Do Genital Warts Cause Cancer? Distinguishing Low-Risk from High-Risk HPV

When I diagnose a patient with genital warts, the question that never leaves their lips but that I read in their eyes is always the same: "Is this cancer, will it turn into cancer?" I take this fear seriously because it's very common, and often blown out of proportion. In this article I'll explain the matter as clearly as I can: which HPV does what, which group your wart falls into, what the real risk is — and where it's actually right to direct your worry.

The key distinction: two HPV groups

Everything comes down to this distinction. HPV has hundreds of types, roughly split into two groups. Low-risk types (mainly 6 and 11): responsible for the vast majority of genital warts. These cause cell proliferation that produces visible but benign warts; their cancer-causing potential is very low. High-risk types (16, 18, and a few others): generally don't cause warts — they're stealthy; over the years they can create silent changes in cells that pave the way for cancers of the cervix, anal region, throat, and elsewhere. So here's the paradox: what you see (the wart) is usually the benign one; what's dangerous is linked to what you don't see (the high-risk type).

So will my wart turn into cancer?

The transformation of typical genital warts caused by low-risk types into cancer is very rare. I can say this with confidence. But I should add a few honest nuances: low-risk and high-risk types can be present together in the same person (having a wart doesn't guarantee you don't also carry a high-risk type — which is why screening matters); and in lesions neglected for a very long time, constantly irritated, or with an atypical appearance, cell changes can rarely occur. These nuances aren't a reason to panic — they're a reason not to skip treatment and follow-up. A biopsy provides a definitive distinction for lesions that look suspicious, change rapidly, bleed, or resist treatment.

What really matters: screening for high-risk HPV

Now that we've eased your mind about warts, let's redirect your attention to where it belongs. Because high-risk HPV works silently, you can't see it — you have to screen for it. In women: regular cervical screening (Pap smear/HPV test) catches the changes caused by high-risk types early — one of the most successful cancer-prevention programs in the world. Anal region: in high-risk groups (immunosuppressed individuals, those with a history of anal-genital HPV disease), anal screening may be considered. Being diagnosed with genital warts is a good reminder not to skip these screenings — because it shows you've come into contact with the HPV family.

The anal region and genital warts: my area of expertise

Warts around and inside the anal canal are especially important: they're often overlooked (it's common for warts visible outside to also be present inside), and this region is one that should be evaluated for changes linked to high-risk HPV over the long term. I gave a balanced account of the link between anal region tumors and HPV, and the importance of early diagnosis, in the article on anal cancer — as I emphasized there too: it's a rare disease, treatment success is high when caught early, and its biggest enemy is "brushing off what won't heal."

The heart of prevention: the HPV vaccine

Here's the strongest answer to this whole picture: the HPV vaccine targets both the low-risk types that cause warts and the high-risk types that cause cancer. In other words, the vaccine reduces both concerns in this article at once. While it's ideal to get it before becoming sexually active, it still has protective value at older ages and even in people who currently have warts (against types not yet encountered) — who it's recommended for is covered in the vaccine article. This vaccine, which can largely prevent cervical cancer, is the most concrete answer we can give to the fear of cancer.

Frequently asked questions

If I have a wart, has my cancer risk gone up?

The wart itself is not cancer, and if it's caused by a low-risk type, the risk of it turning into cancer is very low. However, since it shows you've come into contact with HPV, you should lower your threshold for screening (Pap smears in women) and follow-up — that's smart precaution, not increased risk.

Does it cause cancer in men too?

High-risk HPV is also linked to anal and certain other cancers in men — especially in immunosuppressed individuals. The vaccine and, in the necessary groups, anal screening protect men too; it isn't "just a women's issue."

If I get vaccinated, does my current cancer risk go away?

The vaccine protects against types you haven't yet encountered; it doesn't treat a high-risk type you already carry. That's why vaccination and screening go hand in hand — one manages the future, the other manages today.

My warts have been there for years; is that dangerous?

Lesions neglected for a long time, constantly changing, or atypical should be evaluated once — most of the time you'll get good news, but "it's been there for years" isn't reassurance, it's a reason for an exam. A biopsy clarifies anything suspicious.
