The landmark CRISP-CT study, published in The Lancet in 2018, demonstrated that elevated FAI was associated with significantly increased cardiovascular mortality over the following five years. ² The ORFAN study, published in The Lancet in 2024, extended and strengthened that association in a larger population, establishing FAI as a clinically meaningful prognostic tool rather than a research curiosity.

This imaging capability sits within a broader preventive architecture. Our programmes incorporate advanced lipid testing — including ApoB, lipoprotein(a), and non-HDL cholesterol — alongside fasting insulin, glucose tolerance assessment, wearable continuous glucose monitoring, and CT quantification of visceral adipose tissue. Treatment is correspondingly sophisticated, combining intensive LDL-lowering to guideline-recommended targets ³ with dietary and structured exercise interventions, and GLP-1 receptor agonists where metabolic criteria are met. The central message, which I believe the evidence now supports firmly, is that cardiovascular disease is increasingly predictable, manageable, and in many cases preventable. That realisation changes the clinical landscape — and it naturally raises the question of what other major threats to long-term health might be amenable to the same philosophy.

The Case for Multi-Cancer Early Detection — and Its Limits

Visceral obesity and insulin resistance do not confine their harm to the cardiovascular system. ⁴ The same metabolic milieu that accelerates coronary atherosclerosis is also associated with an increased risk of several cancers, including colorectal, pancreatic, and endometrial malignancies. When you are already measuring a patient's visceral adipose tissue on CT and fitting them with a continuous glucose monitor, the conversation about cancer risk arises naturally. It was this overlap in risk profile, as much as any commercial consideration, that led SCVC to introduce the Galleri multi-cancer early detection blood test as an optional component of its proactive health screening programme.

Galleri, developed by GRAIL, detects fragments of cell-free DNA shed into the bloodstream by tumour cells. What makes it distinctive is not merely that it detects cancer-associated DNA, but that it uses methylation patterns — chemical tags on the DNA that vary between tissue types — to predict where in the body a signal is coming from. The analogy I use with patients is that every cell in the body carries the same genetic code, but each cell type reads different chapters. Methylation is the bookmarking system. When cancer develops, those bookmarks are disrupted in characteristic ways, and Galleri is trained to recognise those patterns across more than fifty cancer types, the majority of which have no current NHS screening programme. ^5,6

The PATHFINDER 2 study, presented in 2023, reported encouraging results in a higher-risk population, with a positive predictive value — that is, the proportion of positive tests that correspond to a genuine cancer — of approximately forty percent. That figure sounds modest until you appreciate that most positive screening tests in medicine carry far lower predictive values when used in unselected populations. However, the NHS-Galleri trial, which enrolled approximately one hundred and forty thousand participants in a randomised design, published interim results that were more sobering. The detection rate for cancers in the screened arm was meaningful, but the trial was not powered to demonstrate a reduction in cancer mortality within its initial reporting period, and the NHS concluded that the evidence was not yet sufficient to support population-wide adoption. ⁷

This is not a reason to dismiss Galleri. It is a reason to counsel patients honestly. A negative result does not exclude cancer — the test's sensitivity across all cancer types and stages, particularly stage one disease, remains incomplete. ⁵ A positive result requires urgent but measured investigation, not panic. The test is best offered to individuals who understand these limitations, who are already engaged in a broader programme of health optimisation, and who would wish to act on an early signal if one were found. For those patients, appropriately counselled, the test adds information that no other currently available tool provides. The NHS's caution reflects the legitimate concerns of population-wide health economics and the risk of harm at scale from false positives. ⁸ It does not negate the potential value of the test in an informed, motivated individual who has sought it out for themselves.

Men's Health, Prostate Cancer, and the PSA Dilemma

The clinical overlap I see most consistently in practice is in men in their mid-forties to mid-sixties who present with a constellation of findings that no single specialty has traditionally owned: visceral obesity, borderline testosterone levels, insulin resistance, erectile dysfunction, and a vague awareness that their energy and drive have declined. These findings matter individually; together, they matter more. Erectile dysfunction in a man of fifty with no prior cardiac history is not simply a quality-of-life issue — it is frequently an early marker of endothelial dysfunction, the same process of impaired blood vessel responsiveness that precedes clinically apparent coronary artery disease. In practice, I treat a presentation of erectile dysfunction in a middle-aged man with cardiovascular risk factors as a prompt for thorough cardiac assessment, not a referral to urology.

