Antiaging Interventions: The Forefront of Cancer Chemoprevention

In 2015, President Obama’s State of the Union address highlighted the Precision Medicine Initiative, which seemed to renew the concept of cancer prevention as a form of preemptive medicine (predicting the onset of disease and taking preventive measures in advance to prevent or delay the onset of disease). However, this concept has actually been around for a long time. Cancer prevention strategies are basically divided into two categories: the “population strategy,” which assumes that a large number of people carry a small but potential risk, and the “high-risk strategy,” which takes into account the existence of a small number of individuals with high risk. The former is the foundation of traditional cancer prevention policies such as primary and secondary prevention, while the latter is a strategy close to “diagnosis and treatment” in hospitals and can be considered an aggressive measure in line with personalized medicine.
