Vulvar Cancer

Vulvar cancer is a rare gynecologic malignancy that arises from the tissues of the external female genitalia. Squamous cell carcinoma is the most common histologic type, although melanoma and other less common subtypes may also occur. Despite its rarity, early diagnosis becomes more likely when persistent itching, a sore, color change, a mass, or bleeding prompts timely biopsy. ^[1][2][3]

Vulvar cancer often does not begin with a single dramatic symptom. Instead, it may present as a chronic regional problem that slowly becomes more noticeable over time. In some people it begins with long-standing itching or irritation; in others it resembles a wart, ulcer, raised lesion, or plaque. Delaying evaluation because the problem is assumed to be a fungal infection or simple irritation can postpone diagnosis. ^[1][3][4]

What are the symptoms?

Symptoms may include persistent itching, pain, burning, a non-healing sore, skin thickening, a lump, color change, contact bleeding, or discomfort during sitting or intercourse. Some lesions are subtle at first and may resemble dermatologic conditions rather than an obvious tumor. ^[1][2][3]

Because many benign vulvar disorders also cause itching or irritation, symptoms alone do not establish the diagnosis. However, a lesion that persists, enlarges, bleeds, ulcerates, or fails to respond to routine treatment deserves formal gynecologic assessment and often biopsy. ^[1][2][4][5]

Risk factors and causes

Risk factors include increasing age, HPV-related disease, smoking, immunosuppression, and chronic vulvar disorders such as lichen sclerosus in selected pathways. Vulvar cancer is not a single biologic entity: some cases are associated with HPV, while others develop through non-HPV inflammatory or dysplastic pathways. ^[2][3][4][6]

This distinction matters because it affects prevention, surveillance, and the nature of precursor lesions. Persistent vulvar skin changes should therefore not be normalized or indefinitely self-treated without reassessment. ^[2][3][6]

How are diagnosis and staging performed?

Diagnosis generally requires biopsy. Physical examination alone is not sufficient to establish cancer type. Once malignancy is confirmed, further evaluation may include assessment of lesion size, depth, local extension, and lymph node involvement. Imaging and operative staging decisions depend on the individual case. ^[1][2][3]

Staging directly informs treatment planning. A small localized lesion may be approached differently from disease involving adjacent structures or regional lymph nodes. The central goal is to treat effectively while preserving function and quality of life as much as possible. ^[1][2][8]

What are the treatment options?

Treatment often includes surgery, but the exact approach depends on stage, histology, lesion location, and nodal status. Depending on the case, treatment may also involve sentinel node evaluation, lymph node surgery, radiotherapy, chemotherapy, or multimodal treatment planned by a gynecologic oncology team. ^[1][2][8]

Not every patient requires the same extent of surgery. Modern management increasingly aims to balance oncologic control with preservation of anatomy, sexual function, mobility, and wound healing. For this reason, treatment decisions are best made in a specialized setting when possible. ^[1][2][8]

When should you see a doctor?

Medical evaluation is appropriate for a vulvar lesion or symptom that persists, recurs, bleeds, changes color, causes pain, or does not improve with standard treatment. The same applies to new nodules, ulcers, or plaques, particularly in older adults or in people with known HPV-related disease or chronic vulvar dermatoses. ^[1][2][3]

Biopsy should not be excessively delayed when a suspicious lesion remains unexplained. Early recognition improves the likelihood of diagnosis at a more treatable stage. ^[1][2][7]

Follow-up and quality of life

Vulvar cancer care does not end after treatment. Follow-up visits monitor for recurrence, healing problems, lymphatic complications, urinary or sexual symptoms, and ongoing psychosocial needs. Some patients need support for body image, discomfort, sexual health, or scar-related symptoms. ^[1][2][8]

A coordinated, multidisciplinary approach may therefore improve not only cancer outcomes but also long-term quality of life. Personalized follow-up is especially important because treatment effects vary according to surgical extent and adjuvant therapy. ^[1][2][8]
