Vaginal cancer is a rare disease that develops in the tissues of the vagina. Despite its low incidence, vaginal cancer has many types. According to the American Cancer Society, about 1 in every 1,100 women will develop vaginal cancer in her lifetime, with an estimated 6,230 women in the United States expected to be diagnosed with the disease in 2020.
The vast majority of vaginal cancers are squamous cell carcinomas. They form in the squamous cells that make up the epithelial lining of the vagina. If left untreated, they can grow through the vaginal wall and spread to nearby tissues and other parts of the body, most frequently the lungs, the liver and the bones.
