Preventing and treating gynecologic cancer in San Diego

Scripps Cancer Center is a leader in caring for women with vulvar cancer. Experts in detecting precancerous cells, Scripps gynecologists eliminate many vulvar cancers in their earliest stages. Our oncology specialists treat vulvar cancer with advanced therapies designed to eliminate cancer and prevent recurrence, including minimally invasive surgery that uses small incisions, potentially resulting in shorter hospital stays and a faster recovery, and immunotherapy to harness the power of the body’s own immune system.


Our multidisciplinary, collaborative board of cancer specialists reviews every patient’s care plan to ensure you receive the best possible care from diagnosis to recovery.

About vulvar cancer

Vulvar cancer is a rare form of gynecologic cancer that affects the vulva, which is the outer part of a woman’s genitals. Other gynecological cancers include cervical, endometrial (uterine), ovarian and vaginal cancers.


The vulva includes the opening of the vagina, the labia majora (outer lips), the labia minora (inner lips) and the clitoris. Vulvar cancer most often affects the inner edges of the labia minora or labia majora. The disease tends to develop slowly over several years, and may start as precancerous changes that can be treated before they become cancer. Screening exams can help identify vulvar cancer early.


According to the American Cancer Society, vulvar cancer makes up fewer than 1% of cancers in women overall and about 4% of gynecologic cancers. In the United States, women have a 1 in 333 chance of developing vulvar cancer during their lifetime.

Types of vulvar cancer

Vulvar cancers can begin in different cell types. The most common types of vulvar cancer are squamous cell carcinomas, adenocarcinomas, melanomas and sarcomas.


Squamous cell carcinoma

Up to 90% of vulvar cancers are squamous cell carcinomas, which develop in the cells that line the cervix.


There are several subtypes of squamous cell carcinoma:


  • Keratinizing type is the most common. But it is not linked to infection with human papillomavirus (HPV).
  • Basaloid and warty types are less common. They most often affect younger women with HPV infections.
  • Verrucous carcinoma is an uncommon subtype that looks like a large wart.


Adenocarcinoma

About 8% of vulvar cancers are adenocarcinomas, which develop in the Bartholin gland cells found just inside the vaginal opening, or in the sweat glands of the vulvar skin. Bartholin gland cancers may be mistaken for cysts, which can delay a correct diagnosis.


Paget disease of the vulva, a type of adenocarcinoma, affects only the top layer of the skin. Up to a quarter of women with Paget disease also have a vulvar adenocarcinoma in a Bartholin gland or sweat gland. 


Melanoma

Melanoma skin cancers start in the cells that make skin pigment. This type of cancer is usually found in areas exposed to the sun, but in rare cases (about 6 out of 100), they may affect the vulvar skin.


Sarcomas

Sarcoma cancers start in the bones, muscles or connective tissue. Fewer than 2% of vulvar cancers are sarcomas.

Vulvar cancer causes, risks and family history

According to the American Cancer Society, up to half of basaloid and warty squamous cell cancers of the vulva appear to be associated with human papillomavirus (HPV) infection. Women who develop these cancers tend to be younger and are often smokers.


The second process by which vulvar cancers develop does not involve HPV infection. Squamous cell cancers of the vulva that aren’t linked to HPV infection usually affect women over age 55 and may develop from a condition called differentiated vulvar intraepithelial neoplasia, and may be associated with mutations of the p53 tumor suppressor gene. This gene plays an important role in preventing cells from becoming cancerous, and mutations may weaken that defense. It is not known how these gene mutations occur.


There are other known risk factors for vulvar cancer. Having these risk factors does not mean a woman will develop vulvar cancer, and some women who do have the disease have no risk factors.


Vulvar cancer risk factors include:


Human papillomavirus (HPV) infection

HPV infection has been linked to more than half of all vulvar cancers. For more on HPV, refer to the subsection below.


Age

Vulvar cancer risk increases with age. Fewer than 20% of cases are diagnosed in women under 50, while more than half of all cases occur in women older than 70. The average age for women diagnosed with invasive vulvar cancer is 70. For non-invasive vulvar cancer, the average age is 50.


Tobacco use

Smoking is a major risk factor for vulvar cancer. For women who have a history of high-risk HPV infection, smoking significantly raises the risk of vulvar cancer.


HIV infection

Infection with human immunodeficiency virus (HIV) damages the immune system, making HPV infection more likely and raising the risk for vulvar cancer.


Lichen sclerosis

This condition causes the skin in the vulva to become thin and itchy, and appears to slightly increase vulvar cancer risk. About 4% of women who have lichen sclerosis develop vulvar cancer.


Other genital cancers

Women who have cervical cancer tend to have a higher risk of vulvar cancer. This is likely due to the shared risk factors for the diseases, including HPV infection and smoking.