This recognition led SCVC to establish its Men's Health Initiative, a structured clinic that addresses this cluster of interconnected issues under one roof. Cardiovascular assessment, metabolic profiling, testosterone evaluation, and lifestyle intervention are integrated rather than parcelled out across multiple specialties. Within this framework, we also offer informed discussion of PSA testing for prostate cancer.

PSA — prostate-specific antigen — is a protein produced by prostate tissue, and elevated levels in the blood can indicate prostate cancer, though they can also reflect benign enlargement, inflammation, or recent physical activity. The NHS does not currently operate a national prostate cancer screening programme. The reasons are important to understand: the major European randomised trial, ERSPC, showed a significant reduction in prostate cancer mortality with PSA screening, but at the cost of substantial overdiagnosis — meaning cancers detected and treated that would never have caused symptoms or shortened life. ⁹ The PIVOT trial complicated the picture further by showing that for many low-risk prostate cancers, radical treatment offered no survival advantage over active surveillance. Anxiety, unnecessary biopsy, and treatment complications including incontinence and erectile dysfunction represent real harms at population scale. ⁸

What has changed the calculus somewhat is the widespread adoption of multiparametric prostate MRI and the PI-RADS scoring system, which stratifies MRI findings from one (very low suspicion) to five (very high suspicion). An abnormal PSA result now typically leads to MRI before biopsy, substantially reducing the number of men who undergo unnecessary invasive investigation. This pathway improvement does not resolve the overdiagnosis problem, but it reduces the immediate procedural harm associated with a false-positive PSA. For men who understand this landscape and wish to be tested, an informed decision-making conversation — of the kind mandated by Montgomery consent principles — is entirely appropriate. The NHS's position on PSA screening reflects the difficulty of rolling this out equitably and safely at population scale. It does not mean that an informed individual should be denied the opportunity to decide for himself.

Key Takeaways

1
The Fat Attenuation Index, derived from coronary CT imaging and validated in the CRISP-CT and ORFAN Lancet studies, adds prognostic information about coronary inflammation that conventional risk scores do not capture, and is already available in specialist preventive cardiology programmes.
2
The Galleri multi-cancer early detection test shows meaningful promise in appropriately selected patients, but a negative result does not exclude cancer, and any positive result requires careful clinical interpretation rather than immediate alarm — honest pre-test counselling is essential.
3
Erectile dysfunction in a middle-aged man with cardiovascular risk factors should prompt proactive cardiac assessment, not solely urological referral, because it frequently reflects early endothelial dysfunction that predates overt coronary disease.
4
PSA testing for prostate cancer remains outside NHS population screening because of overdiagnosis risk, but the improved diagnostic pathway offered by multiparametric MRI and PI-RADS scoring means that an informed man requesting PSA discussion deserves a structured, evidence-based conversation rather than a blanket refusal.

