Vulvar cancer is a relatively rare type of cancer that affects the external female genitalia, known as the vulva. This area includes the inner and outer lips of the vagina, the clitoris, and the opening of the vagina. While vulvar cancer accounts for a small percentage of gynecologic cancers, early detection is crucial for successful treatment outcomes. Understanding the warning signs and symptoms can help women seek medical attention promptly and improve their prognosis.
Most cases of vulvar cancer develop slowly over several years, often beginning as precancerous changes called vulvar intraepithelial neoplasia (VIN). Recognizing the symptoms early can make a significant difference in treatment options and survival rates. This article explores the most common signs and symptoms of vulvar cancer that every woman should be aware of.
1. Persistent Itching or Irritation
One of the earliest and most common symptoms of vulvar cancer is persistent itching in the vulvar area that doesn’t respond to typical treatments. This itching, medically known as pruritus vulvae, can be intense and unrelenting, significantly affecting quality of life.
Unlike temporary itching caused by infections or irritants, the itching associated with vulvar cancer tends to be chronic and progressive. It may worsen over time and doesn’t improve with over-the-counter remedies or standard antifungal treatments. The affected area may feel constantly irritated, leading to discomfort during daily activities.
Many women initially dismiss this symptom as a simple yeast infection or allergic reaction. However, if itching persists for more than two weeks despite treatment, or if it’s accompanied by other unusual symptoms, it’s essential to consult a healthcare provider for proper evaluation.
2. A Lump or Thickened Area on the Vulva
The development of a noticeable lump, bump, or thickened patch of skin on the vulva is a significant warning sign of vulvar cancer. These growths can vary in appearance and may feel firm or hard to the touch.
The lump may be raised above the surrounding skin or may appear as a thickened area that feels different from the normal vulvar tissue. Some lumps are painless, while others may be tender or sensitive. The size can range from very small, like a pea, to larger masses that are more easily detected.
These abnormal growths may develop on any part of the vulva, including the labia majora (outer lips), labia minora (inner lips), or near the clitoris. It’s important to perform regular self-examinations using a mirror to become familiar with your normal anatomy, making it easier to detect any new or unusual lumps early.
3. Changes in Skin Color or Texture
Vulvar cancer often causes visible changes to the skin’s appearance in the affected area. These changes can manifest in several ways and should not be ignored.
The skin may develop areas of discoloration, appearing white, red, pink, or darker than the surrounding tissue. White patches, called leukoplakia, are particularly significant and should always be evaluated by a healthcare professional. The affected skin may also appear thickened, rough, or develop a wart-like texture.
Some women notice that the skin looks shiny or has an unusual appearance compared to the rest of the vulvar area. The texture may feel different to the touch, sometimes appearing scaly or resembling a rash that doesn’t heal. These changes typically don’t resolve on their own and may gradually spread or become more pronounced over time.
4. Bleeding or Discharge Not Related to Menstruation
Unexplained bleeding from the vulvar area is a concerning symptom that requires immediate medical attention. This bleeding is not related to menstrual periods and occurs independently of the normal menstrual cycle.
The bleeding may be spontaneous, meaning it occurs without any obvious cause or trauma. Some women notice blood staining on their underwear or experience bleeding after sexual intercourse or physical activity. The amount of bleeding can vary from light spotting to heavier flow.
In addition to bleeding, some women with vulvar cancer experience unusual discharge from the vulva. This discharge may be bloody, watery, or have an unusual odor. Any abnormal bleeding or discharge, especially in postmenopausal women who are no longer having periods, should be promptly evaluated by a healthcare provider to determine the underlying cause.
5. Pain or Burning Sensation
Persistent pain, tenderness, or burning sensation in the vulvar area is another important symptom of vulvar cancer. This discomfort can significantly impact daily activities and quality of life.
The pain may be constant or intermittent, and it can range from mild discomfort to severe pain. Some women describe it as a burning, stinging, or aching sensation. The pain may worsen during certain activities such as urination, sexual intercourse, or when sitting for extended periods.
