No mystery. No euphemisms. Here’s what actually happens.

Let’s deal with the part everybody thinks about first.
A prostate screening does not automatically mean a finger in your rectum.
For many men, prostate cancer screening begins with something much less dramatic: a PSA (prostate-specific antigen) blood test. PSA is a protein produced by cells in the prostate. The test measures how much of it is circulating in your blood and can help identify when your prostate may need a closer look.1
Depending on your age, risk factors and results, that may be the only test you need at that visit.
So if you’ve been putting off the conversation because of what you think a prostate screening involves, here’s the whole thing, step by step.
Step 1: You talk about your risk
Before anybody orders a test, your healthcare provider may ask about things like:
- Your age
- Your family history of prostate cancer
- Your race or ancestry
- Previous PSA results
- Other medical conditions
- Medications you’re taking
- Any urinary or prostate symptoms
Why?
Because prostate cancer risk isn’t the same for everyone, and neither is the decision about when to begin screening.
Step 2: You get a PSA blood test
The test itself is simple: a standard blood draw.
Your result comes back as a number measured in nanograms per milliliter (ng/mL).
A nanogram is one-billionth of a gram. So ng/mL simply tells you how much PSA is present in each milliliter of blood.
You don’t really need to remember the unit. The number and how it compares with your previous results are what matter.
And this next part matters too:
There isn’t one PSA number that means “cancer.”
Historically, a PSA above 4.0 ng/mL has often been considered elevated. But doctors don’t simply divide results into “safe” and “cancer.”
Age matters. Previous PSA results matter. Certain medications matter. And in general, the higher the PSA, the greater the likelihood that prostate cancer could be present. But there is no single cutoff that can tell for certain whether you do or don’t have prostate cancer.1
A PSA test doesn’t diagnose cancer. It tells your doctor whether your prostate may need a closer look.
Cancer is only one reason the number can rise.
A high PSA doesn’t mean you have prostate cancer. It means there’s something worth understanding.
Step 3: Maybe there’s a physical exam. Maybe there isn’t.
Here’s the part responsible for an extraordinary amount of anxiety about prostate screening.
The digital rectal exam, or DRE.
Yes, it involves a healthcare provider inserting a lubricated, gloved finger into your rectum to feel part of your prostate.2
There’s no point pretending otherwise.
But there’s also no reason to make it bigger than it is.
You’ll usually stand and bend forward or lie on your side. The exam itself generally takes only a short time. Your provider is feeling the prostate for changes in its size, shape or texture.
It can be uncomfortable.
It shouldn’t be a major ordeal.
And importantly, you may not need one at all.
Modern prostate cancer screening centers primarily on PSA testing. A DRE may also be used, but it isn’t as effective as PSA testing at detecting prostate cancer and isn’t necessarily part of every screening.2
In other words, the exam that keeps some men from talking about prostate screening may not even happen.
The myth has become considerably more intimidating than the screening itself.
So when should you get screened?
There isn’t one universally agreed-upon age at which every man should automatically begin prostate cancer screening.
The American Cancer Society recommends starting the conversation about screening at:3
Age 40
If you’re at the highest risk, including men with more than one first-degree relative who developed prostate cancer at an early age.
Age 45
If you’re at higher risk, including Black men and men with a father or brother diagnosed with prostate cancer before age 65.
Age 50
If you’re at average risk and expected to live at least another 10 years.
These aren’t automatic screening dates. They’re ages to start the conversation about whether screening makes sense for you.
Other medical organizations use somewhat different age ranges. The American Urological Association recommends offering screening beginning between ages 40 and 45 for people at increased risk, including those with Black ancestry, certain inherited genetic mutations or a strong family history.4
That’s why this isn’t really a question of memorizing one birthday.
It’s a conversation about your risk.
What does prostate health have to do with ED?
Your prostate and your erections aren’t separate from the rest of your health.
Prostate conditions can affect sexual function, and treatments for prostate cancer can sometimes affect the nerves and blood vessels involved in erections. At the same time, erectile dysfunction can be connected to other health factors, including blood flow, diabetes, medications, hormones and stress.
That doesn’t mean ED is a sign of prostate cancer. It means changes in your erections are worth talking about, too.
A prostate screening is a good opportunity to look at the bigger picture. If you’ve noticed changes in your erections, urinary habits or sexual function, tell your doctor. You don’t need to know whether they’re related. That’s what the conversation is for.
How often do you need a PSA test?
Not necessarily every year.
How often you’re screened can depend on your PSA result, age, health, family history and personal preferences.
For men who choose screening, the American Cancer Society says those with a PSA below 2.5 ng/mL may only need to be retested every two years. Men with a PSA of 2.5 ng/mL or higher should be screened annually.3
Your healthcare provider may recommend something different based on your individual risk.
The important point is that prostate screening isn’t automatically an annual conveyor belt of tests and exams.
What if your PSA comes back high?
First:
Don’t assume it’s cancer.
PSA can rise for reasons that have nothing to do with cancer, including:1
- An enlarged prostate (benign prostatic hyperplasia)
- Prostate inflammation or prostatitis
- A prostate infection
- Recent ejaculation
- Vigorous exercise such as cycling
- Certain recent prostate procedures
Some medications can also lower PSA and affect how the result is interpreted.1
So one elevated number generally isn’t the end of the story.
Your doctor may simply repeat the PSA test. The National Cancer Institute notes that repeating an abnormal PSA in six to eight weeks may be recommended to confirm the original finding.1
If it comes back down, that tells your doctor something.
If it remains elevated or continues rising, that tells them something too.
Screening isn’t looking for a diagnosis in one blood test. It’s looking for information that tells you whether to keep looking.
What happens if something still doesn’t look right?
An abnormal PSA does not automatically mean you’re headed straight for a biopsy.
Depending on your results and risk, your doctor may recommend:
Another PSA test
Sometimes watching the number over time is the appropriate next step.
An MRI
An MRI can help doctors identify suspicious areas in the prostate and determine whether a biopsy may be needed.1
A biopsy
If further testing suggests cancer could be present, a doctor may take small samples of prostate tissue to examine under a microscope. A biopsy is the test that can determine whether prostate cancer is present.1
And even then, finding prostate cancer doesn’t automatically mean immediate surgery or radiation.
Some prostate cancers grow so slowly that active surveillance — closely monitoring the cancer rather than immediately treating it — may be appropriate.
What if your doctor hasn’t mentioned screening?
You don’t need an elegant opening.
Try:
“I’m ___ years old. Should we be talking about prostate cancer screening?”
Or:
“Prostate cancer runs in my family. Should I have a PSA test?”
Or even:
“I’ve never had my PSA checked. Should I?”
That’s enough.
Your doctor can take it from there.
The prostate screening you imagined probably isn’t the one you’ll have
For years, prostate screening has been reduced to one joke about one uncomfortable exam.
That’s done men a disservice.
Today’s conversation is much more likely to begin with your personal risk and a simple blood test. If something looks unusual, the next step may be another blood test or an MRI before anyone starts talking about a biopsy.1
Screening has limitations. It can produce false alarms and sometimes detect cancers that would never have caused problems during a man’s lifetime. That’s why major medical organizations emphasize informed decision-making, rather than simply telling every man to get screened at the same age and frequency.3,4
But don’t let embarrassment make the decision for you.
Know your age.
Know your family history.
Know your risk.
And when it’s time, ask the question.
