Visit cervical cancer screening is one of the most effective preventive tools available: it helps detect changes in cervical cells long before cancer develops. Behind this screening lies a link that has become central in recent years—the link between the human papillomavirus (HPV) and cervical cancer. This article explains this link, the difference between the Pap test and the HPV test, at what age and how often screening is generally recommended, as well as the role of vaccination and prevention. All of this is presented in clear, respectful language that is inclusive of everyone with a cervix.

The Link Between HPV and Cervical Cancer
Visit human papillomavirus (HPV) is a very common infection that is transmitted through sexual contact, including skin-to-skin contact in the genital area. It is estimated that about 80 % of sexually active people will contract HPV at some point in their lives. In the vast majority of cases, the body clears the virus on its own, without any symptoms appearing.
The problem arises when an infection with certain types of HPV—known as «high-risk» types—persists over time. Over several years, this persistence can lead to changes in the cells of the cervix, known as precancerous lesions. If left undetected, some of these lesions can progress to cancer. It is precisely this long period of progression that makes screening so valuable: it allows time to identify and treat abnormalities before cancer develops.
An often silent and ancient virus
- Most HPV infections do not cause any symptoms.
- The virus can remain dormant for 15 to 20 years without affecting one's health.
- A positive result may therefore reflect an exposure that occurred many years ago.
- Anyone with a cervix who has ever been sexually active may be at risk.
Pap Test or HPV Test: What's the Difference?
People often confuse the Pap test and the HPV test, since the sample is collected in the same way. The difference lies in what the laboratory is looking for in the sample.
The Pap Test
The Pap test (or Papanicolaou test) examines cells collected from the cervix to detect any abnormalities that are already present. This approach has been used for decades and has led to a significant reduction in cervical cancer mortality.
The HPV Test
The HPV test looks for the presence of the high-risk virus itself, even before the cells have changed. Because it targets the cause rather than the consequence, it is considered more accurate at detecting the risk of precancerous lesions, which allows for longer intervals between screenings.
| Element | Pap Smear | HPV Test |
|---|---|---|
| What he's looking for | Abnormal cells in the cervix | High-Risk Presence of the Virus |
| Target Age Group | Ages 21 to 65 | Ages 25 to 65 |
| Usual frequency | Every 2 to 3 years | Every 5 years |
| Withholding | Cervical cells collected with a brush | Cervical cells collected with a brush |
General guidelines. The actual test and time frame depend on your region, your situation, and your healthcare provider’s advice.
To remember
- HPV is a very common infection and is usually asymptomatic.
- Certain types of high-risk HPV, if they persist, can lead to cervical cancer.
- Screening is designed to detect abnormalities before cancer develops.
- The Pap test looks for abnormal cells; the HPV test looks for the virus.
- The HPV test is more accurate at detecting the risk of precancerous lesions.
- Screening is recommended for anyone with a cervix.

The Ongoing Transition in Quebec
Quebec is in the process of changing its approach to cervical cancer screening: the HPV test is gradually replacing the Pap test as the primary test, or «first-line test.» This change was recommended by INESSS and is based on data showing that the HPV test is more effective at detecting risk early.
What's Changing
- The age at which screening begins is now 25 with the HPV test.
- The HPV test is generally performed every five years, rather than every two to three years.
- The age at which screening ends remains 65.
A phased rollout
The transition to HPV testing is taking place gradually, depending on the region and the laboratory. The Pap test may therefore still be offered in some areas until the HPV test is fully implemented there. Specifically, if you’ve had a Pap test recently, it’s not recommended that you undergo HPV screening right away: your healthcare provider will advise you on the best time based on your medical history and where you live.
At what age and how often
The issue of the’age and frequency This is a common topic, as it has changed with the introduction of the HPV test. Here are the general guidelines in Quebec.
Why Start at Age 25?
Among people under 25, HPV infections are common but are usually temporary: the body clears them on its own. At this age, cervical cancer is also very rare. Screening too early could therefore do more harm than good, leading to unnecessary tests and treatments, as well as stress and anxiety. That is why HPV testing begins at age 25.
General Guidelines
- HPV Test: Ages 25 to 65; generally every five years if the result is negative.
- Pap test (where it is still the primary screening method): ages 21 to 65, every two to three years.
- People with weakened immune systems may follow a different schedule, to be determined in consultation with their doctor.
- HPV vaccination is not a substitute for screening: the two complement each other.
These are general guidelines. Your personal situation, medical history, and the availability of tests in your area may affect this timeline. Your healthcare provider will work with you to determine the most appropriate course of action.
