Vulvar cancer

Vulvar malignant tumors are mainly primary, accounting for about 4% of female genital tumors and 1% to 2% of women's systemic tumors. The vast majority of vulvar cancers are squamous epithelial cancers, accounting for about 95% of vulvar malignancies. The average age of onset is 50 to 60 years old. Adenocarcinoma is rare. Sometimes vulvar cancer is confined to the epithelium, and spreading in the epithelium is called carcinoma in situ, also known as vulvar epithelial cancer. There are two types of epithelial cancer: ① squamous carcinoma in situ (also known as Bowen's disease); ② eczema-like intraepithelial Cancer (also known as Paget's disease). There are also basal cell carcinomas and malignant melanomas.
