Still getting routine checkups after 65? A geriatric doctor flags 5 tests most patients are never warned about — do you know which ones to refuse

The risk-to-benefit math changes dramatically after 70. Here is what the evidence says — and five questions that will change your next doctor’s appointment.

Picture this. You are 74 years old. You feel great. Sleeping well, decent energy, doing the things you enjoy. You go in for a routine physical. Nothing special. Your doctor glances at your chart and says — let’s run a few tests, just to be safe.

Six weeks later you are sitting in a surgeon’s office. Not because anything was wrong with you. But because those just-to-be-safe tests found something. And that something set off a chain of events your body at 74 was not equipped to handle.

That exact story plays out more often than the medical system likes to admit. The data behind it deserves a serious conversation. Because here is the truth that most doctors won’t say out loud in a 15-minute appointment: after the age of 70, some of the most common routine medical tests can cause more harm than good. Not because medicine is broken — but because the risk-to-benefit math changes dramatically as we age. And nobody is doing that math in the room with you. (Based on the insights of Dr. Franklin)

The Concept You Need First: The Longevity Lens

When you are 50, screening medicine works beautifully. You find a problem early, you treat it, and you potentially buy yourself 30 more years of healthy life. The math is clean. But after 70, three things change simultaneously — and understanding them changes everything.

First, many conditions detected by routine screening in older adults will never actually harm you. They grow slowly, cause no symptoms, and you will likely outlive them. But once they show up on a report, medicine does not have a “leave it alone and watch” button. It has a treatment button. And the treatment button gets pressed.

Second, your body’s tolerance for intervention drops with age. The surgery a 55-year-old bounces back from in two weeks can mean months of recovery, complications, and permanent loss of independence in a 78-year-old. The same procedure, very different outcomes.

Third — and this is the one most people never think about — there is something called the cascade effect. One test finds a small abnormality. That triggers a follow-up scan. The scan recommends a biopsy. The biopsy leads to a procedure. The procedure causes a complication. And suddenly a person who walked in feeling perfectly healthy is navigating a medical nightmare that began with a test they did not need.

Keep that lens in mind as we go through each of the five checkups.

Checkup 1: Routine Colonoscopy After Age 75

The United States Preventive Services Task Force — the gold standard body that sets screening guidelines — officially recommends against routine colonoscopy screening for average-risk adults over the age of 75. If you have no symptoms, no family history of colon cancer, and previous scopes came back clean, the risks begin to outweigh the rewards after that age. That is not a fringe opinion. It is the official guideline of the body that sets the standards for preventive medicine in the United States.

And those risks are real. Bowel perforation — a literal tear in the colon — occurs in approximately one in every 500 colonoscopies. In a younger adult, that is a manageable surgical complication. In a 77-year-old, it can mean emergency surgery, a colostomy bag, extended hospitalisation, and a recovery that fundamentally changes quality of life.

The bowel prep — the liquid drunk the night before to clear the colon — presents its own risk for older adults. Severe dehydration and dangerous electrolyte imbalances can develop before the procedure even begins. In adults with already reduced kidney function, the prep can hit hard enough to require emergency hospitalisation on its own.

Meanwhile, the colon cancers most likely to be found in asymptomatic older adults tend to grow so slowly that in many cases they would never cause problems within a person’s remaining lifetime. The detection does not help; the cascade that follows it can.

What to do instead: ask your doctor about non-invasive stool-based tests such as the Cologuard or annual FIT test. These can flag genuine warning signs without procedural risk. If you do have symptoms — blood in the stool, unexplained changes in bowel habits — that changes the equation entirely. Seek evaluation promptly.

Checkup 2: Aggressive PSA and Mammography Screening for Low-Risk Patients After 75

This topic deserves careful nuance. Cancer screening has saved millions of lives and absolutely can save yours. What changes after 75 is a specific problem called overdiagnosis — and overdiagnosis leads directly to overtreatment.

Imaging technology today is so sensitive that it can detect cancers that are biologically barely awake. Tiny, slow-growing tumours that, left alone, would never spread, never cause a symptom, and never shorten your life. You would die with them, not from them. But the moment a radiologist writes the word “malignancy” on a report, the clinical machine turns on — biopsies, specialist referrals, treatment decisions — regardless of whether the cancer actually poses a threat to you specifically.

Studies in the New England Journal of Medicine found that a substantial portion of cancers detected through mammography in women over 70 were clinically insignificant — meaning treatment offered no survival benefit, only side effects. For prostate cancer, multiple studies document men in their late 70s and 80s who underwent radiation or other treatment for slow-moving, low-grade prostate cancer and experienced significant reductions in quality of life — chronic fatigue, urinary problems, and more — from treatment they were unlikely to need.

