TL;DR
Eric Topol argues that 2026 will mark the start of precision medical forecasting, using large-scale data and models to predict individual risk for major age-related diseases. He links these conditions—cancer, cardiovascular, and neurodegenerative disorders—to long preclinical phases and shared immune-aging processes, suggesting earlier interventions could be possible.
What happened
In a Wired piece published Dec. 23, 2025, Eric Topol contends that 2026 will usher in an era of precision medical forecasting. Drawing an analogy to recent improvements in weather prediction driven by large language models, Topol envisions similar advances applied to individual health risk assessments. The focus is on major age-related illnesses—cancer, cardiovascular disease, and neurodegeneration—which often develop silently over many years. Topol emphasizes common biological features underlying these disorders, specifically the decline in immune competence and increased chronic inflammation, described respectively as immunosenescence and inflammaging. By detecting risk patterns well before symptoms arise, he argues, clinicians could implement preventive measures far earlier in a person’s disease trajectory. The article links this shift to broader changes in data-driven medicine but does not provide detailed implementation timelines or specific clinical tools.
Why it matters
- Earlier and more individualized risk predictions could enable preventive actions long before symptoms appear.
- Targeting shared biological mechanisms—immune decline and chronic inflammation—offers a unified approach to multiple age-related diseases.
- A move from reactive treatment to proactive forecasting could change clinical decision making and public-health planning.
Key facts
- Author Eric Topol is founder and director of the Scripps Research Translational Institute and wrote the article for Wired.
- Topol predicts 2026 will mark the start of precision medical forecasting.
- He compares potential advances in medical risk prediction to improvements in weather forecasting powered by large language models.
- The article highlights three major age-related disease categories: cancer, cardiovascular disease, and neurodegenerative disorders.
- Topol notes these illnesses often have long incubation phases before symptoms emerge, commonly spanning two decades or more.
- He identifies immunosenescence (age-related immune decline) and inflammaging (heightened chronic inflammation) as shared biological underpinnings.
- The piece emphasizes the potential for data and models to permit earlier preventative measures, but stops short of detailing specific technologies or trials.

Quick glossary
- Precision medical forecasting: Using detailed individual data and predictive models to estimate a person’s future risk of disease and guide preventive care.
- Immunosenescence: The gradual decline in immune system function that can occur with aging.
- Inflammaging: A state of chronic, low-grade inflammation associated with aging that contributes to disease risk.
- Large language model (LLM): A type of artificial intelligence trained on large text datasets to generate or analyze language and, increasingly, to help model complex patterns in other data domains.
- Incubation phase (in chronic disease): A prolonged period during which underlying disease processes develop without producing overt symptoms.
