General Information About Vulvar Cancer

Key Points

  • Vulvar cancer is a rare cancer that starts in the tissues of the vulva.
  • Having vulvar intraepithelial neoplasia or HPV infection can increase the risk of vulvar cancer.
  • Signs of vulvar cancer include bleeding or itching in the vulvar area.
  • Tests that examine the vulva are used to diagnose vulvar cancer.
  • Certain factors affect prognosis (chance of recovery) and treatment options.

Vulvar cancer is a rare cancer that starts in the tissues of the vulva.

Vulvar cancer forms in a woman's external genitalia, called the vulva. It occurs when cells in the vulva start to grow out of control. The vulva includes:

  • the inner and outer lips of the vagina
  • the clitoris (the sensitive tissue above the lips of the vagina)
  • the opening of the vagina and its glands
  • the mons pubis (the rounded area in front of the pubic bones that becomes covered with hair at puberty)

Vulvar cancer most often affects the outer vaginal lips. Less often, cancer affects the inner vaginal lips, clitoris, or vaginal glands.

Vulvar cancer usually forms slowly over many years. Abnormal cells can grow on the surface of the vulvar skin for a long time. This condition is called vulvar intraepithelial neoplasia (VIN). Because it is possible for VIN to become vulvar cancer, it is important to get treatment.

Having vulvar intraepithelial neoplasia or HPV infection can increase the risk of vulvar cancer.

Anything that increases a person's chance of getting a disease is called a risk factor. Not every person with one or more of these risk factors will develop vulvar cancer, and it will develop in some people who don't have any known risk factors. Talk with your doctor if you think you may be at risk. Risk factors for vulvar cancer include:

Other possible risk factors include:

  • having many sexual partners
  • having first sexual intercourse at a young age
  • having a history of abnormal Pap tests (Pap smears)

Signs of vulvar cancer include bleeding or itching in the vulvar area.

Vulvar cancer often does not cause early signs or symptoms. Signs and symptoms may be caused by vulvar cancer or by other conditions. Check with your doctor if you have any of the following:

  • a lump or growth on the vulva that looks like a wart or ulcer
  • itching in the vulvar area that does not go away
  • bleeding not related to menstruation (periods)
  • pain in the vulvar area

Tests that examine the vulva are used to diagnose vulvar cancer.

In addition to asking about your personal and family health history and doing a physical exam, your doctor may perform the following tests and procedures:

  • Pelvic exam: An exam of the vagina, cervix, uterus, fallopian tubes, ovaries, and rectum. A speculum is inserted into the vagina and the doctor or nurse looks at the vagina and cervix for signs of disease. A Pap test of the cervix is usually done. The doctor or nurse also inserts one or two lubricated, gloved fingers of one hand into the vagina and places the other hand over the lower abdomen to feel the size, shape, and position of the uterus and ovaries. The doctor or nurse also inserts a lubricated, gloved finger into the rectum to feel for lumps or abnormal areas.

This is done to feel the size, shape, and position of the uterus and ovaries. The vagina, cervix, fallopian tubes, and rectum are also checked.
  • Pap test: A procedure to collect cells from the surface of the cervix and vagina. A piece of cotton, a brush, or a small wooden stick is used to gently scrape cells from the cervix and vagina. The cells are viewed under a microscope to find out if they are abnormal.
  • Human papillomavirus (HPV) test: A laboratory test used to check DNA or RNA for certain types of HPV infection. Cells are collected from the vulva and DNA or RNA from the cells is checked to find out if an infection is caused by a type of human papillomavirus that is linked to vulvar cancer. This test may be done using the sample of cells removed during a Pap test. This test may also be done if the results of a Pap test show certain abnormal vulvar cells.
  • Biopsy: The removal of cells or tissues from the vulva so they can be viewed under a microscope by a pathologist to check for signs of cancer.
  • Colposcopy: A procedure in which a colposcope (a lighted, magnifying instrument) is used to check the vagina and cervix for abnormal areas. Tissue samples may be taken using a curette (spoon-shaped instrument) or a brush and checked under a microscope for signs of disease.
  • MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI).
  • CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
  • PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do.

Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis and treatment options depend on:

  • whether the cancer has spread to nearby areas or other parts of the body
  • whether the cancer has spread to the lymph nodes
  • whether the cancer has just been diagnosed or has recurred (come back)

Stages of Vulvar Cancer

Key Points

  • After vulvar cancer has been diagnosed, tests are done to find out if cancer cells have spread within the vulva or to other parts of the body.
  • There are three ways that cancer spreads in the body.
  • Cancer may spread from where it began to other parts of the body.
  • In vulvar intraepithelial neoplasia (VIN), abnormal cells are found on the surface of the vulvar skin.
  • The following stages are used for vulvar cancer:
    • Stage I
    • Stage II
    • Stage III
    • Stage IV
  • Vulvar cancer can recur (come back) after it has been treated.

