Vaginal cancer is a rare type of cancer that primarily affects the lining of the vagina. The exact cause remains unclear, but several risk factors have been identified, including human papillomavirus (HPV) infection, which is linked to many cervical and vaginal cancers. Women who have a history of cervical cancer, those who have received radiation therapy to the pelvic area, and individuals with certain genetic conditions, such as Lynch syndrome, are also at increased risk.
