What is HPV? A guide for people starting from zero
HPV (human papillomavirus) is a very common family of viruses with more than 200 types. Most sexually active people come into contact with it at some point in their lives. Most infections cause no symptoms and clear on their own; only some high-risk types can lead to cell changes, and only if they persist for a long time. This process is slow, can be screened for and is largely preventable. A positive HPV result calls for proper follow-up, not panic.
This page is written for someone who is hearing about HPV for the first time or knows nothing about it. Medical terms are explained where they first appear.
What exactly is HPV?
HPV stands for human papillomavirus. It is not a single virus but a large family of more than 200 related viruses. Members of this family behave differently: some cause common warts on the hands or feet, some cause warts in the genital area, and a small group ("high-risk types") is linked to certain cancers over the long term.
Think of HPV as a "virus family" with many members. Most members are harmless and clear on their own; only a few types need follow-up, and only if they persist.
A quick look at HPV types
HPV types are referred to by numbers (HPV 6, 16, 18…) and fall roughly into two groups: low-risk types (especially 6 and 11) are mostly linked to genital warts; high-risk types (especially 16 and 18) are linked to certain cancers if they persist. Which type is found in your test result affects the follow-up decision.
How common is HPV?
HPV is the most common sexually transmitted infection. It is so common that most sexually active people come into contact with at least one HPV type at some point in their lives. Often this goes completely unnoticed, because…
A healthy immune system usually clears the majority of HPV infections on its own within this time.
So coming into contact with HPV does not mean "something bad has happened to me." For most people, it is a temporary situation that the body quietly takes care of.
How does it spread?
HPV most often spreads through skin-to-skin contact, especially during sexual contact. Transmission does not require a sore or any symptoms; a person carrying the virus often does not even know it.
- It can spread through vaginal, anal and oral contact.
- Condoms lower the risk but do not remove it completely, because skin areas they don't cover can still come into contact.
- It is often impossible to tell when the virus was acquired; it may have been years ago.
That last point matters: a positive HPV result is not a sign of infidelity or a reason for blame. Because the virus can stay silent for years, a positive result cannot be taken as evidence about a relationship.
Does it cause symptoms?
Most of the time, no. Most HPV infections cause no symptoms at all and pass unnoticed. When symptoms do appear, they usually take one of two forms:
- Genital warts: Small, mostly painless bumps caused by low-risk types (6, 11).
- Cell changes: Changes that high-risk types can cause in the cervix. They cannot be seen with the naked eye and are found only through screening tests.
This is why screening is so important: early changes in the cervix cause almost no symptoms. Not feeling anything does not mean a checkup is unnecessary.
Does every HPV infection cause cancer?
No. This is the most common misconception. Most infections clear on their own and cause no problems. Cancer risk only comes into play if the following chain is completed:
- A high-risk type is acquired,
- the infection is not cleared and persists for years,
- over time it causes cell changes (precancerous lesions),
- and if these changes are not detected and treated, they can progress to cancer over a long period.
Note that this process usually takes years, often more than a decade. This slowness is our biggest advantage — regular screening gives a chance to break the chain while it is still at the precancerous stage.
HPV and cervical cancer
High-risk HPV is the main cause of cervical cancer. But HPV is not limited to the cervix; persistent high-risk infection is also linked to some cancers of the vagina, vulva, anus and the mouth and throat.
We mention this not to frighten you but to show why screening and vaccination are so valuable: cervical cancer is one of the few cancers that can be largely prevented with regular screening and vaccination.
Prevention: vaccine and screening
There are two main tools, and they complement each other:
- Vaccine: Protects against the HPV types that most often cause disease. It works best when given before contact with the virus (at a young age); however, eligibility at any age is assessed separately with a doctor.
- Screening: The Pap test (smear) and HPV-DNA test pick up changes early, before they cause symptoms. Screening is recommended even if you have been vaccinated, because the vaccine does not cover all types.
In Türkiye, the Ministry of Health offers women aged 30–65 free HPV-DNA screening every five years at family health centers, community health centers and KETEMs (Cancer Early Diagnosis, Screening and Training Centers). Ask your doctor about eligibility and frequency.
What to do if you test HPV positive
A positive HPV result on its own is not a cancer diagnosis. It only shows that an HPV type is present in your body. What happens next is decided by looking at which type it is, your Pap test result, your age and your previous tests together.
- Does your result list the HPV type (for example, 16/18)? Make a note of it.
- Do you have a Pap test result from the same period?
- Your doctor will decide whether further evaluation, such as colposcopy, is needed.
A single positive result is not the whole basis for a treatment decision. The right step is to continue follow-up with a doctor who looks at all your results together.
When should you see a doctor?
These are usually not emergencies, but they should be checked in good time:
- if your Pap test or HPV test showed an abnormal / positive result,
- if you notice a new wart, bump or change in the genital area,
- if you have bleeding after sex, bleeding between periods or unusual discharge,
- if you are of screening age and have not had a checkup in a long time.
These symptoms are often due to benign causes unrelated to HPV — but the only way to be sure is to have them evaluated.
Frequently asked questions
Does HPV only spread through sexual intercourse?
Sexual contact is the most common route, but skin-to-skin contact can be enough. Transmission does not require symptoms or a visible sore.
Does HPV go away on its own?
The immune system clears most infections, usually within 1–2 years. High-risk types that persist need follow-up.
Does a positive HPV test mean I have cancer?
No. A positive result only shows that the virus is present. Cancer risk comes from a high-risk type persisting for years and causing cell changes — and from those changes not being monitored. The process is slow and can be screened for.
My result shows HPV 16 or 18. What does that mean?
These two types are high-risk and are the types most often linked to cervical cancer. A positive result for them does not mean cancer; your doctor will decide whether closer follow-up or further evaluation is needed.
If I've had the vaccine, do I still need screening?
Yes. The vaccine covers the most common types but not all of them, so vaccinated people continue with the recommended screening program.
Can men get HPV?
Yes. HPV also occurs in men and can cause genital warts and some cancers. A general HPV screening test is not routinely recommended for men; if there are symptoms, they should see the relevant specialist (urology/dermatology).
Does a positive HPV result mean my partner was unfaithful?
No. Because the virus can stay silent for years, it is often impossible to tell when or from whom it was acquired. A positive result should not be read as grounds for blame.
Do condoms protect against HPV?
They lower the risk considerably but do not remove it completely, because skin areas not covered by the condom can still come into contact. Using them is still recommended.
Is HPV screening free in Türkiye?
In Türkiye, the Ministry of Health offers free HPV-DNA screening every five years to women aged 30–65. Ask your doctor or, in Türkiye, your family health center whether you are eligible.
