The Gap Between Intention and Action
Most adults understand, in principle, that preventive screenings matter. Yet year after year, large numbers of eligible adults remain overdue for at least one recommended test. The reasons people cite are consistent: cost, time, fear, or simply feeling too healthy to bother. What the evidence shows is that these reasons — while understandable — rarely hold up to scrutiny.
This article examines the most common barriers adults report, and what current evidence actually says about each of them. If you are new to thinking about preventive care more broadly, our foundational guide to preventive health is a good place to begin.
~72%
Adults who skip at least one recommended screening
CDC data consistently shows a substantial proportion of eligible adults are not up to date on recommended preventive screenings, with rates varying by screening type and demographic group.

Colorectal cancers potentially preventable with screening
The American Cancer Society estimates that the majority of colorectal cancer deaths could be prevented or reduced through timely screening and removal of precancerous polyps.

U.S. adults with undiagnosed prediabetes
According to the CDC, approximately 96 million American adults have prediabetes, and more than 80% are unaware of their status — making blood glucose screening especially important.
Common Myths — and What the Evidence Says
The misconceptions below represent the most frequently cited reasons adults delay or avoid screenings. Each pairs the common belief with what the medical evidence actually supports.
Myth
I feel fine, so I don't need to be screened for anything right now.
Fact
Many serious health conditions — including high blood pressure, prediabetes, and some cancers — produce no symptoms in early stages.
The absence of symptoms is not the same as the absence of disease. Conditions like hypertension are sometimes called "silent" precisely because they progress without obvious warning signs. Preventive screenings exist to find these problems early, when treatment options are typically broader and outcomes generally better. Feeling healthy is a good sign — but it is not a diagnostic tool.
Myth
Screenings are expensive and probably not worth the cost.
Fact
Under the Affordable Care Act (ACA), most recommended preventive screenings are covered at no cost-sharing when provided by an in-network provider.
Many adults assume preventive care comes with a significant bill, but federal law requires most health insurance plans to cover USPSTF A- and B-rated screenings, as well as certain vaccines and counseling services, without copays or deductibles. For those without insurance, community health centers, federally qualified health centers, and state programs often offer screenings at reduced or no cost. It is worth verifying your specific coverage with your insurer, but cost is far less of a barrier than many people assume.
Myth
Screenings are painful and invasive — I'd rather avoid the discomfort.
Fact
Most routine screenings involve minimal discomfort, and many are non-invasive blood tests, questionnaires, or brief physical assessments.
Concern about discomfort is understandable, but it often stems from unfamiliarity or exaggerated expectations. A cholesterol panel, blood pressure check, or skin exam involves little to no discomfort. Even procedures that do involve some degree of discomfort — such as a colonoscopy — are typically performed with sedation, and the temporary experience is generally considered manageable by most people who undergo them. Talking through specific concerns with your provider in advance can also help manage anxiety. See our guide to making the most of your appointment for practical strategies.
Myth
Screenings are only important once you're older.
Fact
Several screenings are recommended beginning in young adulthood, including checks for blood pressure, cholesterol, cervical cancer, sexually transmitted infections, and mental health.
Age-based assumptions cause many adults in their 20s and 30s to skip screenings entirely. In reality, screening schedules are calibrated to age and risk, with some starting earlier than people expect. For a full reference by life stage, see screening tests by age. Establishing a screening baseline early also makes it easier to detect meaningful changes over time.
Myth
If there were a problem, my doctor would have already told me.
Fact
Providers can only screen for conditions they have an opportunity to assess — and many adults do not have annual wellness visits.
Preventive screenings are typically conducted at dedicated wellness visits, not urgent care appointments or sick visits. If you primarily see a provider only when ill, you may be missing the structured check-ins where screenings are ordered and reviewed. Additionally, individual risk factors — including family history — affect which screenings a provider will recommend. Being proactive about scheduling a wellness visit and discussing your personal history gives your care team the full picture they need. Starting with the basics of preventive care can help you understand what to ask for.
Myth
I eat well and exercise, so screenings don't really apply to me.
Fact
Healthy lifestyle habits reduce risk but do not eliminate it — genetics, environmental exposures, and other factors remain relevant regardless of lifestyle.
A nutritious diet and regular physical activity are genuinely protective — but they are not a guarantee against disease. Certain conditions have strong hereditary components, and others arise from factors entirely outside lifestyle control. Health-conscious adults are sometimes the most likely to rationalize skipping screenings, assuming their habits make them low-risk. As explored in screenings often overlooked by health-conscious adults, this group has its own blind spots worth addressing.
Don't Wait for Symptoms to Appear
One of the defining features of conditions like hypertension, type 2 diabetes, and several cancers is that they often cause no noticeable symptoms in their early stages. Waiting until something feels wrong can mean missing the window when intervention is most effective. Routine screenings are specifically designed to catch these conditions before symptoms develop.
What Happens When Screenings Are Skipped
Delaying a screening does not delay the underlying condition — it delays detection. In many cases, that delay matters clinically. Early-stage findings are often more treatable, less costly to address, and less disruptive to daily life than late-stage diagnoses. This is not a guarantee of any specific outcome, but the pattern holds broadly across conditions for which screening is established.
It is also worth recognizing that screenings have genuine trade-offs — false positives, follow-up procedures, and psychological stress are real. A balanced look at preventive care's benefits and limitations can help you make a more informed decision in conversation with your provider.
