Vaginal cancer is a rare malignancy arising from vaginal tissue and is most common in older women. Approximately 85% are squamous cell carcinomas, followed by adenocarcinoma, melanoma, and other types. Early-stage disease may be asymptomatic, whereas advanced disease can invade adjacent organs.
1. Squamous cell carcinoma
The most common type (>85%), arising from vaginal squamous epithelium, and is more frequently located in the upper vagina.
2. Adenocarcinoma
Less common, including subtypes such as clear cell adenocarcinoma and endometrioid adenocarcinoma.
3. Malignant melanoma
Rare but highly aggressive, can occur in any vaginal location, and is associated with poor prognosis.
4. Embryonal rhabdomyosarcoma
More common in children, highly malignant, and requires multimodal therapy.
5. Leiomyosarcoma
Arises from vaginal smooth muscle and is rare, with malignant biological behavior.
6. Classification by growth pattern
Includes exophytic tumors (cauliflower-like growth into the lumen) and infiltrative tumors (deep stromal invasion).
7. Classification by anatomic location
Classified as upper-, middle-, or lower-vaginal cancers, which influences treatment strategy selection.
1. HPV infection
High-risk human papillomavirus infection is the major risk factor for vaginal cancer.
2. Age
Most commonly affects women older than 60 years, with increasing incidence with age.
3. Vaginal adenosis
Associated with in utero exposure to diethylstilbestrol, increasing the risk of clear cell carcinoma.
4. History of cervical cancer
Prior cervical cancer or cervical precancer increases the risk of vaginal cancer.
5. Immunosuppression
Chronic immunosuppression, such as in organ transplant recipients, increases risk.
6. Smoking
Smoking is associated with multiple gynecologic malignancies, including vaginal cancer.
7. History of pelvic radiotherapy
Prior pelvic irradiation may increase the risk of vaginal cancer.
8. Chronic irritation
Long-term use of pessaries and other chronic irritation may be associated with disease development.
1. HPV vaccination
HPV vaccination in eligible females prevents infection with oncogenic HPV types and reduces vaginal cancer risk.
2. Regular gynecologic examinations
Annual gynecologic examinations and cervical cytology facilitate early detection of precancerous lesions and early tumors.
3. Healthy lifestyle
Balanced diet and regular exercise, and avoidance of smoking, reduce the risk of multiple gynecologic cancers.
4. Safer sexual practices
Condom use reduces HPV transmission, and limiting the number of sexual partners supports reproductive health.
5. Symptom awareness
Understanding vaginal cancer symptoms and seeking prompt care for abnormal bleeding or discharge helps avoid delayed diagnosis.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that vaginal cancer threatens women’s health and that early symptoms may be overlooked. Strengthening prevention is essential, including HPV vaccination and regular gynecologic examinations. Prompt medical evaluation for abnormal symptoms and early standardized treatment can improve prognosis. MDT-based individualized strategies can enhance therapeutic outcomes while preserving organ function.
