Vulvar Cancer: Early Detection and Diagnostic Approach

Vulvar cancer is a relatively rare form of cancer, accounting for approximately 3–5% of all gynaecological cancers worldwide. In India, the incidence remains low compared to other cancers, yet awareness is limited, often leading to delayed diagnosis. Vulvar cancer is more commonly seen in women over the age of 50; however, it can also occur in younger women, often associated with risk factors such as human papillomavirus (HPV) infection.

Because the early signs can be subtle and easily mistaken for common skin conditions, many women may ignore symptoms until the condition progresses. Early detection plays a critical role in improving outcomes and treatment success.

This blog provides a clear overview of vulvar cancer, including its symptoms, causes, stages, and available treatment options, helping patients and caregivers make informed decisions.

What is Vulvar Cancer?

Vulvar cancer refers to cancer that develops in the vulva, the external part of the female genitalia, which includes the labia, clitoris, and vaginal opening.

It typically begins as changes in the vulva’s skin cells and may develop slowly over time. In many cases, it starts as a precancerous condition before progressing to invasive cancer.

Therefore, recognising early changes and seeking timely medical advice is essential.

Recognising the Signs and Symptoms of Vulvar Cancer

Identifying early vulvar cancer symptoms can significantly improve treatment outcomes.

Common Symptoms

• Persistent itching or irritation in the vulvar area
• Pain or tenderness
• Changes in skin colour or texture
• A lump, sore, or ulcer that does not heal
• Unusual bleeding not related to menstruation

Early and Advanced Symptoms

In early-stage vulvar cancer, symptoms may be mild and easily overlooked. For example:

• Slight itching or discomfort
• Minor skin changes

However, in advanced stages, including stage 4 vulvar cancer symptoms, patients may experience:

• Severe pain
• Larger growths or ulcers
• Difficulty sitting or walking
• Spread of symptoms to nearby areas

Additionally, some symptoms may resemble signs of vaginal cancer, making proper diagnosis important.

What Causes Vulvar Cancer?

The exact vulvar cancer causes are not always clear. However, several risk factors are known to increase the likelihood of developing the condition:

• Infection with human papillomavirus (HPV)
• Chronic skin conditions affecting the vulva
• Smoking
• Weakened immune system
• Increasing age

Moreover, long-term irritation or inflammation may contribute to cellular changes.

Understanding the Stages of Vulvar Cancer

Vulvar cancer is classified into stages based on how far it has spread.

Stage 1: Localised Cancer

• Cancer is confined to the vulva or perineum (area between the vagina and anus)
• It has not spread to lymph nodes or nearby organs
• Often referred to as early-stage vulvar cancer
• Treatment outcomes are generally very good at this stage

Stage 2: Spread to Nearby Tissues

Cancer has spread to nearby structures such as:

• Lower urethra
• Lower vagina
• Anus

• No lymph node involvement yet
• Symptoms may become more noticeable

Stage 3: Lymph Node Involvement

• Cancer has spread to nearby lymph nodes in the groin
• May still involve nearby tissues
• The number and size of affected lymph nodes influence the severity

Stage 4: Advanced Cancer

This stage is further divided into two categories:

Stage 4A:

Cancer has spread to:

• Upper urethra
• Upper vagina
• Bladder or rectum
• Or has it extensively involved nearby lymph nodes

Stage 4B:

Cancer has spread to distant organs such as:

• Lungs
• Liver
• Other distant parts of the body

This is considered the most advanced stage, often associated with stage 4 vulvar cancer symptoms.

In early-stage vulvar cancer, treatment is often more effective, and outcomes are generally better. Therefore, early detection remains crucial.

Diagnosis and Treatment Options

Diagnosis

Doctors use several methods to diagnose vulvar cancer:

• Physical examination of the vulvar area
• Biopsy to confirm the presence of cancer cells
• Imaging tests such as CT or MRI scans
• Lymph node assessment

Treatment Options

Treatment depends on the stage and severity of the condition.

• Surgery: Removal of cancerous tissue
• Radiation therapy: Targets and destroys cancer cells
• Chemotherapy: Used in advanced cases or combined with other treatments

Therefore, a personalised treatment plan is developed based on individual needs.

Key Considerations and When to See a Doctor?

It is important to seek medical attention if symptoms persist or worsen.

You should consult a doctor if you notice:

• Persistent itching or discomfort
• Any lump or non-healing sore
• Unusual bleeding or discharge
• Changes in skin appearance

Moreover, regular gynecological check-ups can help detect abnormalities early.

Conclusion

Vulvar cancer is a rare but serious condition that requires timely attention and care. Recognising early vulvar cancer symptoms, including subtle changes seen in early-stage vulvar cancer, can significantly improve outcomes. Being aware of vulvar cancer causes and understanding the progression of the disease, including stage 1 vulvar cancer symptoms and stage 4 vulvar cancer symptoms, helps in early diagnosis and effective treatment.

Many patients often wonder if vulvar cancer is curable. The answer depends on the stage at diagnosis, but early detection greatly increases the chances of successful treatment. Additionally, recognising overlapping signs of vaginal cancer ensures accurate evaluation and care.
