Most people approaching retirement spend months running the numbers. They model Social Security claiming strategies, stress-test their portfolios, and debate whether to work one more year. What far fewer pre-retirees do is gather the single piece of information that quietly shapes every one of those decisions: an honest, detailed assessment of their own health.
The math of retirement rests on an assumption almost nobody says out loud, how long you will live, and how many of those years will be healthy ones. Retire at 62 in good health, and you may have three vigorous decades to fund. Retire with an undetected condition and the picture, both personal and financial, looks very different.
Health is also the largest wild card in a retirement budget. Fidelity estimates that a 65-year-old retiring in 2025 will spend an average of $172,500 on health care over the course of retirement, and that figure has climbed more than 4% in a single year. Those costs are not evenly spread. A serious diagnosis caught late can mean years of expensive treatment; the same condition caught early is often cheaper to treat and less likely to force an unplanned exit from the workforce.
Knowing where you actually stand lets you make the big calls with real information instead of optimism. It can tell you whether to keep working a few more years while you feel strong, whether to retire sooner and enjoy good health while you have it, and how aggressively to plan for future medical costs.
For decades, a thorough physical meant bloodwork and a handful of age-based tests. A new category of preventive screening goes considerably further, and it has become far more accessible in the past two years.
The best-known name is Prenuvo, which offers a whole-body MRI that scans from head to toe in about an hour, with no radiation, contrast dye, or needles. A single scan can flag early signs of cancers in organs like the liver, kidneys, and pancreas, as well as aneurysms, spinal problems, and metabolic markers such as visceral and liver fat. Prenuvo says roughly 1 in 20 people who come in have a finding that their clinical team considers potentially significant. The company has been adding FDA-cleared, AI-assisted tools to its platform to constantly improve accuracy and detection. A full-body scan runs about $2,500-$3500 and is generally not covered by insurance. I recently had one done myself so I can speak directly to the experience. The process was quick and easy, and yes, I was stressing about the results until they came back a few weeks later. As they say, knowing is half the battle, so I think it’s better to know than not.
Competition has pushed the price down quickly. In 2025, Function Health, a membership service built around comprehensive lab testing launched a full-body scan for around $499, a fraction of what these scans cost a few years ago. Hospital systems have long offered "executive physical" programs as well, bundling advanced imaging, cardiac testing, and specialist consults into a day or two of appointments. The common thread is a shift from waiting for symptoms to actively looking for problems while they are small and fixable.
Comprehensive screening is genuinely useful, but it is not a magic wand, so the first step should absolutely be to discuss this with your doctor. Whole-body scans are prone to incidental findings. Depending on the study, somewhere between 30% and 40% of healthy people will show something that warrants a follow-up, and the large majority of those turn out to be harmless. That can mean additional testing, out-of-pocket cost, and real anxiety over what is ultimately nothing. These scans also miss some things a targeted test would catch, which is why they complement, rather than replace, guideline-based screenings like colonoscopies and mammograms. And because insurance rarely pays, the cost comes straight out of pocket.
None of this is a reason to avoid screening. It is a reason to go in with clear expectations and to review the results with your doctor who knows your history.
The point of a screening in the years before retirement is not to chase certainty, but rather it is to trade a large unknown for better information right when the stakes are highest. A clean, reassuring result can give you the confidence to retire on the schedule you want. An early finding, caught while you are still working and insured, may be the most valuable thing you learn all year both medically and financially. Either way, the results feed directly into the decisions that matter most: when to stop working, how much to set aside for health care, whether to accelerate certain plans, and how to think about insurance and long-term care.
Retirement planning has always been about managing uncertainty. A comprehensive health screening simply removes one of the biggest uncertainties from the equation, and these days, it is easier and more affordable to do than ever.
Frequently Asked Questions About Health Screenings
1. Should I get a health screening before I retire?
Yes. Your health can significantly impact your retirement timeline, lifestyle, and financial needs. A comprehensive health screening may uncover conditions early, giving you more information to make confident decisions about when to retire and how to plan for future healthcare costs.
2. What is a full-body MRI screening?
A full-body MRI is a preventive scan that examines your body from head to toe without radiation or needles. It can help identify certain health concerns, such as cancers, aneurysms, spinal issues, and metabolic markers before symptoms appear. However, it should complement, not replace, routine screenings recommended by your physician.
3. How does my health affect my retirement plan?
Your health influences more than just medical expenses; it can affect how long you work, when you claim retirement benefits, how much you should save, and your long-term care planning. Having a clearer understanding of your health can help you make retirement decisions with greater confidence.
