Vaginal Cancer
What is vaginal cancer?
Vaginal cancer is a disease in which malignant (cancer) cells form in the
vagina.
The vagina is the canal leading from the cervix (the opening of uterus) to
the outside of the body. At birth, a baby passes out of the body through the
vagina (also called the birth canal).
Vaginal cancer is not common. When found in early stages, it can often be
cured. There are two main types of vaginal cancer:
- Squamous cell carcinoma: Cancer that forms in squamous cells, the thin,
flat cells lining the vagina. Squamous cell vaginal cancer spreads slowly and
usually stays near the vagina, but may spread to the lungs and liver. This is
the most common type of vaginal cancer. It is found most often in women aged 60
or older.
- Adenocarcinoma: Cancer that begins in glandular (secretory) cells.
Glandular cells in the lining of the vagina make and release fluids such as
mucus. Adenocarcinoma is more likely than squamous cell cancer to spread to the
lungs and lymph nodes. It is found most often in women aged 30 or younger.
What are causes and risk factors for vaginal cancer?
Age and exposure to the drug DES (diethylstilbestrol) before birth affect a
woman's risk of developing vaginal cancer.
Anything that increases your risk of getting a disease is called a risk
factor. Risk factors for vaginal cancer include the following:
- Being aged 60 or older.
- Being exposed to DES while in the mother's womb.
In the 1950s, the drug DES was given to some pregnant women to prevent
miscarriage (premature birth of a fetus that cannot survive). Women who were
exposed to DES before birth have an increased risk of developing vaginal cancer.
Some of these women develop a rare form of cancer called clear cell
adenocarcinoma.
- Having human papilloma virus (HPV) infection.
- Having a
history of abnormal cells in the cervix or cervical cancer.