Melanoma or atypical moles

Women who have had melanoma skin cancer or atypical moles elsewhere on their skin have a higher risk for vulvar melanoma. A family history of melanoma also raises the risk.


Vulvar intraepithelial neoplasia (VIN)

VIN is the medical term for the precancerous changes that occur in the top layer of vulvar skin before squamous cell cancer develops. VIN can last for several years before the cells become cancer. In most cases, women with VIN will not develop cancer, but there is no way to know if it will or not, so medical care is important. The two types include usual-type VIN and differentiated-type VIN.


  • Usual-type VIN occurs in younger women and is caused by HPV infection. It can become the basaloid or warty subtypes of squamous cell carcinoma.
  • Differentiated-type VIN tends to occur in older women with no HPV link. It can become the keratinizing subtype of squamous cell cancer.


Having any of these risk factors does not mean you will develop vulvar cancer. But if you’re concerned about your risk, talk with your doctor. If you have family members who have had vulvar cancer, consider talking with one of our genetic counselors.


More on HPV

HPV is a group of more than 150 related viruses which can infect cells lining the genitals, anus, mouth and throat. It’s spread from one person to another during skin-to-skin contact, including sex. Infection with a high-risk type of HPV, such as HPV 16 or 18, may cause precancerous cell changes. If not treated, these cells may become cancerous.


Up to 80% of men and women who have had sex have HPV. In 9 out of 10 cases, the body’s immune system clears the virus on its own, and most women with HPV will not develop vulvar cancer. But if the infection becomes chronic, the risk of vulvar cancer increases. A vaccine series is available for HPV and is recommended for pre-teens between the ages of 11 and 12. In some cases, the vaccine may be recommended up to age 26.

Vulvar cancer prevention, screenings and early detection

There are no screening tests for vulvar cancer, but having annual pelvic exams can make it easier to detect precancerous changes or early-stage vulvar cancer, when treatment is most likely to be successful. Between exams, practice awareness — know the signs and symptoms of vulvar cancer and call your doctor if you notice anything unusual.


Preventive factors

Vulvar cancer cannot be completely prevented, but you can take the following steps to help with vulvar cancer prevention:


  • Avoid tobacco
  • Have annual pelvic exams
  • Have HPV tests as recommended by your physician
  • Ask your doctor about an HPV vaccine
  • Use condoms during sex to protect against sexually transmitted diseases
  • Have precancerous conditions treated

Vulvar cancer symptoms, diagnosis and stages

Most women have no vulvar cancer symptoms in the early stages of the disease. If symptoms do occur, they tend to vary. The precancerous changes called VIN usually cause no symptoms.


As with most cancers, the earlier vulvar cancer is found, the greater the likelihood of successful treatment. Learn more about symptoms, imaging and diagnostic testing, and the stages of vulvar cancer below.

Vulvar cancer symptoms

Vulvar cancer symptoms may include:


  • One or more red, pink or white bumps on the vulva, often with a rough or scaly surface
  • Burning, pain or itching in the vulvar area
  • Pain when you urinate
  • Bleeding and discharge not during a menstrual period
  • A sore on the vulva that does not heal for a month
  • A new mole or change in an existing mole in the genital area
  • Lump close to the opening to the vagina
  • Thickening of the skin of the vulva
  • Cauliflower-like growths on the vulva


Having any of these symptoms does not mean you have vulvar cancer, but do let your doctor know. It’s important to find the cause and any other potential issues.

Diagnostic testing

Should your physician recommend diagnostic testing, Scripps physicians diagnose and stage vulvar cancer using advanced imaging and lab tests. These include:


Vulvar biopsy

A biopsy is the only way to confirm a vulvar cancer diagnosis. During a biopsy, the doctor removes a tissue sample from the vulva to be examined under a microscope.


Computed tomography (CT) scan

A CT scan is an imaging test that captures images of the body from different angles. The images are combined to create detailed cross-sectional views of organs, bones and blood vessels.


Magnetic resonance imaging (MRI)

MRI relies on a powerful magnet, radio waves and advanced digital technology to provide detailed images of organs, bone and soft tissue.


Positron emission tomography (PET) scan

A PET scan involves a type of radioactive sugar that existing cancer cells will quickly absorb so they can be identified under a special camera. It’s combined with a CT scan to give physicians the ability to view a picture of potentially cancerous areas through the PET while also seeing more detailed images from a CT scan. 

Vulvar cancer stages

Staging vulvar cancer determines how far cancer may have spread beyond its starting point, and whether it affects other parts of the body. Staging helps cancer specialists develop the vulvar cancer prognosis and treatment plan.


Stage 0

Abnormal cells are found on the surface of the vulvar skin and may become cancer. Stage 0 also is called carcinoma in situ.


Stage I

Stage I vulvar cancer is confined to the vulva only. Stage I is divided into several substages based on the size of the cancer and where it’s located.


