Most women with HPV have no symptoms at all. Between 70% and 90% of HPV infections are completely asymptomatic, which means the most reliable way to know if you have it is through screening tests, not by looking for signs on your body. Your immune system clears about 90% of infections on its own, often within two years, without you ever knowing the virus was there.
That said, there are some visible signs, specific tests, and screening timelines worth understanding so you can stay ahead of any problems.
Why Most Infections Go Unnoticed
HPV is not one virus but a large family of over 200 related types. Most of them quietly infect skin or mucous membrane cells and never cause anything you’d notice. Your immune system recognizes the virus, mounts a response, and eliminates it. This process can take months to a couple of years, and during that entire time you’d feel perfectly fine. You can also pass HPV to a partner even without any signs or symptoms, which is one reason the virus is so widespread.
The infections that do cause problems fall into two broad categories: low-risk types that can cause genital warts, and high-risk types that can, over many years, lead to cell changes and eventually cancer. There are 12 high-risk types, and two of them (types 16 and 18) are responsible for most HPV-related cancers. Virtually all cervical cancer is caused by HPV. But even high-risk infections usually clear on their own. It’s the ones that persist for years without being caught that pose the real danger, which is exactly why screening matters so much.
Visible Signs You Might Notice
The one physical clue HPV can leave is genital warts. These usually appear as a small bump or group of bumps in the genital area. They’re flesh-colored and can be flat or have a bumpy, cauliflower-like texture. In women, warts typically show up in or around the vagina, on the cervix, or around the anus.
Warts are caused by low-risk HPV types (most commonly types 6 and 11), which are different from the high-risk types linked to cancer. So having warts doesn’t mean you’re at higher risk for cervical cancer, and not having warts doesn’t mean you’re free of HPV. The high-risk strains that can lead to cancer almost never produce any visible changes you could spot on your own.
HPV can also infect the throat. Oropharyngeal infections sometimes cause a long-lasting sore throat, earaches, hoarseness, swollen lymph nodes, pain when swallowing, or unexplained weight loss. These cancers develop years after infection and are uncommon in women compared to men, but the symptoms are worth being aware of.
How HPV Is Actually Detected
Because the virus rarely announces itself, testing is the primary way women find out they have HPV. There are two main tests, and they’re collected the same way: a clinician inserts a speculum and uses a soft brush to gather cells from the surface of your cervix. The difference is what happens in the lab.
A Pap test (Pap smear) examines those cells under a microscope, looking for any that appear abnormal. It doesn’t test for HPV directly. Instead, it catches the cell changes that HPV can cause over time. Think of it as looking for the damage rather than the virus itself.
An HPV test looks for the DNA of the virus in those same cervical cells. It can tell you not just whether HPV is present but which type you have, which helps determine your level of risk. Both tests can be done from the same sample at the same visit, a process called co-testing.
One newer option: the FDA has approved two HPV tests that allow you to collect your own vaginal sample using a swab or brush, rather than having a clinician do it. For now, this self-collection still has to happen in a health care setting (a doctor’s office, urgent care, pharmacy, or mobile clinic), but it removes the need for a pelvic exam. Trials are underway to see whether home-based collection works just as well, with the goal of eventually making true at-home testing available.
When and How Often to Get Screened
Screening recommendations are based on your age, because the likelihood of a persistent infection and the usefulness of different tests change over time.
- Ages 21 to 29: Start Pap tests at age 21. If results are normal, you can wait three years before your next one. HPV testing alone isn’t recommended in this age group because HPV infections are extremely common in younger women and almost always clear on their own. Testing for the virus would flag too many infections that will never cause a problem.
- Ages 30 to 65: You have three options. An HPV test alone (called primary HPV testing) every five years, co-testing with both an HPV test and a Pap test every five years, or a Pap test alone every three years.
- Over 65: You can typically stop screening if you’ve had at least three normal Pap tests or two normal HPV tests in the past 10 years, with the most recent within the past few years, and no history of precancerous cervical changes.
There is no approved HPV screening test for men. If you’re wondering whether a male partner should get tested, current guidelines don’t recommend it. HPV tests for men simply aren’t available in routine clinical settings.
What Happens After an Abnormal Result
A positive HPV test or an abnormal Pap result doesn’t mean you have cancer. It means further evaluation is needed to see what’s actually going on with your cervical cells.
The most common next step is a colposcopy. During this procedure, a clinician uses a speculum and then applies a vinegar solution to your cervix, which makes abnormal areas temporarily turn white so they’re easier to see. An instrument with a bright light and magnifying lens is positioned outside your body to give a close-up view. If any areas look concerning, a small tissue sample (biopsy) is taken and sent to a lab. The whole process takes about 15 to 20 minutes.
What happens after that depends on what the biopsy shows, your previous screening history, your age, and whether you’ve had any prior treatment for precancerous changes. Mild cell changes are often monitored with repeat testing, since many resolve on their own. More advanced changes may be treated with procedures that remove the abnormal tissue from the cervix. The key point is that catching these changes early, before they progress to cancer, is exactly what the screening timeline is designed to do.
Vaccination and Its Limits
The HPV vaccine (Gardasil 9) protects against nine HPV types, including the two responsible for about 66% of cervical cancers in the U.S. and five additional cancer-causing types that account for roughly another 15%. It also covers the two low-risk types that cause most genital warts. Altogether, the vaccine addresses about 81% of cervical cancer cases.
Being vaccinated doesn’t eliminate the need for screening. The vaccine doesn’t cover every high-risk strain, and it can’t treat an infection you already have. If you were vaccinated before becoming sexually active, your protection is strongest, but the standard cervical screening schedule still applies regardless of vaccination status.
