What lowers your risk
- Get the HPV vaccine if you are eligible — it prevents infection with the high-risk types most linked to vaginal cancer
- Keep up with cervical screening on schedule; it does not screen the vagina directly, but it catches HPV and cervical changes early and prompts closer follow-up
- Do not smoke — smoking more than doubles a woman's risk of vaginal cancer
- Use condoms and consider your number of lifetime partners; both lower HPV exposure, though condoms do not remove the risk entirely
- If you were exposed to DES before birth (given to pregnant women from the 1940s to 1971), tell your doctor — you may need closer gynecologic follow-up
- If you are living with HIV, stay in care; a well-controlled immune system clears HPV more effectively
Who is at higher risk
- Persistent infection with high-risk HPV, especially types 16 and 18
- Older age — almost half of squamous cell cases occur in women 70 or older
- A personal history of cervical cancer or cervical pre-cancer, which share the same risk factors
- DES exposure before birth, raising the risk of a rare clear-cell type (still uncommon, roughly 1 in 1,000 exposed women)
- Smoking
- Living with HIV
What screening exists, honestly
There is no dedicated screening test for vaginal cancer the way there is for cervical or breast cancer. Routine cervical screening — Pap and/or high-risk HPV testing, every three years with Pap alone from 21 to 65, or every five years with HPV testing from 30 to 65 — sometimes picks up abnormal cells or HPV that also signal risk in the vagina, and the pelvic exam at that visit can reveal visible changes (PMID 30140884).
But most vaginal cancers are found because a woman noticed something and had it checked, not through screening. That is why the list below matters more here than on most pages. If you have vaginal adenosis or DES exposure, ask about closer follow-up.
Signs worth reporting promptly
- Vaginal bleeding that is not normal for you — after menopause, between periods, or after sex
- Vaginal discharge that is new or different
- A lump or mass you can feel
- Pelvic pain, particularly with urination or sex
- Blood in urine or stool, or new constipation, which can happen if a tumor presses on nearby organs
What treatment involves
Radiation is the treatment used most often for vaginal cancer, frequently combined with low-dose chemotherapy that makes the radiation work better. Surgery — removing the tumor, sometimes part or all of the vagina, and possibly nearby lymph nodes — is used mainly for early, small, localized tumors, or when radiation is not an option.
Most patients receiving radiation get a combination: external beam radiation therapy aimed at the pelvis from outside the body over several weeks, and brachytherapy, where the radiation source is placed directly in or beside the vagina. For very early, thin tumors, brachytherapy alone may be enough. For anything larger or deeper, external beam comes first to shrink the tumor and treat surrounding lymph nodes, followed by a brachytherapy boost to the tumor bed.
Chemotherapy is usually given at low doses alongside radiation rather than on its own — this is called chemoradiation.
Radiation to this area can cause vaginal dryness, narrowing and pain with sex. Ask about moisturizers, dilators and pelvic floor support early. These are a normal, expected part of the plan, not an awkward afterthought, and raising it first is something your team should be doing for you.
Questions to ask your care team
- What stage is my cancer, and how does that change my options?
- Will my treatment be radiation, surgery, chemotherapy, or a combination — and why that one?
- If I need radiation, will I have both external beam and brachytherapy, and what does each appointment involve?
- What can be done to prevent or manage vaginal dryness and narrowing?
- Will treatment affect my ability to have sex, and what support is available?
- What does follow-up look like after treatment ends?
Where these numbers come from
HPV attribution: Centers for Disease Control and Prevention. Screening intervals: US Preventive Services Task Force, JAMA 2018 (PMID 30140884). Risk factors, symptoms and treatment: American Cancer Society. We used the CDC's combined "about 70%" figure for vaginal and vulvar cancers rather than the separate percentages circulating in secondary sources, which we could not verify.