Stage IA is when the lesion is 2 cm or smaller and:


  • Is confined to the vulva or perineum (the area between the anus and vagina)
  • Has spread into the stroma (the underlying tissue beneath the surface) 1 millimeter or less
  • Has not spread into the surrounding lymph nodes


Stage IB is when the lesion is more than more than 2 cm in size and:


  • Has spread more than 1 millimeter into the stroma
  • Is confined to the vulva or perineum
  • Has not spread into surrounding lymph nodes


Stage II

In stage II vulvar cancer, the tumor is any size and has spread to perineal structures next to the vulva (such as the anus, lower third of urethra or lower third of the vagina), but not to surrounding lymph nodes.


Stage III

In stage III vulvar cancer, the tumor is any size and may or may not have spread to perineal structures near the vulva, but cancer has spread to the lymph nodes.


Stage IV

In stage IV vulvar cancer, the tumor has spread to other nearby regions (such as the upper two-thirds of the urethra or upper two-thirds of the vagina) or to distant body parts.

Understanding your diagnosis

No woman wants to learn that she’s been diagnosed with vulvar cancer. You may feel frightened, overwhelmed, anxious or sad. These are all normal, common reactions, and the more you learn about your diagnosis, the sooner you can begin to make informed decisions about your options.


Questions and considerations

Here are some questions you may want to ask your doctor or health insurance provider regarding your diagnosis:


  • Should I get a second opinion?
  • How do I find a specialist?
  • What is my cancer treatment plan?
  • Will I have to miss work/school?
  • What are the side effects of vulvar cancer treatment?
  • How successful is my treatment likely to be?
  • What costs will be covered by insurance?
  • Which costs will I be responsible for?


Your Scripps team is here to help you find the answers you need to take an active role in your care. In addition, there are a number of community cancer resources that provide education, information and helpful resources — often at no cost.

Vulvar cancer treatment options at Scripps

Your Scripps cancer care team will customize your treatment plan based on several factors, including:


  • The cancer stage
  • Whether cancer has spread
  • Your age and overall health


Treatment for precancerous vulvar intraepithelial neoplasia (VIN) or early-stage vulvar cancer usually involves surgery. More advanced cases may include chemotherapy or radiation therapy.


Topical therapy

In some cases, physicians may be able to treat early precancerous vulvar cell changes with medicine applied to the area.


Vulvar cancer surgery

Depending on the stage of the cancer and how far it may have spread, Scripps physicians may use several surgical procedures to treat vulvar cancer. These include:


  • Laser surgery is when the physician uses a laser beam to destroy abnormal cells.
  • Excision is when the cancer and about a ½ inch of skin on each side of it are removed.
  • Vulvectomy is when some or all of the vulva is removed. After this procedure, a plastic surgeon may perform reconstructive surgery.
  • Lymph node dissection is when surgeons remove lymph nodes from the pelvic region to see if the cancer has spread. This can be performed through a minimally invasive laparoscopic surgery.
  • Pelvic exenteration is the most extensive surgical approach and is used for advanced vulvar cancer. It involves the removal of the vulva and lymph nodes, and may include the removal of the cervix, uterus, bladder, vagina, rectum and possibly part of the colon, based on how far the cancer has spread.


With pelvic exenteration, the following organs may be involved:


  • If the bladder is removed, the surgeon may use a piece of intestine to form a new bladder, and urine may be drained through a catheter (tube) into a small plastic bag worn outside of the body.
  • If the rectum and part of the colon are removed, you may have an opening on the abdomen that allows solid waste (stool) to pass into a small bag worn on the outside of the body, called a colostomy. In some cases, the surgeon may be able to reconnect the colon, so no colostomy is needed.
  • If the vagina is removed, the surgeon may be able to make a new one from other tissue.


Chemotherapy

Chemotherapy may be used to shrink tumors before surgery, or when the disease has spread beyond the pelvis. It may be used in combination with radiation therapy.


Radiation therapy

Radiation therapy may be used to treat vulvar cancers that have spread, or to shrink large tumors before surgery. Scripps radiation oncologists use advanced radiation therapy techniques that precisely target tumors while minimizing radiation exposure to nearby healthy tissues and organs.

Vulvar cancer clinical trials

Some vulvar cancer treatment plans may involve clinical trials. Talk with your physician about whether a clinical trial is right for you.


For a list of clinical trial that are currently enrolling patients, see our current list of clinical trials.

Your custom cancer treatment plan

Your Scripps cancer team will develop a customized treatment plan outlining the treatments and therapies we recommend for your care. Before you begin treatment, you and your physician will review your plan together and discuss any questions or concerns you may have.


Your vulvar cancer treatment plan generally includes:


  • Family and medical history
  • A summary of your cancer diagnosis and staging information
  • Diagnostic testing completed (e.g., imaging, biopsy, lab tests)
  • Plans for surgery, radiation, chemotherapy and/or other treatments
  • Potential side effects of treatments
