Vaginal cancer: types, signs, diagnosis, treatment and prevention

Types and characteristics

There are two main histologic types of primary vaginal cancer. Squamous cell carcinoma develops from the thin, flat cells that line most of the vagina. Adenocarcinoma arises from glandular cells and is less common. Other rare types include melanoma and sarcoma. Tumor location (upper, middle, lower third of the vagina) and depth of invasion help determine symptoms and treatment options. For general background on vaginal anatomy see vaginal tissues and structure.

Signs, diagnosis and staging

Symptoms can include abnormal vaginal bleeding, a persistent abnormal discharge, pain during intercourse, a palpable mass, or pelvic pain. Because early disease may be asymptomatic, diagnosis often follows a pelvic examination, colposcopy, and biopsy. Imaging (ultrasound, MRI, CT) and clinical assessment are used to stage disease, which guides therapeutic choices. For clinical overviews and guidance consult authoritative resources: vaginal cancer information.

Risk factors and causes

Risk factors associated with vaginal cancer include persistent infection with high‑risk human papillomavirus (HPV) strains, a history of cervical or vulvar neoplasia, prior pelvic radiation, and certain inherited or environmental influences. Age and smoking are additional contributors. In many cases, a clear single cause cannot be identified and multiple factors interact.

Treatment and prognosis

Treatment depends on tumor type, size, location and stage. Options include surgery (wide local excision or more extensive pelvic procedures), radiation therapy, and sometimes chemotherapy. Early, localized cancers are often treatable with surgery or radiation alone; advanced disease may require combined modalities. Prognosis is better for small, surgically removable tumors and for cancers detected early.

Prevention, screening and notable facts

Primary prevention focuses on HPV vaccination and tobacco cessation. There is no routine screening program specifically for vaginal cancer in the general population; attention to abnormal vaginal bleeding and regular gynecologic exams are important. Distinct from metastatic involvement, primary vaginal cancer is rare; clinicians carefully distinguish primary tumors from lesions that represent spread from cervix, vulva, bladder or rectum because management differs substantially.
