Prevention Tips for Vulvar Cancer

• Vulvar cancer follows two distinct pathways: one tied to persistent HPV infection and typically appearing before age 50, and a second, HPV-independent pathway more common later in life that is tied to long-standing vulvar skin conditions, especially lichen sclerosus.
• HPV vaccination is a well-supported vulvar cancer prevention strategy. In the U.S., the vaccine given for this purpose, Gardasil 9, carries an FDA license covering vulvar cancer and related precancerous changes.
• Not smoking may help, since smoking can make it harder for the immune system to clear an existing HPV infection.
• There is no screening test for vulvar cancer in women without symptoms, so staying familiar with your body and getting chronic vulvar skin conditions diagnosed and treated are central to early detection.
• Persistent vulvar itching, burning, skin changes, sores, or bleeding that lasts two weeks or longer should be evaluated by a doctor promptly.

Understanding Vulvar Cancer Causes and Risks

The full picture of what drives vulvar cancer risk is detailed elsewhere; here the focus stays on the pieces that matter most for prevention. Roughly half of vulvar cancers trace back to long-term infection with a high-risk type of human papillomavirus (HPV), a route that tends to appear before age 50 and develops through a precancerous stage called vulvar intraepithelial neoplasia (VIN).

A second, HPV-independent group of vulvar cancers develops later in life and is tied instead to long-standing vulvar skin conditions — most notably lichen sclerosus, which causes persistent itching or burning. This two-track picture is why vulvar cancer prevention has two parts: lowering HPV-related risk through vaccination, and keeping chronic vulvar skin conditions monitored and treated.

Smoking adds a third contributing factor. Among women who already have an HPV infection, smoking is thought to blunt the immune response that would otherwise clear the virus, raising the odds that the infection lingers and leads to cell changes over time. A weakened immune system for other reasons, including HIV infection or immunosuppressive treatment, has a similar effect, leaving the body less able to clear HPV on its own.

Effective Vulvar Cancer Prevention Strategies

Because vulvar cancer can arise through more than one pathway, an effective approach to vulvar cancer prevention combines HPV vaccination with attention to smoking and chronic vulvar skin health, alongside prompt evaluation of any new symptoms.

The Role of HPV Vaccination

In the United States, the HPV vaccine given for this purpose is Gardasil 9, which the FDA has licensed for girls and women ages 9 through 45 to help prevent vulvar cancer, several other HPV-related cancers (cervical, vaginal, anal, and more), and vulvar intraepithelial neoplasia (VIN) grades 2 and 3, a precancerous condition. Because the vaccine only prevents new HPV infections and cannot clear one that is already present, it works best when given before a person has been exposed to HPV.

CDC guidance calls for routine HPV vaccination at ages 11 to 12, with the series allowed to start as early as age 9. Anyone not already vaccinated can still catch up through age 26. Adults from 27 to 45 who missed earlier vaccination may decide, together with their doctor, whether to get it later in life — the benefit tends to be smaller at this stage because many people in that age range have already encountered HPV.

Lifestyle Modifications for Risk Reduction

A few everyday choices can support vulvar cancer prevention, though none replace HPV vaccination on their own:

• Quit smoking: among women with an existing HPV infection, not smoking may help the immune system clear the virus more effectively, removing one contributing factor to vulvar cancer risk.
• Manage chronic vulvar skin conditions: because conditions such as lichen sclerosus are linked to the non-HPV pathway to vulvar cancer, getting persistent vulvar itching, burning, or skin changes diagnosed and treated by a doctor is a meaningful part of prevention.

Maintaining Vulvar Health and Early Detection

Unlike cervical cancer, there is currently no screening test for vulvar cancer in women who have no symptoms — the Pap test, in particular, does not screen for vulvar cancer. Because of this, staying familiar with what is normal for your body and reporting any changes promptly is central to early detection of vulvar cancer, especially for women managing a chronic vulvar skin condition or a prior diagnosis of vulvar intraepithelial neoplasia, for whom a doctor may recommend closer follow-up.

Common Symptoms to Watch For

Most women with vulvar cancer notice at least one symptom, which is exactly why staying attentive to vulvar changes supports earlier diagnosis. Plenty of ordinary, non-cancerous conditions cause similar signs, so the point isn’t to self-diagnose — it’s to get anything that lingers looked at.

Symptom	What to Watch For
Ongoing irritation	Itching, a burning sensation, or spotting in the vulvar area that lingers instead of settling down.
Skin tone changes	Patches of vulvar skin that turn darker, lighter, or noticeably more red than the tissue around them.
Texture changes	A thickened patch, or a spot that resembles a rash or a wart.
Non-healing sore	A growth or open sore on the vulva that fails to heal over several weeks.
Pelvic discomfort	Pain low in the pelvis, particularly during urination or intercourse.

Any vaginal bleeding outside your normal pattern deserves a same-week medical visit rather than a wait-and-see approach. The other changes listed above are worth a doctor’s opinion once they’ve stuck around past the two-week mark — most trace back to a harmless, treatable cause, but an exam is the only reliable way to rule out cancer.

Frequently Asked Questions

Is vulvar cancer common?

No, it is rare: vulvar cancer makes up roughly 0.3% of all new cancer diagnoses in the United States, translating to an estimated 7,130 cases in 2026 — a population-level figure, not a prediction of any one person’s odds. Most cases are found in women in their late 60s and beyond, with a typical age at diagnosis around 70, and the disease is more frequent among those who have previously had vulvar intraepithelial neoplasia, a high-risk HPV infection, or genital warts.

What are the most important steps for vulvar cancer prevention?

HPV vaccination is the most well-supported option, since it targets the viral types behind roughly half of vulvar cancers as well as several other HPV-related cancers. Skipping cigarettes and getting chronic vulvar skin conditions like lichen sclerosus diagnosed and treated cover the separate, non-HPV route to this disease. Since no general screening test exists for vulvar cancer, staying alert to your body and flagging new or lingering changes to a doctor rounds out a prevention-minded approach.

When should I see a doctor about vulvar symptoms?

Contact your doctor without delay for any bleeding pattern that differs from your usual cycle. For other changes — persistent irritation, a shift in vulvar skin tone or texture, a sore that won’t heal, or pelvic discomfort — schedule a visit once the issue has lasted two weeks. A benign cause is common, but only an exam can confirm that.
