What is vaginal dysplasia?

Vaginal dysplasia is the abnormal growth of cells within the tissue of the vagina. This is associated with human papillomavirus (HPV) infection and early stage development of vaginal cancer. It is generally detected during routine female exams, which include a pelvic exam and Pap smear. Women who experience discomfort or irregular menstruation may be symptomatic and should seek medical attention. Annual female examinations and responsible sexual practices decrease a woman’s chances of developing this form of dysplasia.

Human papillomavirus is an infection that causes abnormal cell maturation and manifests as either genital warts or lesions. Though it can affect any part of the body, a genital HPV infection commonly occurs in women under the age of 25 who have a weakened immune system. Having multiple sexual partners is also a risk factor, even if a person always uses protection, as HPV can be spread through areas that are not covered by a condom. As HPV often does not cause symptoms, it can be difficult to know whether a person has it, even if he or she practices safe sex. Transmitted through direct sexual contact, vaginal dysplasia associated with HPV can result in the formation of pre-cancerous lesions.

Detected during a Pap smear, HPV-related dysplasia is classified as low- to high-grade, depending on stage of development. Abnormalities classified as low-grade generally subside over time. Serious grades, such as moderate and high, require treatment, which may include surgery to remove the affected cells and tissue. Other treatments may include cryotherapy, which involves the freezing of the affected tissue to eliminate abnormal cells, laser surgery, and electrocautery, which uses a high-frequency electrical current to remove affected cells. It’s rare for dysplasia to develop into cancer; however, a woman who experiences repeated infections has an increased chance of developing vaginal or other gynecologic cancers.

Vaginal cancer is a rare condition resulting from the generation of abnormal cells that do not die as do normal cells during healthy cell production. The numerous cells accumulate in masses, forming tumors, and have the potential to metastasize, or separate and spread to other parts of the body. Women who have vaginal cancer may not exhibit any symptoms, so early detection is key.
