A vaginal tumor is an abnormal growth of tissue in the vagina, a female reproductive organ.

Most cancerous vaginal tumors are the result of the spread of a different cancer, such as cervical or endometrial cancer. This is called secondary vaginal cancer.

Primary vaginal cancer is very rare. Most primary vaginal cancers start in skin cells called squamous cells. The remainder is grouped as adenocarcinoma (6%), melanoma (3%), and sarcoma (3%).

The cause of squamous cell carcinoma of the vagina is unknown, but up to 30% of patients have a prior history of 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 of diagnosis for adenocarcinoma of the vagina is 19.

Women whose mothers took diethylstilbestrol (DES) 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.

• Painless vaginal bleeding and discharge
• Bleeding after sexual intercourse
• Pelvic or vaginal pain

About 5 - 10% of patients have no symptoms and have their cancer detected at the time of routine pelvic examination and Pap smear.

Tests to diagnose vaginal tumors include:

• Pelvic examination
• Pap smear
• Biopsy

If a Pap smear is abnormal, but problems with the vagina can not be seen during a pelvic exam, a colposcopy may be done.

Other tests that may be done include:

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