What Happens During Cervical Cancer Screening?

Cervical cancer screening is a routine health check designed to find changes in the cervix (the lower part of the uterus) before they turn into cancer. Early detection through screening can prevent cancer or catch it at a stage that’s highly treatable. Here’s what you can expect.

Why Cervical Cancer Screening Matters

Cervical cancer screening helps detect:

• Abnormal cell changes (precancerous lesions)
• High-risk human papillomavirus (HPV) infections
• Early signs of cervical cancer

Guidelines (Massad et al., 2013) recommend starting screening around age 21 and continuing through age 65. Depending on your age, health history, and past results, you may have:

• A Pap test alone
• An HPV test alone
• “Co-testing” (both Pap and HPV tests together)

Before Your Appointment

Preparing can make the experience smoother:

• Schedule wisely: Avoid screening when you have your period.
• Avoid vaginal products: For 24–48 hours beforehand, steer clear of douches, creams, spermicides or lubricants.
• Empty your bladder: A full bladder can make the exam less comfortable.
• Share your history: Let your provider know about any past abnormal tests, HPV infections, pregnancies or surgeries.

What to Expect During the Exam

Cervical cancer screening is usually done as part of a pelvic exam. It takes just a few minutes:

1. Positioning
   • You’ll lie on an exam table with feet in stirrups or footrests.
   • A drape or sheet will cover your lower body for modesty.

2. Speculum insertion
   • The provider gently inserts a speculum (metal or plastic) into the vagina to hold its walls open.
   • You may feel pressure or mild discomfort but not sharp pain.

3. Cell collection
   • Using a soft brush or small spatula, the provider collects cells from the cervix’s surface.
   • If it’s a liquid‐based Pap, the tool is rinsed in a vial of preservative fluid. For a traditional Pap, cells go on a glass slide.
   • If it’s an HPV test only, a similar swab is used to detect high-risk virus types.

4. Removal and cleanup
   • The speculum is removed gently.
   • You’ll have a moment for privacy to get dressed.

Total time: about 5–10 minutes. Most people describe only mild pressure or cramping.

After the Test: Understanding Your Results

Your sample is sent to a lab for analysis. Results usually arrive in 1–3 weeks. Common outcomes:

• Normal
  • No signs of abnormal cells or high-risk HPV.
  • Next screening in 3–5 years (depending on your age and test type).

• ASC-US or LSIL (mild abnormalities)
  • Often linked to HPV.
  • May warrant repeat testing in 6–12 months or direct HPV testing.

• HSIL or ASC-H (more serious changes)
  • Higher chance of precancer.
  • Referral to colposcopy (detailed exam) is common.

• HPV positive, but normal cells
  • Repeat co-testing in 12 months or HPV genotyping to check for types 16/18.

If Your Results Are Abnormal

An abnormal Pap or HPV result does not mean cancer is present. It means closer follow-up is needed:

1. Colposcopy

   • A magnified view of the cervix using a special microscope (colposcope).
   • Acetic acid (vinegar solution) may be applied to highlight abnormal cells.

2. Biopsy

   • Tiny samples of tissue are taken from any suspicious areas.
   • Local anesthesia minimizes discomfort.

3. Endocervical sampling

   • A small brush or curette gathers cells from the cervical canal.

4. Treatment of precancer (if confirmed)

   • LEEP (Loop Electrosurgical Excision Procedure): A thin wire loop removes abnormal tissue.
   • Cryotherapy: Freezes and destroys precancerous cells.
   • Laser therapy: Uses focused light to vaporize abnormal cells.

Most treatments are outpatient, quick, and do not affect fertility.

Tips to Reduce Discomfort

• Breathe deeply during speculum insertion.
• Use a warm speculum if available (some clinics offer this).
• Communicate: Let your provider know if you feel sharp pain.
• Bring a friend for support in the waiting room.

Common Questions

Q: Does cervical cancer screening hurt?
A: Most people feel pressure or mild cramping. Sharp pain is uncommon—speak up if it happens.

Q: How often should I be screened?
A:

• Ages 21–29: Pap test every 3 years.
• Ages 30–65: Pap + HPV co-test every 5 years (or Pap alone every 3 years).
• Over 65 with a good history: May stop screening after discussion with your provider.

Q: Can I have sex before the test?
A: It’s best to abstain for 24–48 hours prior, to avoid affecting results.

When to Seek Medical Advice

Although screening is preventive, you should talk to a doctor if you experience:

• Unusual vaginal bleeding (between periods, after sex or after menopause)
• Persistent pelvic pain
• Unusual discharge

You might also consider doing a free, online symptom check for cervical or gynecologic concerns to guide your next steps.

Final Thoughts

Cervical cancer screening is a straightforward, vital tool in women’s health. It finds early changes before cancer develops, significantly improving outcomes. While the idea of a pelvic exam can feel awkward, the procedure itself is quick and usually well tolerated. Regular screening according to guidelines helps protect your health.

If you have any life-threatening or serious symptoms—or if you’re due (or overdue) for screening—please speak to a doctor as soon as possible. Your healthcare provider can answer questions, discuss vaccines (like HPV vaccination), and set up the right screening schedule for you.
