Vaginal cancer can start in the vagina itself (primary vaginal cancer) or spread into the vagina from another part of the body (secondary vaginal cancer).
There are two main types of primary vaginal cancer, and they are named after the cells from which they develop:
Other very rare types of vaginal cancer include melanoma, small cell carcinoma, sarcoma, and lymphoma.
Secondary cancers in the vagina are more common than primary vaginal cancer, and usually come from the neck of the womb (cervix), the lining of the womb (endometrium) or from nearby organs such as the bladder or bowel.
