Knowing which types of care you can safely skip might actually improve your health and could save you money and time.
Ever wonder if every medical test or treatment you’ve taken was truly necessary? Or are you inclined to get every bit of health care you can? Maybe you feel good about getting the most out of your health insurance. Perhaps a neighborhood imaging center is advertising discounted screening tests, your employer offers health screens as a perk, or you’re intrigued by ads touting supplements for a seemingly endless number of conditions.
But keep in mind: just because you could get a particular test or treatment or take a supplement doesn’t mean you should. One study suggests that as much as 20% of all health care in the US is unneeded. In short: when it comes to health care, more is not always better.
Isn’t it Better to Be Proactive About Your Health?
We’re all taught that knowledge is power. So it might seem reasonable to want to know as much as possible about how your body is working. And isn’t it better to take action before there’s a problem rather than waiting for one to develop? What’s the harm of erring on the side of more rather than less?
The truth is that knowledge is not always power: if the information is irrelevant to your specific situation, redundant, or inaccurate, the knowledge gained through unnecessary health care can be unhelpful or even harmful. Unnecessary tests, treatments, and supplements come with risks, even when they seem harmless. And, of course, unnecessary care is not free — even if you’re not paying a cent out of pocket, it drives up costs across health systems.
Screening Tests, Wellness Strategies, and Treatments to Reconsider
Recommended screening tests, treatments, and supplements can be essential to good health. But when risks of harm outweigh benefits — or if proof of any benefit is lacking — think twice. Save your time, money, and effort for health care that is focused on the most important health threats and backed by evidence.
Cancer Screening: When to Stop?
Screening tests for some cancers are routinely recommended and can be lifesaving. But there’s a reason they come with a recommended stop age. For instance, guidelines recommend that a person at average risk of colorectal cancer with previously normal colonoscopies stop having them once they turn 75. Similar limits apply to Pap smears (age 65) and mammograms (age 75). Studies suggest that beyond those ages, there is little benefit to continuing these screens.
Watch Out for Wellness Marketing
Dietary supplements are a multibillion-dollar industry. And a whopping 70% or more of US adults take at least one, such as vitamin D, fish oil, or a multivitamin. People often consider them as insurance in case vital elements are missing from their diet, or they believe supplements can prevent dementia, heart disease, or another condition.
Yet little evidence supports a benefit of routine supplement use for everyone. While recent studies suggest a daily multivitamin might slow cognitive decline in older adults, there’s no medical consensus that everyone should be taking a multivitamin. Fish oil (omega-3) supplements haven’t proven to be as healthful as simply eating servings of fatty fish and other seafood low in toxic chemicals like mercury and PCBs. And the benefits of routinely taking vitamin D supplements remain unproven as well.
It’s worth emphasizing that dietary supplements clearly provide significant benefit for some people and may be recommended by your doctor accordingly. For example, if you have a vitamin or mineral deficiency or a condition like age-related macular degeneration, good evidence supports taking specific supplements.
Reconsider Daily Aspirin
Who should be taking low-dose aspirin regularly? Recommendations have changed in recent years, so this is worth revisiting with your health care team.
Older recommendations favored daily low-dose aspirin to help prevent cardiovascular disease, including first instances of heart attack and stroke.
New recommendations favor low-dose aspirin for people who’ve already experienced a heart attack, stroke, or other cardiovascular disease. Adults ages 40 to 59 who are at a high risk for these conditions and low risk for bleeding also may consider it.
Yet according to a recent study, nearly one-third of adults 60 and older without past cardiovascular disease take aspirin, despite evidence that it provides little benefit for those at average or low risk. Aspirin can cause stomach bleeding and raise risk for a certain type of stroke.
Weigh In on Prostate Cancer Screening
Men hear about prostate cancer often. It’s common, and the second leading cause of cancer deaths among men. But PSA blood tests and rectal exams to identify evidence of cancer in the prostate are no longer routinely recommended for men ages 55 to 69 by the United States Preventative Services Task Force.
The reason? Studies suggest that performing these tests does not reliably reduce suffering or prolong life. Nor do possible benefits offset downsides like false positives (test results that are abnormal despite the absence of cancer). That can lead to additional testing, some of which is invasive.
Current guidelines suggest making a shared decision with your doctor about whether to have PSA testing after reviewing the pros and cons. For men over age 70, no screening is recommended. Despite this, millions of men have PSA tests and rectal examinations routinely.
Not Everyone Needs Heart Tests
There are now more ways than ever to evaluate the health of your heart. But none are routinely recommended if you’re at low risk and have no signs or symptoms of cardiovascular disease. That’s right: in the absence of symptoms or a high risk of cardiovascular disease, it’s generally safe to skip EKGs, stress tests, and other cardiac tests.
Yet many people have these tests as part of their routine care. Why is this a problem? Having these tests without a compelling reason comes with risks, especially false positive results that can lead to invasive testing and unneeded treatment.
Four More Reasons to Avoid Unnecessary Care
Besides the concerns mentioned already, there are other reasons to avoid unnecessary care, including:
- The discomfort or complications of testing: If you’re needle-phobic, getting a blood test is a big deal. And while complications of noninvasive testing are rare (such as a skin infection from a blood test), they can occur.
- The anxiety associated with waiting to find out test results: The stress and anxiety of waiting for results can negatively impact your mental health.
- False reassurance that comes with false negatives: Results that are normal or nearly so might suggest no disease when disease is actually present, leading to false reassurance.
- All treatments have side effects: Even minor reactions — like occasional nausea or constipation — seem unacceptable if there’s no reason to expect benefit from treatment.
The Bottom Line
You may believe your doctor wants you to continue with your current schedule of tests and treatments, while they might think this is your preference! It’s worth discussing if you haven’t already, especially if you suspect you may be taking pills or getting tests you don’t truly need.
If your doctor says you can safely skip certain tests, treatments, and supplements, it doesn’t mean that he or she is neglecting your health or that you don’t deserve great health care! It’s likely that the balance of risks and benefits simply doesn’t support doing these things.
Less unnecessary care could free up resources for those who need it most. And it could save you time, money, and unnecessary risks or side effects, thus improving your health. It’s a good example of how less can truly be more.