After vulvar cancer has been diagnosed, tests are done to find out if cancer cells have spread within the vulva or to other parts of the body.

The process used to find out if cancer has spread within the vulva or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The following tests and procedures may be used in the staging process:

  • Cystoscopy: A procedure to look inside the bladder and urethra to check for abnormal areas. A is inserted through the urethra into the bladder. A cystoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer.
  • Proctoscopy: A procedure to look inside the rectum and anus to check for abnormal areas, using a proctoscope. A proctoscope is a thin, tube-like instrument with a light and a lens for viewing the inside of the rectum and anus. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer.
  • Chest x-ray: An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. To stage vulvar cancer, x-rays may be taken of the organs and bones inside the chest.
  • Intravenous pyelogram (IVP): A series of x-rays of the kidneys, ureters, and bladder to find out if cancer has spread to these organs. A contrast dye is injected into a vein. As the contrast dye moves through the kidneys, ureters and bladder, x-rays are taken to see if there are any blockages. This procedure is also called intravenous urography.
  • Biopsy: The removal of cells or tissues from the bladder or rectum so they can be viewed under a microscope by a pathologist to check for signs of cancer, if it is suspected that cancer has spread there.

There are three ways that cancer spreads in the body.

Cancer can spread through tissue, the lymph system, and the blood:

  • Tissue. The cancer spreads from where it began by growing into nearby areas.
  • Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
  • Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.

Cancer may spread from where it began to other parts of the body.

When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.

  • Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body.
  • Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body.

The metastatic tumor is the same type of cancer as the primary tumor. For example, if vulvar cancer spreads to the lung, the cancer cells in the lung are actually vulvar cancer cells. The disease is metastatic vulvar cancer, not lung cancer.

Many cancer deaths are caused when cancer moves from the original tumor and spreads to other tissues and organs. This is called metastatic cancer. This animation shows how cancer cells travel from the place in the body where they first formed to other parts of the body.

In vulvar intraepithelial neoplasia (VIN), abnormal cells are found on the surface of the vulvar skin.

These abnormal cells are not cancer. Vulvar intraepithelial neoplasia (VIN) may become cancer and spread into nearby tissue. VIN is sometimes called stage 0 or carcinoma in situ.

The staging system below does not apply to melanoma of the vulva, which is staged like melanoma of the skin. For more information, see the Stage Information for Melanoma section in Melanoma Treatment.

The following stages are used for vulvar cancer:

Stage I

In stage I, cancer has formed. The tumor is found only in the vulva. Stage I is divided into stages IA and IB.

EnlargeDrawing shows different sizes of a tumor in centimeters (cm) compared to the size of a pea (1 cm), a peanut (2 cm), a grape (3 cm), a walnut (4 cm), a lime (5 cm), an egg (6 cm), a peach (7 cm), and a grapefruit (10 cm). Also shown is a 10-cm ruler and a 4-inch ruler.
Tumor sizes are often measured in centimeters (cm) or inches. Common food items that can be used to show tumor size in cm include: a pea (1 cm), a peanut (2 cm), a grape (3 cm), a walnut (4 cm), a lime (5 cm or 2 inches), an egg (6 cm), a peach (7 cm), and a grapefruit (10 cm or 4 inches).

  • In stage IA, the tumor is 2 centimeters or smaller and has spread 1 millimeter or less into the tissue of the vulva. Cancer has not spread to the lymph nodes.
  • In stage IB, the tumor is larger than 2 centimeters or has spread more than 1 millimeter into the tissue of the vulva. Cancer has not spread to the lymph nodes.

    Millimeters (mm). A sharp pencil point is about 1 mm, a new crayon point is about 2 mm, and a new pencil eraser is about 5 mm.

Stage II

In stage II, the tumor is any size and has spread to the lower one-third of the urethra, the lower one-third of the vagina, or the lower one-third of the anus. Cancer has not spread to the lymph nodes.

Stage III

In stage III, the tumor is any size and has spread to the upper two-thirds of the urethra, the upper two-thirds of the vagina, the inner lining of the bladder or rectum, or to any number of lymph nodes. Stage III is divided into stages IIIA, IIIB, and IIIC.

  • In stage IIIA, cancer is found in lymph nodes in the groin that are not larger than 5 millimeters.
  • In stage IIIB, cancer is found in lymph nodes in the groin that are larger than 5 millimeters.
  • In stage IIIC, cancer is found in lymph nodes in the groin and has extended through the outer covering of the lymph nodes.

Stage IV

In stage IV, the tumor is any size and has become attached to the bone, or cancer has spread to lymph nodes that are not movable or have become ulcerated, or there is distant spread. Stage IV is divided into stages IVA and IVB.

  • In stage IVA, the cancer is attached to the pelvic bone or has spread to lymph nodes in the groin that are not movable or have become ulcerated.
  • In stage IVB, the cancer has spread beyond the pelvis to distant parts of the body.

