Vulvar Cancer: Early Signs, Risk Factors, and How It Is Treated

Vulvar cancer is a cancer that starts in the tissues of the vulva, the outer part of the female genital area. Early signs often include persistent itching, a sore or lump, pain, bleeding, or skin changes that do not go away, and treatment depends on the stage and exact type of cancer.

Overview

Vulvar cancer is a cancer that develops in the vulva, which includes the outer female genital structures such as the labia and clitoris. It is less common than many other gynecologic cancers, but it is important because early changes can sometimes be subtle and mistaken for irritation, infection, or a skin condition.

The condition may begin as a persistent patch of abnormal skin, a lump, an ulcer, or an area of itching or burning that does not settle. In many people, vulvar cancer grows slowly, and some cases arise from precancerous changes that can be detected and treated before invasive cancer develops.

Several types of cancer can affect the vulva, but the most common is squamous cell carcinoma, which starts in the thin, flat cells that cover the skin. Less common forms include melanoma, basal cell carcinoma, adenocarcinoma, and Paget disease of the vulva. Because symptoms can overlap with benign conditions, a lasting change should be checked by a qualified doctor rather than self-treated for long periods.

Symptoms and early signs

Early vulvar cancer signs are often local and persistent rather than dramatic. The most common symptom is ongoing itching in one area of the vulva, especially if it keeps returning or does not improve with usual care. Some people notice a sore, wart-like growth, raised patch, thickened skin, or a change in color such as white, red, or darker areas.

Other symptoms can include burning, tenderness, pain, bleeding not related to menstruation, or discharge from a lesion. A lump or open sore that does not heal can be an important clue. Pain during urination or sexual activity may occur if the abnormal area is irritated or located near the vaginal opening or urethra.

Not every vulvar symptom means cancer. Infections, dermatitis, lichen sclerosus, and other skin disorders can cause similar complaints. However, symptoms that last more than a few weeks, come back repeatedly, or seem to worsen deserve medical attention.

• Persistent vulvar itching
• A lump, bump, or wart-like growth
• A sore or ulcer that does not heal
• Skin color change or thickening
• Pain, burning, or tenderness
• Bleeding or spotting unrelated to periods

Causes and risk factors

Vulvar cancer develops when cells in the vulva acquire genetic changes that make them grow abnormally. In some cases, it is linked to persistent infection with high-risk types of human papillomavirus, or HPV. In others, it is associated with chronic inflammatory or scarring skin conditions, particularly lichen sclerosus, which can increase long-term risk if not monitored carefully.

Age is an important factor, and vulvar cancer is more often diagnosed in older adults, although HPV-related cases can occur at younger ages. Smoking also raises risk because it affects immune function and makes it harder for the body to clear HPV infection. A weakened immune system, previous cervical or vaginal precancer, and a history of vulvar intraepithelial neoplasia can also contribute.

Having risk factors does not mean a person will develop cancer, and some people diagnosed with vulvar cancer have no obvious risk factor. Still, recognizing patterns can help with prevention and early evaluation. People with chronic vulvar skin disease or prior gynecologic precancer may need regular follow-up and careful symptom awareness.

Vulvar cancer can sometimes be related to broader gynecologic cancer care pathways, including evaluation for cervical cancer or other HPV-associated conditions when clinically appropriate.

How vulvar cancer is diagnosed

Diagnosis starts with a detailed medical history and physical examination, including a pelvic exam. A doctor looks closely at the vulva for areas of discoloration, thickening, ulceration, or growth. Because symptoms may resemble common skin conditions, visual inspection alone is not enough to confirm cancer.

The key test is a biopsy, in which a small sample of tissue is removed and examined under a microscope. This is the only way to determine whether the area is cancerous, precancerous, or benign. The pathology report also helps identify the exact cancer type and how deeply it has invaded surrounding tissue.

If vulvar cancer is confirmed, additional tests may be used to determine stage and treatment planning. These can include imaging such as ultrasound, CT, MRI, or PET scans, along with assessment of nearby lymph nodes, especially in the groin. In some cases, examination of the cervix, vagina, or anus may also be recommended to look for related abnormalities.

Accurate staging matters because treatment differs for small, localized lesions and more advanced disease. Referral to a gynecologic oncology team is often helpful to coordinate surgery, pathology review, and supportive care.

