Alternate Names : Cancer – perineum
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.
Overview, Causes, & 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.
