Vaginal cancer is a type of cancer that affects the vaginal tissue. The vagina is the muscular tube that connects the uterus to the outside of the body, and vaginal cancer occurs when abnormal cells grow uncontrollably in the lining of the vagina.
There are two main types of vaginal cancer: squamous cell carcinoma and adenocarcinoma. Squamous cell carcinoma is the most common type of vaginal cancer, and it starts in the squamous cells that line the vagina. Adenocarcinoma, on the other hand, starts in the glandular cells that produce mucus in the vagina.
