Cancer - Vulva
Multimedia
Definition
Vulvar cancer is cancer that starts in the vulva. Vulvar cancer most often affects the labia, the folds of skin outside the vagina. In some cases, vulvar cancer may start on the clitoris or in glands on the sides of the vagina opening.
Alternative Names
Cancer - perineum
Causes, incidence, and risk factors
Most vulvar cancers begin in skin cells called squamous cells. Other vulvar cancers are:
Adenocarcinoma
Basal cell carcinoma
Melanoma
Sarcoma
Vulvar cancer is relatively rare. Risk factors include:
- Human papilloma virus (HPV, or genital warts) infection in women under age 50
- Chronic skin changes such as lichen sclerosis or squamous hyperplasia in women over age 50
- History of cervical cancer or vaginal cancer
- Smoking
Women with a condition called vulvar intraepithelial neoplasia (VIN) have a greater risk of developing vulvar cancer that spreads. However, most cases of VIN never lead to cancer.

Treatment
Imiquimod 5% cream may be used to treat vulvar intraepithelial neoplasia (VIN).
Treatment involves surgery to remove the cancer cells. If the tumor is large (more than 2 cm) or has grown deeply into the skin, the lymph nodes in the groin area may also be removed.
Radiation, with or without chemotherapy, may be used to treat advanced tumors or vulvar cancer that comes back.
Support Groups
You can ease the stress of illness by joining a support group whose members share common experiences and problems. See cancer - support group.
Expectations (prognosis)
Most women with vulvar cancer who are diagnosed and treated at an early stage do well. However, a woman's outcome depends on:
- The size of the tumor
- The type of vulvar cancer
- Whether the cancer has spread
The cancer commonly comes back at or near the site of the original tumor.
Complications
Complications may include:
Spread of the cancer to other areas of the body
Side effects of radiation, surgery, or chemotherapy
Calling your health care provider
Call your health care provider if you have any of these symptoms for more than 2 weeks:
Skin color change
Sore on the vulva

Prevention
Practicing safe sex may decrease your risk of vulvar cancer. This includes using condoms to protect against sexually transmitted infections.
A vaccine is available to protect against certain forms of HPV infection. The vaccine is approved to prevent cervical cancer and genital warts. It may help prevent other cancers linked to HPV, such as vulvar cancer. The vaccine is given to young girls before they become sexually active, and to adolescents and women up to age 26.
Routine pelvic exams can help diagnose vulvar cancer at an earlier stage. Earlier diagnosis improves your chances that treatment will be successful.