# AI Companion Pack — Beyond the Heart: Should We Be Screening for Cancer Before Symptoms Develop? Author: Dr Edward Leatham · Channel: SCVC Blog · VTEF v1 · 2026-11-02 > Confidence scale: 🟢 established · 🔵 strong · 🟡 moderate · 🟠 emerging · 🔴 hypothesis. > A hypothesis is the author's own model, not established fact. Where guidelines differ, both sides are given. Educational content, not personal medical advice. ## Executive summary Cardiovascular medicine has become increasingly adept at detecting and intercepting disease before symptoms arise, using tools such as coronary CT imaging and the Fat Attenuation Index (FAI) to identify high-risk patients who would otherwise be reassured by conventional metrics. As this predictive capability matures, clinicians working in preventive cardiology are confronting a parallel challenge: cancer remains the major threat to healthspan that medicine intercepts latest. The metabolic conditions that drive coronary atherosclerosis — visceral adiposity, insulin resistance, and chronic inflammation — overlap substantially with the risk profiles for several common cancers, making the preventive cardiology consultation a natural setting for broader oncological conversation. Two screening technologies are examined here. The Galleri multi-cancer early detection (MCED) test analyses methylation patterns in circulating cell-free DNA to identify signals from more than fifty cancer types, the majority of which lack established screening programmes. Its promise is real, but so are its limitations: sensitivity is imperfect, a negative result does not exclude cancer, and positive results require careful clinical navigation. PSA testing for prostate cancer carries analogous tensions — it can identify disease early, but overdiagnosis and overtreatment remain genuine harms that the improved multiparametric MRI pathway partially mitigates. Erectile dysfunction in middle-aged men with metabolic risk factors is reframed not as a urological issue in isolation but as an early marker of endothelial dysfunction and a prompt for thorough cardiovascular assessment. Surrey Cardiovascular Clinic's Men's Health Initiative integrates these interconnected domains under one roof, reflecting an evolution from organ-specific cardiology towards whole-person proactive health. ## Key messages - Conventional risk metrics such as total cholesterol and blood pressure thresholds can normalise patients who carry significant subclinical coronary plaque burden; advanced CT-derived tools including plaque quantification and the Fat Attenuation Index reveal risk that standard scores miss. - The metabolic environment underpinning cardiovascular disease — visceral adiposity, insulin resistance, and systemic inflammation — is also associated with elevated risk for colorectal, pancreatic, endometrial, and other cancers, making metabolic medicine the connective tissue between cardiac and oncological prevention. - The Galleri MCED test detects methylation-based cancer signals across more than fifty tumour types; it is a promising adjunct in appropriately counselled patients but does not replace organ-specific screening and carries meaningful false-negative and false-positive rates. - PSA testing is not currently recommended as an NHS population screen because of overdiagnosis risk, but the availability of multiparametric MRI with PI-RADS scoring has improved the diagnostic pathway sufficiently that an informed man requesting discussion deserves a structured, evidence-based conversation. - Erectile dysfunction in a middle-aged man with cardiovascular risk factors should be treated as a potential early marker of endothelial dysfunction and a prompt for proactive cardiac assessment, not solely a urological referral. - Preventive cardiology clinics, by virtue of their metabolic focus and established imaging infrastructure, are well positioned to anchor broader proactive health programmes that address cancer and men's health alongside cardiovascular risk. ## Claim confidence table | Claim | Confidence | |---|---| | Plaque burden predicts ischaemic risk better than stenosis alone | 🟢 established | | FAI identifies coronary inflammation and predicts residual cardiovascular risk | 🔵 strong | | Statin and antihypertensive therapy reduce cardiovascular events in high-risk patients | 🟢 established | | Obesity is a leading avoidable cause of premature death | 🟢 established | | Galleri MCED test can detect cancer signals across more than fifty cancer types using methylation patterns | 🔵 strong | | Cell-free DNA fragmentation profiling can distinguish cancer from non-cancer | 🔵 strong | | Early cancer detection improves survival outcomes | 🟡 moderate | | Overdiagnosis is a quantifiable harm in cancer screening | 🟢 established | | PSA screening reduces prostate cancer mortality but carries overdiagnosis risk | 🔵 strong | | Visceral adiposity and insulin resistance increase cancer risk (colorectal, pancreatic, endometrial) | 🟡 moderate | | Erectile dysfunction in men with metabolic risk factors is a marker of endothelial dysfunction and an indicator for cardiac assessment | 🟡 moderate | | Multiparametric MRI and PI-RADS scoring mitigate overdiagnosis risk in PSA-positive men | 🔵 strong | | A negative Galleri result does not exclude cancer | 🟢 established | ## Evidence map | Statement | Classification | Evidence note | |---|---|---| | Plaque burden is a stronger predictor of ischaemic events than stenosis severity alone | 🟢 established | Mortensen et al., JACC 2020 (Ref 1);

