The term VAIN refers to changes that can happen in the skin of the vagina. VAIN is not cancer, and in some women it disappears without treatment. However, if the changes become more severe, there is a chance that cancer may develop after many years, so it's referred to as a pre-cancerous condition.
VAIN can occur in just one area of the vagina, but more often it affects several different areas at once (it’s multifocal). If only one area is affected, it’s most often the upper third of the vagina, towards the neck of the womb (cervix).
Although VAIN used to be rare, it’s now recognised and diagnosed more often. It can affect women of any age, but is more common in women over 50. Occasionally, women may have abnormal changes that affect other areas as well as the vagina, such as the cervix, vulva and anus.
