Overview
Vulvar cancer, a malignant invasive growth in the vulva, accounts for about 4 % of all gynecological cancers and typically affects women in later life. It is estimated that in the United States in 2006 about 3,740 new cases will be diagnosed and about 880 women will die as a result of vulvar cancer.[1] Vulvar carcinoma is separated from vulvar intraepithelial neoplasia (VIN), a non-invasive lesion of the epithelium that can progress via carcinoma-in-situ to squamous cell cancer, and from Paget disease of the vulva.
