Screening & Gynecologic Cancer
Cervical Cancer Symptoms: Early Signs, Causes and Prevention
Early cervical cancer usually causes no symptoms at all, which is exactly why screening matters. When symptoms show up, the most common are bleeding after sex, bleeding between periods or after menopause, and unusual watery, bloody or bad-smelling discharge. Nearly all cervical cancers come from long-lasting HPV infection, and most can be prevented with vaccination and screening.
If you're reading this because of a symptom, take a breath. Every symptom on this page has far more common, non-cancer causes. But each one deserves an exam, and you shouldn't talk yourself out of booking it.
What are the early signs of cervical cancer?
Precancer and very early cervical cancer rarely cause anything you'd notice. Most early cases are found on a routine Pap or HPV test, not because someone felt something was off.
As a cancer grows, possible symptoms include:
- Bleeding after vaginal sex
- Bleeding or spotting between periods
- Periods that are heavier or longer than usual
- Any bleeding after menopause
- Watery, pink, bloody or bad-smelling discharge
- Pain during sex
- Pelvic pain that doesn't go away
Signs of more advanced cervical cancer
When cancer spreads beyond the cervix, it can cause:
- Pain in the lower back, side or legs
- Swelling in one or both legs
- Trouble urinating or blood in the urine
- Bowel changes or bleeding from the rectum
- Tiredness, weight loss and loss of appetite
Is it cancer, or something else?
Here's how these symptoms line up against the far more common explanations.
| Symptom | Common non-cancer causes | When to get checked |
|---|---|---|
| Bleeding after sex | Cervical inflammation, polyps, infection, vaginal dryness | Any time it happens, especially if it repeats |
| Bleeding between periods | Hormonal birth control, ovulation, polyps, fibroids | If new, ongoing or unexplained |
| Bleeding after menopause | Vaginal atrophy, polyps | Always |
| Unusual discharge | Bacterial vaginosis, yeast, STIs | If it doesn't clear with treatment or is bloody |
| Pelvic pain | Menstrual cramps, cysts, endometriosis, infection | If persistent or severe |
Only an exam can tell the difference. Don't assume a symptom is harmless, and don't assume it's cancer either.
What causes cervical cancer?
Persistent infection with high-risk HPV causes nearly all cervical cancers. HPV 16 and HPV 18 cause most of them.
HPV is extremely common; most sexually active people get it at some point, and most infections clear on their own within a couple of years. Cancer develops only when an infection hangs on for years and slowly changes the cells. That usually takes 10 years or more.
A question people are often embarrassed to ask: "Does HPV mean my partner cheated?" No. HPV can stay quiet for years, so a positive test today says nothing reliable about when or from whom it came.
Things that make a persistent infection and cancer more likely:
- Smoking
- HIV or another condition that weakens the immune system
- Long-term immune-suppressing medicines, such as after an organ transplant
- Not being screened, or missing follow-up after an abnormal result
- Not being vaccinated against HPV
- Long-term use of birth control pills (the risk falls again after stopping)
- Having had several full-term pregnancies
Many people diagnosed with cervical cancer in the U.S. hadn't been screened recently. Missed follow-up after an abnormal result is the other big gap.
Can cervical cancer be prevented?
Yes. It's one of the most preventable cancers there is.
HPV vaccination
The vaccine prevents infection with the HPV types behind most cervical cancers. It's routinely recommended through age 26, and adults up to 45 can talk it over with a clinician. See our guide to the HPV vaccine for adults.
Regular screening
Screening finds precancer, which can be treated before it ever turns into cancer. For people at average risk:
- Ages 21 to 29: Pap test every 3 years
- Ages 30 to 65: HPV test every 5 years, co-test every 5 years, or Pap every 3 years
The test itself takes a minute or two: a speculum, a quick brush of the cervix, some pressure. Results usually come back in a week or two. Our guide to how often you need a Pap smear covers the details.
Follow-up and treatment
If a result comes back abnormal, keep every follow-up appointment. Precancer is usually treated with a quick office procedure such as a LEEP.
Other steps that help
- Quit smoking
- Use condoms, which lower HPV spread
- Keep HIV and other immune conditions well managed
How is cervical cancer diagnosed?
If your clinician suspects cervical cancer, next steps may include:
- Pelvic exam and a Pap or HPV test
- Colposcopy with biopsy, a closer look at the cervix with a magnifying scope. See what to expect at a colposcopy.
- Cone biopsy to remove a larger sample if needed
- Imaging, such as MRI, CT or PET scans, to check whether cancer has spread
Cervical cancer is staged from 1 to 4. Stage 1 is limited to the cervix. Higher stages have spread to nearby tissue, lymph nodes or other organs.
How is cervical cancer treated?
Treatment depends on the stage, your overall health and whether you want future pregnancies.
- Very early cancer: cone biopsy or hysterectomy. Some people who want to keep their fertility may be candidates for a trachelectomy, which removes the cervix but keeps the uterus.
- Early-stage cancer: radical hysterectomy, or radiation with chemotherapy
- Locally advanced cancer: usually radiation combined with chemotherapy
- Advanced or recurrent cancer: chemotherapy, immunotherapy and targeted therapy
Care is usually led by a gynecologic oncologist, with radiation and medical oncologists on the team. In New York, gynecologic oncologists practice at major academic and public hospitals across the city, Long Island and Westchester, so ask your gynecologist for a direct referral rather than starting from scratch.
Can you get cervical cancer after a hysterectomy?
If your cervix was removed for a non-cancer reason and you never had high-grade precancer, your risk is extremely low and you usually don't need screening. If your cervix was left in place, you can still get cervical cancer and should keep screening. People who had a hysterectomy for precancer or cancer may need ongoing vaginal testing. Not sure what was removed? Your operative report will say, and your surgeon's office can send it.
When to see a doctor
Book an appointment with your gynecologist or primary care clinician if you have:
- Bleeding after sex, even once, if it's new for you
- Bleeding between periods that your birth control doesn't explain
- Any bleeding after menopause
- Watery, bloody or bad-smelling discharge
- Pelvic pain or pain during sex that doesn't go away
- An overdue Pap or HPV test, or a follow-up you missed after an abnormal result
No insurance? Uninsured New Yorkers may qualify for free cervical cancer screening through the New York State Cancer Services Program. To find a provider, search our directory or browse gynecologists in Queens and other boroughs.
Frequently asked questions
What are the first signs of cervical cancer?
Early cervical cancer usually causes no symptoms. When symptoms do appear, the most common are bleeding after sex, bleeding between periods or after menopause, and unusual watery or bloody discharge.
What causes cervical cancer?
Nearly all cervical cancers are caused by long-lasting infection with high-risk types of HPV. Smoking and a weakened immune system make it harder for the body to clear HPV.
Can cervical cancer be prevented?
Yes, in most cases. HPV vaccination prevents most of the infections that cause it, and regular screening finds precancer that can be treated before it ever becomes cancer.
How fast does cervical cancer develop?
It usually takes many years, often 10 or more, for a persistent HPV infection to become cancer. That long window is why screening every 3 to 5 years works.
Is cervical cancer curable?
When it's found early, cervical cancer is often curable. Treatment depends on the stage and may include surgery, radiation and chemotherapy.