Unlike temporary pain from infections or injuries that typically improve with treatment, cancer-related pain tends to persist or worsen over time. The affected area may be extremely sensitive to touch, and even gentle contact with clothing or during hygiene routines may cause discomfort. This type of persistent pain that doesn’t respond to typical pain relief measures warrants a thorough medical examination.
6. An Open Sore or Ulcer That Doesn’t Heal
The development of an open sore, ulcer, or wound on the vulva that fails to heal is a significant red flag for vulvar cancer. Normal wounds and sores typically heal within a few weeks with proper care, but cancerous lesions persist.
These sores may appear as raw, eroded areas of skin that look similar to ulcers. They might bleed easily when touched or during activities like washing or sexual intercourse. The edges of the sore may be raised or irregular, and the base may have an unusual appearance.
A non-healing ulcer is particularly concerning because it indicates that the normal healing process is being disrupted, which can be a sign of underlying cancer. If you notice a sore on your vulva that hasn’t healed after three to four weeks, or if it appears to be getting worse despite proper hygiene and care, seek medical evaluation promptly.
7. Wart-Like Growths or Cauliflower-Shaped Masses
Some types of vulvar cancer present as wart-like growths or cauliflower-shaped masses on the vulva. These abnormal growths can be confused with genital warts but have distinct characteristics.
The growths may appear as raised, bumpy lesions that resemble the texture of a cauliflower. They can be single or multiple and may grow in size over time. While they might initially look similar to common genital warts caused by human papillomavirus (HPV), cancerous growths typically don’t respond to standard wart treatments and continue to grow or change.
These masses may be flesh-colored, white, pink, or red. They can develop anywhere on the vulva and may be accompanied by other symptoms such as itching, bleeding, or pain. Since HPV infection is a risk factor for vulvar cancer, any wart-like growth that persists, changes appearance, or develops unusual characteristics should be examined by a healthcare professional to rule out cancer.
Main Causes and Risk Factors
Understanding the causes and risk factors for vulvar cancer can help women take preventive measures and recognize their individual risk level. While the exact cause isn’t always known, several factors increase the likelihood of developing this condition:
Human Papillomavirus (HPV) Infection: Certain high-risk strains of HPV, particularly HPV 16 and 18, are strongly linked to vulvar cancer. HPV is a sexually transmitted infection that can cause cellular changes leading to cancer development over time.
Age: Vulvar cancer is more common in older women, with the average age of diagnosis being in the mid-60s to 70s. However, it can occur in younger women, especially those with certain risk factors.
Smoking: Tobacco use significantly increases the risk of vulvar cancer. Smoking weakens the immune system and may make it harder for the body to fight off HPV infections and prevent abnormal cell changes.
Vulvar Intraepithelial Neoplasia (VIN): This precancerous condition involves abnormal cell growth on the vulvar surface. If left untreated, VIN can progress to invasive cancer over several years.
Lichen Sclerosus: This chronic skin condition causes thin, white, patchy skin on the vulva and increases the risk of vulvar cancer. Women with lichen sclerosus require regular monitoring by a healthcare provider.
Weakened Immune System: Conditions or medications that suppress the immune system, such as HIV/AIDS or immunosuppressive drugs taken after organ transplantation, increase vulvar cancer risk.
History of Cervical Cancer or Precancer: Women who have had cervical cancer or precancerous cervical lesions have an elevated risk of developing vulvar cancer, likely due to shared risk factors like HPV infection.
Prevention Strategies
While not all cases of vulvar cancer can be prevented, several strategies can significantly reduce your risk and promote early detection:
HPV Vaccination: Getting vaccinated against HPV is one of the most effective preventive measures. The HPV vaccine protects against the high-risk strains most commonly associated with vulvar cancer. It’s most effective when given before sexual activity begins, but can still provide benefits to those already sexually active.
