Why Preventive Healthcare Happens Before Something Feels Wrong
10/7/26 | Valerie S. | 5 min. read
"I feel fine."
We hear that a lot.
And frankly?
We hope you do.
You don't have pain.
You're going to work.
You're exercising.
You're traveling.
You're keeping up with your family.
Nothing feels particularly wrong.
So why would you have a preventive scan?
Because there's something important to understand about preventive healthcare:
Feeling fine is exactly when prevention is supposed to happen.
We're Used to Going to the Doctor When Something Hurts
For most of our lives, healthcare has followed a pretty familiar pattern.
Something hurts.
Something changes.
Something doesn't feel right.
So we call the doctor.
And that's exactly what we should do when symptoms develop.
But that's reactive healthcare.
Preventive healthcare asks a different question:
What can we learn before something feels wrong?
That's the philosophy behind many of the screenings we already accept as a normal part of healthcare.
Mammograms aren't reserved for women who already feel a lump.
Colon cancer screening isn't only for people who already have symptoms.
Blood pressure is checked before someone has a stroke.
Cholesterol is monitored before someone has a heart attack.
And for people who meet established eligibility criteria, low-dose CT lung screening is performed specifically to look for lung cancer in people who may have no symptoms at all.
The whole idea is to look earlier.
Because Your Body Doesn't Always Send an Early Warning
We'd like to think our bodies will tell us when something is wrong.
Sometimes they do.
But sometimes they don't.
Coronary artery disease can develop for years before someone experiences obvious symptoms.
Certain cancers can grow without causing noticeable symptoms early in the disease.
Some abnormalities are discovered incidentally while physicians are looking for something completely different.
The absence of symptoms is good news.
But it isn't a guarantee.
"I feel fine" and "nothing is happening inside my body" aren't necessarily the same statement.
Your Heart Is a Perfect Example
Someone can exercise.
Feel healthy.
Go about everyday life.
And still have plaque developing in the coronary arteries.
A coronary artery calcium scan uses CT imaging to look for calcified plaque in those arteries.
That's information you can't feel.
You can't look in the mirror and see it.
And a routine physical examination can't directly show it.
The scan doesn't replace your physician or your bloodwork.
It provides another kind of information.
It lets us look.
This Isn't About Searching for Bad News
This distinction matters.
Preventive healthcare should not turn healthy people into frightened people.
You shouldn't wake up every morning wondering what disease might be hiding inside you.
That's not what we're advocating.
We're talking about making thoughtful healthcare decisions based on things like:
Your age.
Your family history.
Your personal medical history.
Your lifestyle.
Your risk factors.
And conversations with your healthcare provider.
Sometimes those conversations lead to screening.
Sometimes they don't.
The goal isn't to test for everything imaginable.
The goal is to make informed decisions about what's appropriate for you.
And Sometimes the Result Is...
Nothing.
No concerning finding.
No unexpected abnormality requiring additional evaluation.
Just reassuring information.
We don't talk about that outcome nearly enough.
Preventive imaging isn't valuable only when it discovers a problem.
There can also be value in learning that a particular scan didn't identify something concerning at that moment.
That doesn't guarantee tomorrow.
No medical test can do that.
But information doesn't have to be bad news to be valuable.
"But Wouldn't I Know If Something Were Wrong?"
Not always.
That's really the point.
If every serious disease produced obvious symptoms at its earliest and most treatable stage, preventive screening would be far less important.
But medicine knows that's not how every disease behaves.
Sometimes symptoms are the first clue.
Sometimes family history is the clue.
Sometimes bloodwork is the clue.
And sometimes...
the first clue is a picture.
Prevention Happens While Life Is Happening
Maybe this is the part we should think about differently.
Preventive healthcare doesn't happen because you're sick.
It happens while you're busy being well.
You're working.
Planning vacations.
Going to dinner.
Walking the dog.
Watching your kids or grandchildren grow up.
Living all of those wonderfully ordinary Tuesdays we've talked about before.
The purpose of prevention isn't to interrupt that life with fear.
It's to help protect as much of it as possible.
Take the First Step
If you feel great today, we're glad.
Keep seeing your physician.
Keep getting your recommended screenings.
Keep paying attention to your health.
Know your family history.
Understand your individual risk factors.
And talk with your healthcare provider about whether additional screening or imaging is appropriate for you.
Being proactive doesn't mean expecting something to be wrong.
It means understanding that sometimes the best opportunity to learn something about your health...is before your body has to tell you.
