|Layers of vaginal tissue|
It's not clear what causes vaginal cancer. In general, cancer begins when healthy cells acquire a genetic mutation that turns normal cells into abnormal cells.
Healthy cells grow and multiply at a set rate, eventually dying at a set time. Cancer cells grow and multiply out of control, and they don't die. The accumulating abnormal cells form a mass (tumor).
Cancer cells invade nearby tissues and can break off from an initial tumor to spread elsewhere in the body (metastasize).
Types of vaginal cancer
Vaginal cancer is divided into different types based on the type of cell where the cancer began. Vaginal cancer types include:
- Vaginal squamous cell carcinoma, which begins in the thin, flat cells (squamous cells) that line the surface of the vagina, is the most common type
- Vaginal adenocarcinoma, which begins in the glandular cells on the surface of your vagina
- Vaginal melanoma, which develops in the pigment-producing cells (melanocytes) of your vagina
- Vaginal sarcoma, which develops in the connective tissue cells or muscles cells in the walls of your vagina
