IPM Take
This is not a breakthrough study because it discovered that exercise is good for health. It matters because it challenges one of the quiet assumptions that often sits behind prevention policy: that chronic disease somehow limits the preventive value of lifestyle interventions. Instead, the evidence suggests the opposite. Even among people already living with type 2 diabetes or cardiovascular disease, physical activity remains strongly associated with lower cancer risk. The science is increasingly clear. The policy question is why prevention still receives a fraction of the attention given to treatment.
Executive Summary
Researchers from the International Agency for Research on Cancer (IARC) and collaborators analysed data from nearly 600,000 adults across six European countries and found that higher levels of physical activity were associated with a lower risk of cancer, regardless of whether individuals had type 2 diabetes or cardiovascular disease. Published in Nature Communications Medicine, the study examined 15 physical activity-related cancers and found similar protective associations among participants with and without cardiometabolic disease. The findings strengthen the evidence base for integrated prevention strategies that target cancer, diabetes, obesity and cardiovascular disease through shared interventions.
Why it matters
- Policymakers: Supports a stronger case for integrated non-communicable disease prevention strategies rather than disease-specific programmes.
- Clinicians: Reinforces the importance of physical activity counselling even among patients already living with cardiometabolic conditions.
- Public authorities: Highlights an opportunity to align cancer prevention, obesity, diabetes and cardiovascular health programmes around common risk factors.
- Patients: Suggests that the benefits of physical activity extend beyond cardiovascular and metabolic health and may contribute to lower cancer risk even after chronic disease develops.
Health systems often organise prevention as separate conversations.
Cancer prevention sits in one policy document. Diabetes prevention sits in another. Cardiovascular disease sits somewhere else.
The biology is increasingly telling a different story.
The new IARC-led analysis examined almost 600,000 adults from the EPIC and UK Biobank cohorts and found that people who were more physically active experienced lower cancer risk, regardless of whether they were living with type 2 diabetes or cardiovascular disease.
Importantly, the study focused on physical activity outside the workplace, including recreational and household activity. Across 15 physical activity-related cancers, researchers found broadly similar protective associations among participants with and without cardiometabolic disease.
That matters because prevention policy is increasingly moving towards integrated management of non-communicable diseases.
Obesity, diabetes, cardiovascular disease and several cancers share many of the same upstream risk factors, including sedentary lifestyles, metabolic dysfunction and chronic inflammation. Yet health systems often continue to address these conditions through separate funding streams, separate programmes and separate political conversations.
The study does not prove causation, nor does it resolve ongoing debates about the optimal type or intensity of exercise. What it does provide is another large-scale signal that prevention benefits do not disappear once chronic disease is established.
For health systems facing rising rates of obesity, diabetes and cardiovascular disease, that message carries practical implications. Prevention cannot be viewed only as a tool for healthy populations. It may also remain relevant for millions of people already living with chronic disease.
For IPM, the broader lesson is that personalised prevention is becoming as important as personalised treatment.
The future burden of cancer and cardiometabolic disease may be shaped not only by new medicines and diagnostics, but by whether health systems can successfully implement evidence-based prevention at scale.