How the exam is conducted and the results
Visit withholding is the same for both tests and takes only a few minutes. It is performed by a healthcare professional in an environment that respects your comfort and privacy.
Tax Withholding at a Glance
- The healthcare provider gently inserts a speculum to get a clear view of the cervix.
- Using a small brush, he gently scrapes the surface of the cervix to collect cells.
- The cells are placed in a liquid and sent to the laboratory.
- The same sample can be used for both the HPV test and a follow-up cell analysis, if necessary.
Understanding the Results
A negative result means that no abnormalities requiring special follow-up were detected; the next screening is generally recommended in five years using the HPV test. A positive result does not mean you have cancer: it indicates the presence of HPV and, in some cases, cells that need to be monitored, and leads to further testing or close follow-up, depending on the individual.
| Results | What that means | As usual |
|---|---|---|
| Negative | No issues to monitor at this time | A new screening is recommended at a later date, depending on the interval |
| Positive | Presence of HPV; in some cases, cells that require monitoring | Additional tests or close monitoring |
| Invalid | Nonconforming sample | The test may need to be repeated |
A test result is not a diagnosis. It is up to your healthcare provider to interpret it.
HPV vaccination
Visit HPV vaccination is another pillar of prevention. It protects against the types of viruses most commonly responsible for cervical cancer, as well as other cancers and certain genital warts. It works to prevent future infections; it does not treat an existing infection.
What You Need to Know
- The vaccine is available to children and adults, in accordance with current recommendations.
- In Quebec, it is offered free of charge as part of an elementary school curriculum.
- It protects against several types of HPV associated with cancer of the cervix, vagina, vulva, anus, and head and neck.
- Since it does not cover all types of HPV, it is not a substitute for screening.
Vaccination and screening complement each other: the vaccine reduces the risk of infection, and screening allows for the early detection of abnormalities in people who have already been exposed. A vaccinated person should therefore still participate in cervical screening as recommended.
Signs to Watch for Despite Screening
Screening is intended for people who have no symptoms. But some signs warrant seeking medical attention immediately, rather than waiting for the next screening, as they may have several underlying causes that need to be evaluated.
- Unusual vaginal bleeding, especially after sexual intercourse or between periods.
- Bleeding after menopause.
- Abnormal or persistent vaginal discharge.
- Persistent pelvic pain or pain during sexual intercourse.
These signs do not mean that it is cancer—far from it. They simply indicate that an evaluation is advisable. If you notice them, talk to a healthcare professional rather than waiting.
Myths and misconceptions
«A positive HPV test means I have cancer.»
False. A positive result simply indicates the presence of the virus, which is very common. It leads to follow-up care or additional tests, not to a cancer diagnosis.
«I've been vaccinated, so I don't need to get tested anymore.»
False. The vaccine does not protect against all types of HPV. Screening is still recommended even for vaccinated individuals.
«If I don't have any symptoms, there's no point in getting tested.»
False. Screening is specifically designed for people without symptoms. Precancerous lesions generally do not cause any symptoms, which is why it is important to detect them early.
«HPV affects only women.»
Nuanced. HPV affects anyone who is sexually active and can cause other types of cancer in people of all genders. Cervical screening, on the other hand, is for anyone with a cervix.
«The HPV test is more painful than the Pap test.»
False. The sample collection procedure is the same for both tests. Only the laboratory analysis differs.
Frequently asked questions
Is a cervical screening painful?
The procedure takes a few minutes and mainly causes a sensation of pressure or mild, temporary discomfort. Feel free to discuss this with your healthcare provider, who can adjust their approach to make you feel more comfortable.
Should I get a Pap test or an HPV test?
It depends on where you live, as the HPV test is being rolled out gradually in Quebec. Your healthcare provider will let you know which test is available and the best time to have it based on your medical history.
How often should I get screened?
If your HPV test is negative, screening is generally done every five years; with a Pap test, every two to three years. The frequency may vary depending on your situation and should be determined in consultation with your healthcare provider.
What happens if my test result is positive?
A positive result does not mean a diagnosis of cancer. It leads to follow-up care or additional tests to clarify the situation. The healthcare professional tailors the choice of tests to each individual.
Should screening continue after age 65?
The age at which screening typically ends is 65, provided you have a history of adequate screening. Your healthcare provider will confirm whether or not you can stop screening.
Can we discuss screening during an online consultation?
Yes. A remote consultation can help assess your situation, answer your questions, and guide the screening process that will take place in person later, since the sample itself is collected on-site.
