Understanding Vulvar Cancer: Symptoms, Types, Causes, Diagnosis, and Treatment

Key Takeaways

  • Squamous cell carcinoma accounts for 90% of cases, typically developing in women over 70, while melanoma represents 5% and occurs at younger ages with worse prognosis.

  • HPV types 16 and 18 cause approximately 40% of cases, with HPV-related tumors generally responding better to treatment than those caused by chronic inflammation.

  • Stage I five-year survival rates exceed 90% when cancer remains localized, dropping to 57% once it spreads to lymph nodes or distant organs.

  • Surgical treatment ranges from local excision for early-stage tumors to radical vulvectomy with lymph node removal, potentially requiring reconstructive surgery for larger lesions.

  • The HPV vaccine (Gardasil 9) prevents up to 90% of HPV-related cases when administered before age 26, though catch-up vaccination is recommended through age 45.

Vulvar cancer is a type of cancer that develops in the vulva, the outer part of a woman's genitals. It is important to be aware of the symptoms, causes, and risk factors associated with this condition to ensure early detection and effective treatment.

What is Vulvar Cancer?

Vulvar cancer occurs when cancerous cells grow uncontrollably in the vulva. The vulva includes the opening of the vagina, the labia (skin folds), the clitoris, the mons pubis (soft mound of tissue), and the perineum (area between the vulva and anus). It is different from vaginal cancer, which starts inside the vagina.

Understanding Vulvar Cancer: Symptoms, Types, Causes, Diagnosis, and Treatment

Symptoms of Vulvar Cancer

In the early stages, vulvar cancer may not present any noticeable symptoms. However, as the condition progresses, you may experience:

  • Changes in the color or appearance of the vulva

  • Unusual growths, bumps, or thickened skin

  • Changes in the appearance of moles

  • Persistent itching or burning sensation

  • Pain or soreness in the vulvar area

  • Unusual vaginal bleeding or discharge

  • Pain during urination

If you notice any of these symptoms, it is crucial to consult your doctor promptly for an accurate diagnosis.

Types of Vulvar Cancer

There are several types of vulvar cancer, including:

  • Squamous cell carcinoma: The most common type, starting in the skin cells of the vulva.

  • Adenocarcinoma: Develops in the Bartholin's glands or sweat glands of the vulva.

  • Melanoma: Originates in the pigment-producing cells of the skin.

  • Sarcoma: Starts in the bone, muscle, or connective tissue cells.

  • Basal cell carcinoma: Rarely occurs on the vulva but is the most common type of skin cancer.

Causes and Risk Factors

The exact causes of vulvar cancer are not well understood, but certain factors can increase your risk, such as:

  • Advanced age (over 70 years)

  • Human papillomavirus (HPV) infection

  • Smoking

  • Weakened immune system (e.g., HIV/AIDS)

  • Precancerous conditions like vulvar intraepithelial neoplasia (VIN)

  • History of cervical or vaginal cancer

  • Skin conditions like lichen sclerosus

Diagnosing Vulvar Cancer

To diagnose vulvar cancer, your doctor may perform the following tests:

  • Pelvic exam and medical history

  • Colposcopy or vulvoscopy (close examination of the vulva)

  • Biopsy (tissue sample analysis)

  • Imaging tests (X-rays, CT scans, MRIs)

Based on the results, your doctor will determine the stage of the cancer, which indicates its size and extent of spread.

Treatment Options

Treatment for vulvar cancer depends on various factors, such as the type and stage of the cancer and your overall health. The main treatment options include:

  • Surgery: Removal of the cancerous tissue and possibly nearby lymph nodes.

  • Radiation therapy: Using high-energy beams to kill cancer cells.

  • Chemotherapy: Administering medications to destroy cancer cells.

  • Biologic therapy (immunotherapy): Boosting the body's immune system to fight cancer.

Your doctor will work with you to develop a personalized treatment plan based on your specific needs and preferences.

Preventing Vulvar Cancer

While not all cases of vulvar cancer can be prevented, you can take steps to reduce your risk:

  • Get vaccinated against HPV

  • Practice safe sex and limit your number of sexual partners

  • Avoid smoking

  • Attend regular gynecological check-ups

  • Report any unusual symptoms to your doctor promptly

By being proactive about your health and seeking timely medical assistance, you can improve your chances of successful treatment and recovery.

The Bottom Line

Early-stage vulvar cancer has excellent survival rates above 90%, making prompt evaluation of persistent vulvar symptoms crucial for optimal outcomes. Regular gynecologic exams and HPV vaccination provide the best prevention strategy, especially for women with risk factors like smoking or immunosuppression. If you're experiencing unexplained vulvar changes, persistent itching, or unusual growths, Doctronic can help you get expert guidance quickly.