What to do instead: have an honest conversation with your doctor about your specific risk profile. If you have a family history, genetic markers, or symptoms — screen. If you are average risk with no symptoms, ask your doctor directly: if we find something, what are the realistic treatment options at my age, and what would we actually recommend? That question alone often transforms the conversation from automatic screening to personalised decision-making.

Checkup 3: Routine Cardiac Stress Testing Without Symptoms

This one surprises people because it sounds so logical. You are 72. Your doctor says — let’s just make sure your heart is doing OK. You get on a treadmill or receive a medication that temporarily stresses the heart. Sounds responsible. Here is the problem.

Cardiac stress tests in people without symptoms have false positive rates that can reach 40% or higher in certain populations. That means nearly half the time, the test flags an abnormality when your heart is actually fine. But medicine cannot simply shrug at an abnormal finding. That false alarm launches a cardiac catheterisation — threading a thin tube through your blood vessels directly into your heart. Risks include bleeding, vessel damage, arrhythmia, and in rare cases, triggering the very heart attack or stroke you were trying to prevent.

And here is where it becomes even more counterintuitive. If the catheterisation finds a partial blockage — extremely common in adults over 70 who have zero symptoms — you may end up with a cardiac stent. Multiple landmark clinical trials, including the widely cited ISCHEMIA trial, found that stenting in patients with stable coronary artery disease did not reduce heart attacks or extend life compared to medication and lifestyle management alone.

The stent carried real procedural risks plus a lifetime of blood thinners with their own bleeding complications — for no additional statistical benefit over the alternative of medication and a daily walk. The cascade produced a worse outcome than doing less would have.

What to do instead: if you have no chest pain, no unexplained shortness of breath, and no dizziness during activity, discuss optimising your modifiable risk factors with your doctor — blood pressure, cholesterol, blood sugar, activity level, sleep quality. That is where the most meaningful gains are, and the evidence supports it more strongly than routine stress testing in asymptomatic older adults.

Checkup 4: Routine DEXA Bone Density Screening With Automatic Medication

Osteoporosis is real and falls are devastating in older adults. This is not in dispute. What is worth questioning is the automatic pipeline that often follows a DEXA scan result in patients over 75 — specifically, the routine prescription of bisphosphonate medications without a full discussion of the alternatives and the risks.

Long-term bisphosphonate use — medications like alendronate or risedronate — has been associated with a rare but serious condition called atypical femoral fractures: spontaneous stress fractures in the thigh bone, the very bone the medication was intended to protect. These fractures can be severe and require surgery. These medications are also linked to osteonecrosis of the jaw — bone deterioration that is painful and notoriously difficult to treat.

Meanwhile, the most effective intervention for preventing fractures in older adults — by a significant margin — is not a medication. It is fall prevention. Balance training. Studies show Tai Chi specifically reduces fall risk by nearly 50%. Removing tripping hazards from the home, installing grab bars, reviewing medications for those that cause dizziness, ensuring adequate protein and vitamin D in the diet — these interventions reduce fracture risk more meaningfully than bisphosphonates with zero associated side effects.

There are absolutely patients who need bone-protective medication — those who have already had fractures, those with very low T-scores, those with specific medical risk factors. But a routine DEXA leading automatically to long-term medication in an active 74-year-old who has never broken a bone and is otherwise healthy is a conversation worth having, not a foregone conclusion.

What to ask before accepting medication: can we review my specific fall risk factors first, and what is the actual fracture risk reduction from this medication compared to a structured fall prevention programme?

Checkup 5: Asymptomatic Carotid Artery Ultrasound Screening

This is the one almost nobody is talking about — and based on what the research shows, it may be the most quietly consequential test on this list. Most people have never heard of it until it directly affects them.

A carotid artery ultrasound checks the large blood vessels in your neck that carry blood to your brain. The idea sounds logical: if we find a significant blockage, we can surgically clean it out and reduce your stroke risk. The reality is far more complicated — and for asymptomatic patients, far more dangerous than it sounds.

The surgical procedure used to treat a carotid blockage — called a carotid endarterectomy — carries a 2 to 3% risk of causing a stroke during or immediately after the procedure. In older adults with other health conditions, that risk is higher. The United States Preventive Services Task Force explicitly recommends against routine carotid artery screening in adults who have no symptoms, no mini-strokes, no vision loss episodes, no neurological events. Their analysis found that in asymptomatic people, the risk of surgical harm outweighs the benefit.

