Does preventive healthcare actually save money in the long run, or is that just an assumption we repeat? I've seen my insurance premiums rise even as I get free annual checkups, and studies on screening programs are mixed. For example, some cancer screenings lead to overdiagnosis and unnecessary treatment. If I'm paying more now to avoid costs later, but the later costs are often covered by public funds anyway, what's the real incentive? Could the system shift to more lifestyle-based interventions that are harder to measure?