Vulvar cancer can recur (come back) after it has been treated.

The cancer may come back in the vulva or in other parts of the body.

Treatment Option Overview

Key Points

  • There are different types of treatment for patients with vulvar cancer.
  • The following types of treatment are used:
    • Surgery
    • Radiation therapy
    • Chemotherapy
    • Immunotherapy
  • New types of treatment are being tested in clinical trials.
  • Treatment for vulvar cancer may cause side effects.
  • Patients may want to think about taking part in a clinical trial.
  • Patients can enter clinical trials before, during, or after starting their cancer treatment.
  • Follow-up tests may be needed.

There are different types of treatment for patients with vulvar cancer.

Different types of treatments are available for patients with vulvar cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

The following types of treatment are used:

Surgery

Surgery is the most common treatment for vulvar intraepithelial neoplasia (VIN) and vulvar cancer.

One of the following types of surgery may be done to treat VIN:

  • Separate excision of a lesion: A surgical procedure to remove a lesion of concern.
  • Wide local excision: A surgical procedure to remove the area of skin affected by VIN and some of the normal tissue around it.
  • Laser surgery: A surgical procedure that uses a laser beam (a narrow beam of intense light) as a knife to make bloodless cuts in tissue or to remove a surface lesion such as a tumor.
  • Ultrasound surgical aspiration: A surgical procedure to break the tumor up into small pieces using very fine vibrations. The small pieces of tumor are washed away and removed by suction. This procedure causes less damage to nearby tissue.
  • Skinning vulvectomy: The top layer of vulvar skin where the VIN is found is removed. Skin grafts from other parts of the body may be needed to cover the area where the skin was removed.

The goal of surgery for vulvar cancer is to remove all the cancer without any loss of the woman's sexual function. One of the following types of surgery may be done to treat vulvar cancer:

  • Wide local excision: A surgical procedure to remove the cancer and some of the normal tissue around the cancer.
  • Radical local excision: A surgical procedure to remove the cancer and a large amount of normal tissue around it. Nearby lymph nodes in the groin may also be removed.
  • Vulvectomy: A surgical procedure to remove part or all of the vulva:
  • Pelvic exenteration: A surgical procedure to remove the lower colon, rectum, and bladder. The cervix, vagina, ovaries, and nearby lymph nodes are also removed. Artificial openings (stoma) are made for urine and stool to flow from the body into a collection bag.

After the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy and/or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy.

Radiation therapy

Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. External radiation therapy uses a machine outside the body to send radiation toward area of the body with cancer.

External radiation therapy may also be used as palliative therapy to relieve symptoms and improve quality of life.

Chemotherapy

Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). Topical chemotherapy for vulvar cancer may be applied to the skin in a cream or lotion. The way the chemotherapy is given depends on the type and stage of the cancer being treated.

See Drugs Approved to Treat Vulvar Cancer for more information.

Immunotherapy

Immunotherapy is a treatment that uses the patient's immune system to fight cancer. Substances made by the body or made in a laboratory are used to boost, direct, or restore the body's natural defenses against cancer.

Imiquimod is an immune response modifier used to treat vulvar lesions and is applied to the skin in a cream.

New types of treatment are being tested in clinical trials.

Information about clinical trials is available from the NCI website.

Treatment for vulvar cancer may cause side effects.

For information about side effects caused by treatment for cancer, see our Side Effects page.

Patients may want to think about taking part in a clinical trial.

For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.

Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.

Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.

Patients can enter clinical trials before, during, or after starting their cancer treatment.

Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.

Clinical trials are taking place in many parts of the country. Information about clinical trials supported by NCI can be found on NCI’s clinical trials search webpage. Clinical trials supported by other organizations can be found on the ClinicalTrials.gov website.

Follow-up tests may be needed.

Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.

Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

It is important to have regular follow-up exams to check for recurrent vulvar cancer.

About This PDQ Summary

About PDQ

Physician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.

PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government’s center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.

Purpose of This Summary

This PDQ cancer information summary has current information about the treatment of vulvar cancer. It is meant to inform and help patients, families, and caregivers. It does not give formal guidelines or recommendations for making decisions about health care.

Reviewers and Updates

Editorial Boards write the PDQ cancer information summaries and keep them up to date. These Boards are made up of experts in cancer treatment and other specialties related to cancer. The summaries are reviewed regularly and changes are made when there is new information. The date on each summary ("Updated") is the date of the most recent change.

The information in this patient summary was taken from the health professional version, which is reviewed regularly and updated as needed, by the PDQ Adult Treatment Editorial Board.

Clinical Trial Information

A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.

Clinical trials can be found online at NCI's website. For more information, call the Cancer Information Service (CIS), NCI's contact center, at 1-800-4-CANCER (1-800-422-6237).
