Most people with HPV never know they have it. The majority of infections cause no symptoms at all and clear on their own within a year or two. That’s what makes HPV tricky: you can carry and transmit the virus without any visible signs. The only reliable way to know if you have HPV is through medical testing, and even that is limited depending on your sex and the type of HPV involved.
Why HPV Usually Has No Symptoms
HPV is not one virus but a group of over 200 related strains. Some are considered low-risk and can cause genital warts. Others are high-risk and can, over years, lead to precancerous cell changes or cancer. But regardless of the strain, most infections are completely silent. Your immune system typically suppresses or eliminates the virus before it causes any noticeable changes, often within one to two years of exposure.
This means you could have been infected months or even years ago and never had a single symptom. It also means a current partner isn’t necessarily the source of a new diagnosis, since the virus can remain dormant for a long time before being detected.
Visible Signs That Can Appear
When HPV does produce symptoms, the most recognizable are genital warts. These appear as small bumps or clusters of bumps in the genital area. They can be raised or flat, small or large, and sometimes have an irregular, cauliflower-like texture. Warts can show up on the vulva, penis, scrotum, groin, thighs, or around the anus.
Genital warts are caused by low-risk HPV strains, meaning they don’t lead to cancer. They’re uncomfortable and sometimes cosmetically distressing, but they’re treatable. If you notice any unusual bumps, growths, lumps, or sores in the genital area, mouth, or throat, that warrants a visit to your healthcare provider.
High-risk HPV strains, the ones linked to cancer, almost never produce visible symptoms in their early stages. Cervical cell changes caused by these strains are painless and invisible to the naked eye. By the time symptoms like unusual vaginal bleeding, watery or bloody discharge, or pelvic pain appear, the changes may have already progressed to cervical cancer. This is exactly why routine screening matters so much.
How HPV Testing Works for Women
Screening is the primary way women find out they have HPV. Two types of tests use a sample of cervical cells collected with a swab during a pelvic exam:
- Pap smear: Checks for abnormal cervical cells that could become precancerous. It doesn’t detect the virus directly but identifies the damage it can cause.
- HPV test: Looks specifically for DNA from high-risk HPV strains. This is more sensitive than a Pap smear alone at catching precancerous changes early.
These tests can be done separately or together (called co-testing). HPV testing catches slightly more precancerous cases than a Pap smear alone, though it also has a higher rate of false positives, which can lead to follow-up procedures that turn out to be unnecessary.
When and How Often to Get Screened
The U.S. Preventive Services Task Force recommends different screening schedules by age. If you’re between 21 and 29, a Pap smear every three years is the standard approach. Starting at age 30 through 65, you have more options: a Pap smear every three years, an HPV test alone every five years, or both tests together every five years.
Screening is not recommended before age 21, regardless of sexual activity. After age 65, screening can generally stop if you’ve had consistently normal results over the years and aren’t at high risk. If you’ve had a hysterectomy that included removal of the cervix and you have no history of precancerous cervical changes, screening is also no longer needed.
Self-Collection HPV Tests
A newer option allows you to collect your own vaginal sample for HPV testing rather than having a provider do it during a pelvic exam. The FDA has approved self-collection both in clinical settings and, more recently, as an at-home option. Research shows self-collected samples are just as accurate as those taken by a provider.
There are some important differences, though. If your self-collected HPV test comes back negative, the recommended retest interval is every three years, compared to every five years for provider-collected samples. At-home testing still requires a healthcare provider to order the test and provide the collection device. It’s currently available to a limited number of people, though access is expected to expand. Self-collection is not recommended for people with a history of cervical cancer, HIV, organ transplants, or previous abnormal screening results.
HPV Testing for Men
This is where things get frustrating. There is no FDA-approved HPV test for men. The tests that exist are designed specifically for cervical cell samples and aren’t cleared for use on oral or anal tissue. For men, HPV is typically only discovered when visible warts appear or, in rarer cases, when an HPV-related cancer is diagnosed in the throat, anus, or penis.
Anal cancer screening using HPV tests has been explored for high-risk populations, but the approach hasn’t been standardized because HPV prevalence in the anal area is so high among at-risk groups that a positive test result isn’t very useful for narrowing down who needs treatment. In practice, most men with HPV are never diagnosed and never need to be, because their immune systems clear the infection without complications.
Oral HPV and Throat Cancer Signs
HPV can also infect the mouth and throat, and certain high-risk strains are now the leading cause of oropharyngeal cancer. Like genital infections, oral HPV usually produces no symptoms. There is no approved screening test for oral HPV.
Oropharyngeal cancer symptoms, when they eventually appear, include a persistent sore throat, earaches, hoarseness, swollen lymph nodes, pain when swallowing, and unexplained weight loss. Some people have no symptoms at all until the cancer is found during a dental or medical exam. These cancers are more common in men than women.
What Happens After a Positive HPV Test
A positive HPV test doesn’t mean you have cancer or will develop it. It means high-risk HPV DNA was found in your cervical cells, and your provider will want to monitor you more closely. The next step depends on the specifics. If your Pap smear was normal but your HPV test was positive, your provider may simply recommend retesting in a year to see if your body clears the infection on its own.
If abnormal cells were also found, the next step is usually a colposcopy, a procedure where your provider uses a magnifying instrument to closely examine the cervix for abnormal areas. If anything looks concerning, a small tissue sample (biopsy) is taken and examined under a microscope. Precancerous changes caught at this stage are highly treatable, which is the entire point of screening: catching and removing abnormal cells long before they could become cancer.
