What is Vaginal Cancer ?
Vaginal cancer is one of the rare kind of cancer in women, accounting for around two per cent of cases. Women aged over 50 years are most commonly affected. The vagina is part of the female reproductive system. This muscular canal is around 7.5cm long and extends from the neck of the uterus (cervix) to the external genitals (vulva).
Many cancers involving the vagina have actually spread from adjacent tissues, usually from the uterus (womb) or cervix (neck of the womb).
There are many different types of cancer of the vagina: squamous cell cancer (squamous carcinoma), adenocarcinoma, malignant melanomas, and sarcomas.
About 95 per cent of cancers that start in the vagina are squamous cell carcinomas, which means the cancer originated from the skin cells.
Causes of Vaginal Cancer
It is not known exactly what causes primary vaginal cancer. However, women whose mothers took the hormonal drug diethylstilbestrol (DES) during pregnancy to boost oestrogen levels (to prevent miscarriage) are at higher risk of developing a rare type of vaginal cancer called clear cell carcinoma. Only 1 in 1000 women whose mothers took DES go on to develop cancer of the vagina.
There may also be a link between human papilloma viruses (HPV) and all cancers of the reproductive organs, including the vagina. HPV can be transmitted through sexual contact.
Signs & Symptoms of Vaginal Cancer
Some vaginal cancers have no symptoms in their early stages, and only cause symptoms once they have invaded other parts of the body. They may be found through an abnormal pap smear. Some of the symptoms of vaginal cancer can include:
Please keep in mind that these symptoms are also symptoms of many other illnesses. Please see a healthcare provider if you are experiencing any of these symptoms or anything that is abnormal for you.
Your doctor will ask about your symptoms and medical history, and perform a physical exam, including a pelvic exam. You may be referred to a doctor who specializes in women’s health (a gynecologist).
Tests may include:
No certain preventative measures are known.
While a Pap smear is an effective screening tool for cervical cancer, it cannot be relied upon to detect vaginal cancer. However, regular gynecologic examinations may reduce the mortality from vaginal cancer by providing your physician with the opportunity to detect it earlier rather than later. Moreover, informing your physician that you may have been exposed to DES in the womb should induce him or her to provide even closer surveillance.