Treatment options

Vulvar cancer treatment depends on the cancer type, stage, location, size, lymph node involvement, overall health, and personal priorities. Surgery is often the main treatment for early-stage disease. The goal is to remove the tumor completely while preserving as much healthy tissue and function as possible.

Operations may range from removal of a small lesion with a margin of normal tissue to more extensive procedures when the cancer is larger or deeper. Nearby lymph nodes may also need assessment, sometimes with sentinel lymph node techniques in carefully selected cases. When surgery is not enough on its own, radiation therapy or chemotherapy may be added before or after the operation.

Radiation therapy can help treat the main tumor area, reduce the chance of recurrence, or target affected lymph nodes. Chemotherapy may be used alongside radiation in certain situations or for more advanced disease. Depending on the individual case, care may involve gynecologic oncology, radiation therapy, and medical oncology specialists working together.

Treatment planning also includes managing symptoms, sexual health, wound healing, body image concerns, and emotional wellbeing. For international patients, Acibadem International’s multidisciplinary specialists in JCI-accredited hospitals diagnose and treat vulvar cancer with coordinated care tailored to the person’s clinical needs.

Prevention and self-care

There is no guaranteed way to prevent vulvar cancer, but several steps may reduce risk and support earlier detection. HPV vaccination can help protect against the HPV types linked to some vulvar cancers. Avoiding smoking may also lower risk and improve overall gynecologic health.

Regular gynecologic checkups are important, especially for people with a history of HPV-related disease, chronic vulvar symptoms, or vulvar skin conditions such as lichen sclerosus. Following treatment plans for these conditions and attending recommended follow-up visits can help detect concerning changes early.

Self-care includes paying attention to the vulvar skin and not ignoring symptoms that persist. A person should seek evaluation for itching, pain, a sore, or a visible change that lasts or returns repeatedly. Gentle skin care, avoiding irritants, and using clinician-recommended treatments for underlying skin disorders may help reduce ongoing inflammation, though these steps do not replace medical assessment of suspicious lesions.

People with complex cases may also undergo evaluation alongside services such as PET-CT when imaging is needed to understand the extent of disease.

When to seek medical care

Medical care should be sought if vulvar itching, pain, burning, or a visible skin change does not improve after a short period or keeps coming back. An open sore, lump, bleeding unrelated to menstruation, or a patch that changes in size, color, or texture should also be assessed promptly.

Urgent evaluation is especially important if symptoms are worsening, interfering with urination or daily activities, or if there is a known history of vulvar precancer, HPV-related disease, or chronic vulvar skin conditions. Early assessment does not mean the problem is necessarily cancer, but it helps rule out serious causes and avoids delays in treatment.

Anyone who has been treated for vulvar cancer should continue follow-up as advised, because surveillance is important for monitoring healing, recurrence, and treatment-related side effects. A qualified gynecologist or gynecologic oncologist can guide next steps and explain whether biopsy, imaging, or specialist referral is needed.

Frequently asked questions

What is the first sign of vulvar cancer?

The first sign of vulvar cancer is often persistent itching or a noticeable skin change on the vulva. Some people first notice a lump, a sore that does not heal, or an area that becomes painful, thickened, or discolored.

Is vulvar cancer always caused by HPV?

No, vulvar cancer is not always caused by HPV. Some cases are linked to persistent high-risk HPV infection, while others are associated with chronic vulvar skin conditions such as lichen sclerosus or develop without a clear cause.

Can vulvar cancer be cured?

Many cases of vulvar cancer can be treated successfully, especially when found early. Outcomes depend on the stage, cancer type, lymph node involvement, and overall health, so prompt diagnosis is important.

How is vulvar cancer confirmed?

Vulvar cancer is confirmed with a biopsy. During this test, a small tissue sample is taken from the abnormal area and examined under a microscope to determine whether cancer cells are present.

What treatments are used for vulvar cancer?

Treatment may include surgery, radiation therapy, chemotherapy, or a combination of these options. The treatment plan is individualized based on the size and location of the tumor, the stage of disease, and whether nearby lymph nodes are involved.

Does vulvar cancer affect younger women?

Yes, although vulvar cancer is more common in older adults, it can also occur in younger women, particularly in HPV-related cases. Any persistent vulvar symptom should be checked regardless of age.
