Vulvar cancer is a rare but serious condition that affects the external female genitalia. Though it accounts for only a small percentage of gynecological cancers, its impact on women’s health and quality of life can be significant. Understanding this disease is crucial for early detection and successful treatment.
This guide aims to provide a comprehensive overview of vulvar cancer. It will cover the basics of the disease, including its causes and risk factors. The guide will also discuss common symptoms to watch out for, explain the diagnosis and staging process, and outline various treatment options available. By the end, readers will have a clearer understanding of vulvar cancer and be better equipped to address any concerns they may have.
The Basics of Vulvar Cancer
Vulvar cancer is a rare type of cancer that develops on the outer surface of the female genitalia, known as the vulva. It most commonly affects the inner edges of the labia majora or labia minora. While vulvar cancer can occur at any age, it is most frequently diagnosed in older women.
What is Vulvar Cancer?
Vulvar cancer begins when healthy cells in the vulva develop changes (mutations) in their DNA. The abnormal cells grow and multiply out of control, forming a mass or tumor. The cancer cells can then invade nearby tissue and potentially spread to other parts of the body. The most common type of vulvar cancer is squamous cell carcinoma, which accounts for about 90% of cases. It develops in the thin, flat cells that line the surface of the vulva. Other less common types include vulvar melanoma, Paget’s disease of the vulva, verrucous carcinoma, basal cell carcinoma, sarcoma, and Bartholin’s gland carcinoma.

Types and Stages
The type of vulvar cancer is determined by the kind of cell in which it originated. Staging describes how far the cancer has spread. The stages of vulvar cancer range from I to IV, with higher numbers indicating more advanced disease. In Stage I, the cancer is confined to the vulva or perineum. Stage II involves the tumor spreading to the lower parts of the urethra, vagina, or anus. By Stage III, the cancer has reached the lymph nodes or nearby tissues of the upper urethra, vagina, bladder, or rectum. Stage IV indicates the cancer has spread to distant parts of the body or has become fixed to the pelvic bone. Determining the type and stage of vulvar cancer is crucial for developing an effective treatment plan. Early detection and prompt treatment can significantly improve outcomes for those diagnosed with this rare but serious form of cancer.
Identifying Symptoms
The most common symptom of vulvar cancer is a lump or sore on the vulva that does not heal. This lump may be red, pink, or white, and may have a wart-like or raw surface. It can appear on the labia, clitoris, or perineum. In some cases, vulvar cancer may cause itching, burning, or bleeding in the vulvar area.
Physical Changes
Women with vulvar cancer may notice several physical changes in the vulvar region. These can include skin thickening, discoloration, or the appearance of a rash or warts. Some women may develop open sores or ulcers that do not heal. Any persistent changes in the appearance of the vulva should be evaluated by a healthcare provider.

Pain and Discomfort
Vulvar cancer can cause pain, tenderness, or a feeling of pressure in the vulva. Some women describe it as a burning sensation or a feeling of rawness. The discomfort may be constant or may come and go. It can be severe enough to interfere with sitting, walking, or sexual activity. Pain during urination or defecation can also be a sign of vulvar cancer.
When to Seek Medical Attention
Any symptoms of vulvar cancer should be promptly evaluated by a healthcare professional. This is especially important for symptoms that last more than a few weeks. Women should not try to diagnose vulvar cancer on their own or attempt to treat symptoms with over-the-counter medications. A delay in diagnosis and treatment can allow the cancer to progress and make it more difficult to treat. Early detection and treatment of vulvar cancer offers the best chance for a cure. Women should discuss any concerns about vulvar health with their healthcare providers, even if they feel embarrassed or unsure. Regular gynecologic exams can help detect vulvar cancer early, before symptoms develop.
Diagnosis and Staging Process
Initial Examination
The diagnosis of vulvar cancer begins with a thorough physical examination, including a pelvic exam. The doctor carefully inspects the vulva for any visible abnormalities, such as lumps, sores, or changes in skin color or texture. A colposcopy, which uses a special magnifying device, may be performed to examine the vulva more closely. If suspicious areas are identified, the doctor may recommend a biopsy.
Biopsy and Imaging
A biopsy involves removing a small sample of tissue from the abnormal area for examination under a microscope. The two main types of biopsies used in diagnosing vulvar cancer are punch biopsy and excisional biopsy. In a punch biopsy, a small piece of tissue is removed from a larger abnormal area, while an excisional biopsy removes the entire abnormal area. Imaging tests, such as CT, MRI, or PET scans, may be used to determine if the cancer has spread to nearby lymph nodes or other parts of the body.
Determining the Stage
Once vulvar cancer is confirmed, the doctor works to determine the extent of the cancer, a process called staging. The stage of vulvar cancer is based on the size of the tumor, the depth of invasion into the vulvar tissue, and whether it has spread to nearby lymph nodes or distant parts of the body. The staging system most commonly used for vulvar cancer is the FIGO system, which ranges from Stage I (early-stage cancer confined to the vulva) to Stage IV (advanced cancer that has spread to nearby structures or distant parts of the body). Accurate staging is crucial for developing an effective treatment plan tailored to the individual patient’s needs.
Comprehensive Treatment Plan
The optimal surgical management of vulvar cancer needs to consider dimensions, staging, depth of invasion, presence of carcinoma at the surgical margins of resection and grading, with the goal of making the treatment as individualized as possible. More personalized and conservative surgical approaches, consisting of wide local or wide radical excisions, are necessary to reduce complications such as lymphedema or sexual dysfunction. The benefits of personalized approaches by multidisciplinary integration, based on tumor board discussion, are also clearly emerging with the need to address cases to dedicated reference centers.
Tailoring Treatment to the Individual
Treatment for vulvar cancer depends on its characteristics and stage, as well as the patient’s overall health, preferences, and goals. Options include surgery, radiation therapy, and chemotherapy. Using the latest advancements in surgical technologies and tools, a growing number of minimally invasive and laparoscopic techniques are available for surgically treating vulvar cancer in appropriate patients. Types of surgeries include laser surgery, excision, vulvectomy, and pelvic exenteration.

Treatment Options
Radiation can be administered in conjunction with chemotherapy to reduce the size of the cancer before surgery. The most common type is external-beam radiation therapy, which uses high-energy X-rays to deliver radiation that destroys cancer cells while sparing the surrounding healthy tissues. Chemotherapy can also be given with radiation therapy to reduce the cancer size before surgery.
Managing Side Effects
All treatments for vulvar cancer can have side effects. Some go away quickly; others can take weeks, months or even years to improve. The treatment team will discuss the likely side effects before treatment starts. Vulvar cancer and its treatment can sometimes lead to long-term, life-changing side effects, such as changes to how the vulva and vagina look and feel, bladder changes, lymphedema and impact on sexuality. It is important to give yourself and those around you time to deal with the emotions that a diagnosis of vulvar cancer can cause. It can help to share how you’re feeling about treatment side effects with a counselor or psychologist.
