The vagina is the passageway through which fluid passes out of the body during menstrual periods. It is also called the birth canal. The vagina connects the cervix (the opening of the womb, or uterus) and the vulva (the external genitalia).
Cancer of the vagina, a rare kind of cancer in women, is a disease in which malignant (cancer) cells are found in the tissues of the vagina. According to the American Cancer Society, about 2,890 cases of vaginal cancer will be diagnosed in the U.S. in 2013.
There are several types of cancer of the vagina. The 2 most common are:
Squamous cell cancer (squamous carcinoma):
Squamous carcinoma is most often found in women older than age 60, and accounts for about 70% of all vaginal cancers.
Adenocarcinoma is more often found in women older than 50 and accounts for about 15% of all vaginal cancers.
A rare form of cancer called clear cell adenocarcinoma results from the use of the drug DES (diethylstilbestrol) given to pregnant women between 1940 and 1971 to keep them from miscarrying. It occurs most often in the daughters of the women who took DES.
Other, less common types of cancer that can be found in the vagina include:
Cancers that begin in other organs (such as the cervix and rectum) and spread to the vagina
The following have been suggested as risk factors for vaginal cancer:
Age. Almost half of cases are in women age 70 or older.
Exposure to diethylstilbestrol (DES) as a fetus (mother took DES during pregnancy)
History of cervical cancer
History of cervical precancerous conditions
Human papillomavirus (HPV) infection
The following are the most common symptoms of vaginal cancer. However, each individual may experience symptoms differently. Symptoms may include:
Bleeding or discharge not related to menstrual periods
Difficult or painful urination
Pain during intercourse
Pain in the pelvic area
A mass that can be felt
Even if a woman has had a hysterectomy, she still has a chance of developing vaginal cancer. The symptoms of vaginal cancer may resemble other conditions or medical problems. Consult a doctor for diagnosis.
There are several tests used to diagnose vaginal cancer, including:
Pelvic examination of the vagina, and other organs in the pelvis. This is done to check for tumors, lumps, or masses.
Colposcopy. A procedure that uses an instrument with magnifying lenses, called a colposcope, to examine the cervix and vagina for abnormalities. If abnormal tissue is found, a biopsy is usually performed (this is called a colposcopic biopsy).
Pap test (also called Pap smear). A test that involves microscopic examination of cells collected from the cervix, used to detect changes that may be cancer or may lead to cancer, and to diagnose noncancerous conditions, such as infection or inflammation.
Computed tomography scan (CT or CAT scan). A diagnostic imaging procedure using a combination of X-rays and computer technology to produce horizontal, or axial, images (often called slices) of the body. A CT scan shows detailed images of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general X-rays.
Magnetic resonance imaging (MRI). A diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body.
Positron emission tomography (PET) scan. Radioactive-tagged glucose (sugar) is injected into the bloodstream. Tissues that use the glucose more than most normal tissues (such as tumors) can be detected by a scanning machine. PET scans can be used to find small tumors or to check if treatment for a known tumor is working.
Biopsy. A procedure in which tissue samples are removed from the vagina for examination under a microscope; to determine if cancer or other abnormal cells are present. The diagnosis of cancer is confirmed only by a biopsy.
Specific treatment for vaginal cancer will be determined by your doctor based on:
Your overall health and medical history
Extent of the disease
Your tolerance for specific medications, procedures, or therapies
Expectations for the course of the disease
Your opinion or preference
Generally, there are 3 kinds of treatment available for patients with cancerous or precancerous conditions of the vagina:
Laser surgery to remove the cancer, including LEEP (loop electroexcision procedure)
Local excision to remove the cancer
Vaginectomy to remove all or part of the vagina
