Most vaginal cancers occur when another cancer, such as cervical, vulvar, or endometrial cancer, spreads. This is called secondary vaginal cancer.

Cancer that starts in the vagina is called primary vaginal cancer. This type of cancer is rare. Most primary vaginal cancers start in skin-like cells called squamous cells. This cancer is known as squamous cell carcinoma. The other types include:

• Adenocarcinoma
• Melanoma
• Sarcoma

The cause of squamous cell carcinoma of the vagina is unknown. But a history of cervical cancer is common in women with squamous cell carcinoma of the vagina. So it may be associated with human papilloma virus (HPV) infection.

Most women with squamous cell cancer of the vagina are over 50.

Adenocarcinoma of the vagina tends to affect younger women. The average age at which this cancer is diagnosed is 19. Women whose mothers took the medicine diethylstilbestrol (DES) to prevent miscarriages during the first 3 months of pregnancy are more likely to develop vaginal adenocarcinoma.

Sarcoma of the vagina is a rare cancer that mainly occurs in infancy and early childhood.

Symptoms of vaginal cancer can include any of the following:

• Bleeding after having sex
• Painless vaginal bleeding and discharge not due to a normal period
• Pain in the pelvis or vagina

Some women have no symptoms.

In women with no symptoms, the cancer may be found during a routine pelvic exam and Pap test.

Other tests to diagnose vaginal cancer include:

• Biopsy
• Colposcopy

Other tests that may be done to check if the cancer has spread include:

• Chest x-ray
• CT scan and MRI of the abdomen and pelvis
• PET scan

Other tests that may be done to know the stage of the vaginal cancer include:

• Cystoscopy
• Barium enema
• Intravenous urography (x-ray of kidney, ureters and bladder using contrast material)

Treatment of vaginal cancer depends on:

• The type of cancer
• How far the disease has spread

Surgery is sometimes used if the cancer is small and located at the upper part of the vagina. Most women are treated with radiation. If the tumor is cervical cancer that has spread to the vagina, radiation and chemotherapy are both given.

Sarcoma may be treated with a combination of chemotherapy, surgery, and radiation.

You can ease the stress of illness by joining a support group whose members share common experiences and problems.

The outlook for women with vaginal cancer depends on the size and the stage of disease and the specific type of tumor.

Vaginal cancer may spread to other areas of the body. Complications can occur from radiation, surgery, and chemotherapy.

Contact your health care provider for an appointment if:

• You notice bleeding after sex
• You have persistent vaginal bleeding or discharge

There are no definite ways to prevent this cancer.

The HPV vaccine is approved to help prevent cervical cancer. This vaccine may also decrease the risk of getting some other HPV-associated cancers, such as vaginal cancer. You can increase your chance of early detection by getting regular pelvic examinations and Pap smears.
