Pap Smear Test

Overview

A Pap smear, also known as a Pap test or cervical cytology, is a medical procedure in which a healthcare provider gathers a sample of cells from the cervix. The main purpose is to check for abnormal cell changes that may signal cervical cancer or could develop into cancer later.

This screening is part of routine health care for many individuals and allows for early treatment, which can prevent or effectively manage most cases of cervical cancer.

Purpose of the Test

Healthcare providers use a Pap test to find early changes in the cervix that could lead to cervical cancer. The test helps detect abnormal cells before they turn into cancer, improving chances of treatment.

Providers focus screening on people with a cervix, as they are at risk for cervical cancer. Most often, the test is done along with a pelvic exam. In many cases, a test for the human papillomavirus (HPV), which causes most cervical cancers, is performed at the same time.

Main reasons providers perform the Pap test:

  • Find early signs of cervical cancer before symptoms appear.
  • Check for abnormal or unusual cervical cells.
  • Screen for HPV, which is a leading cause of cervical cancer.
  • Guide follow-up on abnormal findings or previous problems.

Screening guidelines vary by age and risk level and may change over time.

Age Group Screening Recommendations
21-29 Pap test every 3 years.
30+ Pap test with HPV test every 5 years (co-testing) or HPV test alone every 5 years.
65+ May stop screening if past tests were normal, after talking with a healthcare professional.

For those who have had a total hysterectomy (removal of the uterus and cervix) for reasons not related to cancer, Pap tests may not be needed anymore. Discussing medical history with a provider will help decide what is right. Some people may need more frequent testing, such as those who:

  • Had cervical cancer or precancerous cells in the past
  • Were exposed to diethylstilbestrol (DES) before birth
  • Are living with HIV
  • Have a weakened immune system

Choosing when to start and how often to repeat screening is a personal decision best made together with a healthcare professional.

Possible Concerns

While Pap smears help find early signs of cervical cancer, there are some risks and drawbacks. Sometimes, the test does not collect enough cells or misses abnormal ones. In rare cases, blood or infection covers concerning cells, making them hard to spot.

Using vaginal creams, douching, or certain medicines close to testing time may also reduce detection. Some people feel slight discomfort or inflammation during the test. Rarely, mild bleeding may happen.

If the result shows possible problems, extra tests may be needed, such as a colposcopy, biopsy, or procedures like conization. In some cases, Pap smears may no longer be necessary after a hysterectomy, depending on the reason for surgery.

Common Risks Table

Risk Factor Example or Details
Discomfort Mild pain during exam
Inflammation Redness, mild swelling
Extra diagnostic tests Biopsy, colposcopy, conization
False results Missed abnormal cells

Getting Ready for Your Test

Before a Pap smear, patients should follow certain steps to help the gynecologist get the best results. Avoid intercourse, vaginal creams, lubricants, or douching for two days beforehand. These activities can make it harder for the test to find any abnormal cells.

It’s also best to not schedule the test during a menstrual period. However, if there is unexpected vaginal bleeding not from a regular period, the test should not be delayed. Checklist to prepare:

  • Skip intercourse for 48 hours
  • Don’t use vaginal products
  • Time the test when not on your period

If there are any questions or unique concerns, talking with a healthcare provider can help.

What to Expect

How the Exam Is Done

A healthcare provider performs the Pap test in a clinic or doctor’s office. The person will be asked to remove clothing from the waist down or use a gown for privacy. They will then lie on an exam table with their knees bent and feet placed in stirrups.

The provider gently places a tool called a speculum into the vagina to open the vaginal walls and view the cervix. There may be some mild pressure or cramping, but it should not be painful.

Next, the provider uses a soft brush and a flat spatula to collect a small sample of cells from the cervix. This part of the pelvic exam is quick and usually does not hurt. Sometimes, there may be a small amount of light bleeding afterward.

The provider places the collected cells into a special liquid and sends them to a lab, where technicians check for any abnormal changes.

Step Description
Undressing Waist down or using a gown
Position Lying on back, knees bent, feet in stirrups
Speculum Use Placed in vagina to view cervix, may cause mild pressure or cramping
Cell Collection Small brush and spatula used, usually not painful, slight bleeding possible
Lab Analysis Cervical cells sent to lab for examination

What Happens Next

After the Pap test, people can return to their normal routine. There are no restrictions after the exam. Ask the healthcare provider when the test results will be ready. If any unusual symptoms like heavy bleeding or severe pain occur, contact the clinic.

Test Outcome Details

No Signs of Abnormalities

If the result shows only normal cervical cells, this is often described as “negative for abnormal cells.” In most cases, this means the cervix is healthy.

Common features of negative results:

  • No cancer or pre-cancers found
  • No abnormal or precancerous cells seen
  • No extra follow-up needed until the usual interval
  • Patient receives reassurance of healthy cervical cells
Result Cells Found Next Steps
Negative Normal Routine follow-up

Results That Need More Attention

Sometimes the test results are not clear. This is sometimes called an “uncertain” or “borderline” result. Possible causes include inflammation, infection, or problems during cell collection. The provider may suggest a repeat Pap test or additional testing.

Signs of Unclear Results

  • Cells do not look normal, but are not definitely abnormal.
  • Not enough cells to make a clear decision.
Situation Possible Recommendation
Unclear cell changes Repeat test or HPV testing

Findings That Indicate Cell Changes

A positive result appears when the Pap smear shows cell changes that may need closer monitoring. A positive test does not always mean cancer is present. Many types of positive results can appear:

  • Atypical Squamous Cells of Undetermined Significance (ASC-US): These squamous cells look different than usual, but it is not certain what caused the change. Often, an HPV test follows.
    • If HPV is not found, the risk is usually low.
    • If high-risk HPV is present, further testing may be needed.
  • Squamous Intraepithelial Lesion (SIL): These changes might mean the cells are precancerous.
    • Low-grade SIL: Usually related to HPV; often clears up on its own.
    • High-grade SIL: Higher risk for becoming precancer if left untreated; may need more tests or treatment.
  • Atypical Glandular Cells: Glandular cells are another type in the cervix. Unusual changes in these cells may need more tests to check for problems in the cervix or uterus.

  • Squamous Cell Cancer or Adenocarcinoma Cells: Rarely, tests may find cells that strongly suggest the presence of cancer. If these cells are found, fast follow-up and more detailed tests will be needed.

Follow-up steps may include:

  • HPV testing
  • Colposcopy (exam using a special microscope)
  • Biopsy or further investigations

Quick Reference Table

Result Type Meaning Follow-up Action
ASC-US Mild, unclear changes HPV testing, maybe repeat test
SIL (Low-grade) Possible mild precancer May resolve, repeat soon
SIL (High-grade) Possible serious precancer More tests, possible treatment
Atypical glandular Unusual glandular cells Further studies needed
Cancer cells found Very likely cancer Immediate further testing
