Vaginal tumors
Definition
A vaginal tumor is an abnormal growth of tissue in the vagina, a female reproductive organ.
Alternative Names
Vaginal cancer; Cancer - vagina; Tumor - vaginal
Causes
Most cancerous vaginal tumors occur when another cancer, such as cervical or endometrial cancer, spreads. This is called secondary vaginal cancer.
Primary vaginal cancer is very rare. Most primary vaginal cancers start in skin cells called squamous cells. The rest are adenocarcinoma (6%), melanoma (3%), and sarcoma (3%).
The cause of squamous cell carcinoma of the vagina is unknown. However, up to 30% of patients have had cervical cancer.
About 75% of patients with squamous cell cancer of the vagina are over 50. Adenocarcinomas of the vagina more commonly affect younger women. The average age at which adenocarcinoma of the vagina is diagnosed is 19.
Women whose mothers took diethylstilbestrol (DES, which was prescribed to prevent miscarriages) during the first 3 months of pregnancy are at increased risk for developing adenocarcinoma.
Sarcoma botryoides of the vagina is a rare type of cancer that mainly occurs in infancy and early childhood.
Symptoms
- Bleeding after sexual intercourse
- Painless vaginal bleeding and discharge
- Pain in the pelvis or vagina
About 5 - 10% of patients have no symptoms.
Exams and Tests
In patients with no symptoms, the cancer may be found during a routine pelvic examination and Pap smear.
Other tests to diagnose vaginal tumors include:
Other tests that may be done include:
- Chest x-ray
- CT scan of the abdomen and pelvis
Treatment
Treatment of vaginal cancer depends on the type of cancer, and how far the disease has spread.
Surgery is sometimes used to remove the cancer, but most patients are treated with radiation. If the tumor is cervical cancer that has spread to the vagina, then radiation and chemotherapy are both given.
Sarcoma botryoides may be treated with a combination of chemotherapy, surgery, and radiation.
Support Groups
You can ease the stress of illness by joining a support group whose members share common experiences and problems. You can find these support groups by searching the Internet or contacting the American Cancer Society.
Outlook (Prognosis)
How well patients with vaginal cancer do depends on the stage of disease and the specific type of tumor.
Possible Complications
Vaginal cancer may spread to other areas of the body. Complications can occur from radiation, surgery, and chemotherapy.
When to Contact a Medical Professional
Call for an appointment with your health care provider if you notice bleeding after intercourse or have persistent vaginal bleeding or discharge.
Prevention
There are no definite ways to prevent this cancer. You can increase your chances of early detection by getting regular yearly pelvic examinations and Pap smears.
