A cancer that begins as a growth of cells on the outer surface area of the female genitals.

Vulvar cancer is most commonly diagnosed in older women. Risks include smoking and exposure to human papillomavirus, also called HPV. An early diagnosis reduces the likelihood that extensive treatment will be needed.

Vulvar cancer commonly forms as a lump or sore on the vulva that often causes itching.

Treatment usually involves surgery to remove the cancer and a small amount of surrounding healthy tissue.