Here is why. Many people over 70 have some degree of narrowing in their carotid arteries. That narrowing has often been there for years — stable, silent, causing no problems. When you screen for it routinely, you find it. And then a well-meaning surgeon recommends fixing it. But the surgery to fix a blockage that was never causing symptoms can and sometimes does dislodge a tiny piece of plaque that travels directly to the brain. The procedure intended to prevent a stroke can cause one.

What to do instead: focus on the actual modifiable stroke risk factors. Blood pressure is the single biggest driver of stroke — managing it aggressively is more protective than surgical intervention on an asymptomatic carotid narrowing. Add blood sugar control, smoking cessation, atrial fibrillation management, and regular physical activity. If you do experience any neurological symptoms — even brief ones that resolved completely, sudden vision changes, facial drooping, arm weakness, sudden severe headache — seek evaluation immediately. Symptomatic disease is an entirely different situation.

The Five Questions to Bring to Every Appointment After 65

These five questions can change the dynamic of any medical appointment. Write them down. Keep them in your phone. Bring them every time a screening test is recommended.

Question 1: What is the false positive rate of this test in people my age? This tells you how likely the test is to trigger unnecessary follow-up procedures even if nothing is actually wrong.

Question 2: If this test finds something, what are the realistic treatment options for someone my age and health status? This forces the conversation toward outcomes, not just findings.

Question 3: What is the procedural risk of any treatment we would likely pursue? Every procedure carries risk. You deserve to know it before the cascade begins, not after.

Question 4: What happens if we monitor this instead of treating it? For many conditions found in older adults, watchful waiting with regular monitoring is a legitimate and often superior option that may never come up unless you ask.

Question 5: What is the most effective non-invasive intervention for this condition? Because very often — as with bone health, heart health, and stroke prevention — lifestyle and medication outperform procedural intervention with far less risk and far fewer side effects.

Any good physician will welcome these questions. They will respect you more for asking them. If your doctor dismisses these questions or makes you feel difficult for raising them, that is important information about whether that relationship is working in your best interest.

The Bigger Picture

There is a meaningful difference between medicine that finds things and medicine that helps you live well. After 70, the goal of your healthcare should not be to generate findings. It should be to protect and extend your quality of life — your independence, your energy, your ability to do what matters to you.

The best physicians understand that doing less sometimes takes more wisdom than doing more. That recommending watchful waiting requires more courage than ordering another scan. You have the right to know what a test is looking for, what happens if something is found, and whether a finding would actually be treated in a way that genuinely improves your life. The five questions above are the tools that give you that right in practice.

Frequently Asked Questions

My doctor recommended one of these tests — should I refuse it?

No — the goal is not to refuse tests but to have an informed conversation before agreeing to them. Ask the five questions in this article. If your doctor explains the specific reasoning for why your individual risk profile makes the test appropriate in your case, that context changes the picture. What the evidence argues against is routine, automatic screening in average-risk asymptomatic older adults — not medically indicated testing for specific individual circumstances. Your doctor knows your history; use these questions to make sure the decision is personalised, not just protocol-driven.

What is the cascade effect and how do I avoid it?

The cascade effect is the chain of interventions triggered by an initial test finding — each step generating more risk than the one before. A routine test finds a small abnormality. That triggers a follow-up scan. The scan recommends a biopsy. The biopsy leads to a procedure. The procedure causes a complication. It can be avoided by asking Question 2 and Question 3 from the five-question protocol before the first test — specifically, “if this finds something, what would we actually do about it?” If the answer involves a sequence of increasingly invasive procedures for a finding that might never cause symptoms, that is important information to have before the cascade starts rather than after.

Are there screening tests that ARE still recommended after 70?

Yes, several. Blood pressure monitoring remains critically important at any age — it is the single biggest modifiable stroke risk factor. Blood sugar testing for diabetes management continues to be valuable. Vision and hearing checks, which directly affect fall risk and cognitive health, are strongly recommended. Skin checks for suspicious lesions in people with significant sun exposure history are still appropriate. Vaccinations — including flu, pneumonia, shingles, and COVID — are among the highest-value health interventions available for adults over 65. The argument here is not against all preventive medicine. It is against specific procedural screening where the evidence shows risk exceeds benefit in asymptomatic older adults.

What symptoms should always prompt immediate evaluation regardless of age?

Several symptoms change the picture entirely and warrant same-day or emergency evaluation regardless of the general screening guidance above: blood in the stool or urine; chest pain or pressure during activity; unexplained shortness of breath that is new or worsening; any neurological symptoms including sudden vision changes, facial drooping, arm weakness, sudden severe headache, or speech difficulty — even brief ones that resolved; unexplained significant weight loss; a lump that has appeared or grown in the past few weeks; and any symptom that is new, persistent, and unexplained. The guidance in this article is specifically about asymptomatic routine screening. Symptoms are a different conversation entirely.