Optimising all four forms the foundation of the preventive cardiovascular programme. **Q: What is the Fat Attenuation Index (FAI) and why does it matter?** FAI is a technique developed at Oxford and commercialised by Caristo Diagnostics. It analyses information already present in a standard coronary CT scan to assess inflammation in the pericardial fat surrounding the coronary arteries. Validated in the CRISP-CT and ORFAN Lancet studies, it adds prognostic information about coronary inflammation that conventional risk scores do not capture. **Q: Can someone with a normal cholesterol level and acceptable blood pressure still be at high cardiovascular risk?** Yes. The article describes a patient whose conventional metrics were unremarkable, yet coronary CT imaging revealed significant plaque burden and a high-risk FAI result. Standard thresholds can miss meaningful underlying disease. **Q: Why is visceral adipose tissue relevant to cancer risk as well as heart disease?** Visceral obesity and insulin resistance create a metabolic environment that promotes both coronary atherosclerosis and several cancers, including colorectal, pancreatic, and endometrial malignancies. Because VAT is already measured during CT imaging, cancer risk naturally enters the clinical conversation. **Q: What is the Galleri test and how does it work?** Galleri, developed by GRAIL, is a multi-cancer early detection blood test that identifies fragments of cell-free DNA shed by tumour cells. It uses methylation patterns — chemical tags that differ between tissue types — to detect signals across more than fifty cancer types and predict where in the body a signal originates. **Q: Does a negative Galleri result mean a patient is cancer-free?** No. A negative result does not exclude cancer. Honest pre-test counselling is essential so that patients understand the test's limitations before proceeding. **Q: What should a patient do if their Galleri result is positive?** A positive result requires careful clinical interpretation rather than immediate alarm. It should prompt structured follow-up investigation, not a panicked response, which is why informed pre-test discussion is so important. **Q: Why does erectile dysfunction in a middle-aged man prompt cardiac assessment at SCVC?** Erectile dysfunction frequently reflects early endothelial dysfunction — impaired blood vessel responsiveness — which is the same underlying process that precedes clinically apparent coronary artery disease. In a man of fifty with cardiovascular risk factors, it is treated as a prompt for thorough cardiac assessment, not solely a urological referral. **Q: What is the SCVC Men's Health Initiative?** It is a structured clinic that integrates cardiovascular assessment, metabolic profiling, testosterone evaluation, and lifestyle intervention under one roof, addressing the cluster of findings — including visceral obesity, insulin resistance, borderline testosterone, and erectile dysfunction — that no single specialty has traditionally owned. **Q: Why is PSA testing not part of NHS population screening?** The principal concern is overdiagnosis — detecting prostate cancers that may never cause harm but whose diagnosis leads to treatment with significant side effects. The risk-benefit balance at a population level has not met the threshold for a national programme. **Q: Has anything improved the PSA pathway enough to make testing worth discussing?** Yes. The availability of multiparametric MRI and PI-RADS scoring means that men with a raised PSA can be investigated more precisely before biopsy, reducing unnecessary intervention. An informed man requesting a PSA discussion now deserves a structured, evidence-based conversation rather than a blanket refusal. **Q: How does insulin resistance connect the four pillars to broader cancer and men's health risk?** Insulin resistance sits within the glucose/insulin pillar but has downstream effects across all four pillars — raising blood pressure, worsening lipid profiles, promoting VAT accumulation, and creating the metabolic milieu linked to both accelerated atherosclerosis and increased cancer risk. **Q: Why is a cardiovascular clinic involved in cancer screening conversations at all?** Because the risk profiles overlap substantially. Patients already attending for coronary CT imaging and metabolic profiling often carry the same visceral obesity and insulin resistance that elevates cancer risk. The infrastructure, patient relationship, and longitudinal monitoring required for proactive cancer detection are a natural extension of preventive cardiovascular care. **Q: What is the key message for patients considering any of these proactive screening tests?** Early detection offers genuine benefit, but every test carries the possibility of false positives, overdiagnosis, and anxiety. Informed, pre-test counselling that honestly explains both the promise and the limitations is as important as the test result itself. ## Reference library The complete reference list carried by the article.