Practice Safe Sex: Using barrier methods like condoms during sexual activity can reduce the risk of HPV transmission, though they don’t provide complete protection since HPV can infect areas not covered by condoms.
Quit Smoking: If you smoke, quitting is one of the most important steps you can take to reduce your risk of vulvar cancer and improve overall health. Seek support from healthcare providers or smoking cessation programs to help you quit successfully.
Regular Gynecological Examinations: Annual pelvic exams allow healthcare providers to detect abnormal changes early. During these exams, your doctor can identify precancerous conditions or early-stage cancer when treatment is most effective.
Self-Examination: Perform monthly self-examinations of your vulvar area using a mirror in good lighting. Becoming familiar with your normal anatomy helps you quickly identify any changes, lumps, or unusual symptoms.
Prompt Treatment of Precancerous Conditions: If diagnosed with VIN, lichen sclerosus, or other precancerous conditions, follow your healthcare provider’s recommended treatment plan and attend all follow-up appointments to prevent progression to cancer.
Maintain Good Vulvar Hygiene: Keep the vulvar area clean and dry, avoid harsh soaps or irritants, and wear breathable cotton underwear. However, avoid excessive washing or douching, which can disrupt the natural balance and cause irritation.
Frequently Asked Questions
What does vulvar cancer look like in its early stages?
In early stages, vulvar cancer may appear as a small lump, bump, or thickened area on the vulva. It can also present as white, red, or darkened patches of skin, or as a persistent sore that doesn’t heal. Some early cancers look like wart-like growths. The appearance varies, which is why any unusual or persistent changes should be evaluated by a doctor.
Is vulvar cancer painful?
Vulvar cancer can cause pain, but not always in the early stages. Some women experience burning, tenderness, or aching sensations in the vulvar area. Pain may worsen during urination, sexual intercourse, or when sitting. However, some vulvar cancers are painless initially, making other symptoms like itching or visible changes more noticeable.
Can vulvar cancer be detected during a regular Pap smear?
No, a Pap smear screens for cervical cancer, not vulvar cancer. Vulvar cancer is typically detected through visual examination of the external genitalia during a pelvic exam. If abnormalities are found, a biopsy is performed to confirm the diagnosis. Regular pelvic exams that include inspection of the vulva are important for early detection.
How fast does vulvar cancer grow?
Vulvar cancer typically grows slowly over several years. It often begins as precancerous changes (VIN) that may take years to develop into invasive cancer. However, growth rates can vary depending on the type and individual factors. This slow progression provides opportunities for early detection and treatment when regular examinations are performed.
Who is at highest risk for developing vulvar cancer?
Women at highest risk include those over 60 years old, those with HPV infection (especially high-risk strains), smokers, women with a history of precancerous vulvar conditions (VIN) or lichen sclerosus, those with weakened immune systems, and women with a history of cervical cancer or precancer. Having multiple risk factors increases overall risk.
Can young women get vulvar cancer?
Yes, although vulvar cancer is more common in older women, younger women can develop it, particularly those with HPV infection or weakened immune systems. HPV-related vulvar cancers tend to occur in younger women compared to non-HPV-related types. Any woman experiencing persistent vulvar symptoms should seek medical evaluation regardless of age.
Is vulvar itching always a sign of cancer?
No, vulvar itching is a common symptom with many causes, most of which are not cancer. Yeast infections, bacterial vaginosis, skin conditions, allergies, and menopause are much more common causes of vulvar itching. However, persistent itching that lasts more than two weeks and doesn’t respond to standard treatments should be evaluated to rule out serious conditions including cancer.
What should I do if I notice symptoms of vulvar cancer?
If you notice any persistent or unusual symptoms in the vulvar area, schedule an appointment with your healthcare provider promptly. Don’t wait to see if symptoms resolve on their own. Your doctor will perform a physical examination and may recommend a biopsy if abnormalities are found. Early detection significantly improves treatment outcomes, so don’t delay seeking medical attention.
