What Is a Pap Smear?: Meaning, Test Results & Preparations

What Is a Pap Smear?

A Pap smear, also known as a Pap test, is a medical examination performed by a doctor to screen for cervical cancer in women. Additionally, it can detect abnormalities in cervical cells that could potentially develop into cancer over time.

Why Is a Pap Smear Performed?
The purpose of a Pap smear is to detect cervical cell changes before they progress to cancerous stages. Early detection of cancer provides the greatest opportunity for successful treatment. Conversely, identifying cell abnormalities promptly can aid in preventing the development of cancer.

For individuals aged 21 to 65, regular Pap smears are recommended. The frequency of testing depends on individual health factors and any history of abnormal Pap smears.

How Often Should I Undergo a Pap Smear?
Routine Pap smears are advised every three years for individuals between the ages of 21 and 65. Alternatively, from the age of 30 onwards, Pap testing can be combined with human papillomavirus (HPV) testing, extending the interval to every five years. HPV, the most prevalent sexually transmitted infection (STI), is associated with cervical cancer.

Under certain circumstances, more frequent Pap smears may be recommended by your doctor. These circumstances include a history of cervical cancer, previous detection of precancerous cells, HIV infection, immunosuppression from factors such as organ transplantation, chemotherapy, or prolonged corticosteroid use, and exposure to diethylstilbestrol (DES) before birth. Consult your doctor for personalized advice and guidance.

It’s important for transgender men and nonbinary individuals to prioritize regular Pap smears. Finding a healthcare provider with whom you feel comfortable is essential.

Preparation for Pap Smear:

Avoid scheduling a Pap smear during menstruation as heavy bleeding can affect test accuracy. If your appointment coincides with your period, consult your doctor about rescheduling. To optimize accuracy, adhere to the following guidelines starting 48 hours before your test:

– Refrain from sexual intercourse or using lubricants.
– Avoid using sprays or powders near the vaginal area.
– Do not insert anything into the vagina, including tampons, medications, creams, or suppositories.
– Avoid rinsing the vagina with water, vinegar, or any other fluid (such as douching).

Procedure for Pap Smear:

The entire examination typically lasts 10-20 minutes, with the Pap smear itself taking only a few minutes. Conducted in your doctor’s office or clinic, the procedure involves:

– Assuming a reclined position on the examination table with feet placed in stirrups.
– Spreading the legs while the doctor inserts a speculum (metal or plastic tool) into the vagina to widen its walls, enabling cervix visibility.
– Collecting a sample of cervical cells using a swab, which is then placed in a liquid-filled container for laboratory analysis.
– Although generally painless, you may experience a slight pinch or pressure sensation.

Pap Smear Test Results

Your physician will receive your results within a few days, which will indicate whether they are negative (normal) or positive (abnormal).

Normal Results

A negative result signifies that no precancerous or cancerous cells were detected on your cervix, indicating a healthy outcome. Another Pap smear won’t be necessary until your next scheduled appointment.

Abnormal Results

A positive result doesn’t automatically imply cancer; there are various reasons for an abnormal Pap smear:

– Mild inflammation or minor cell changes (dysplasia)
– HPV or other infections
– Cancer or precancer
– Lab test errors

Typically, abnormal results are associated with cell changes due to the human papillomavirus (HPV), the most common sexually transmitted infection (STI) linked to cervical cancer. These changes in cervical cells caused by HPV can range from mild to severe.

Inflammation may occur if you’ve recently engaged in sexual activity or used a diaphragm before the Pap smear.

In cases of inflammation or minor cell changes, your physician may adopt a “wait and see” approach, possibly recommending another Pap test in a few months.

Further Testing

Your physician will evaluate your results to determine whether additional tests are needed, based on the type of abnormal cells detected in your cervix. Common types include:

1. Atypical squamous cells of undetermined significance (ASCUS): Further testing may involve a liquid-based test to check for HPV presence.

2. Squamous intraepithelial lesion: Depending on the grade of abnormalities, further tests such as colposcopy and biopsy may be required to assess precancerous changes.

3. Atypical glandular cells: Additional tests, including colposcopy, may be necessary to confirm abnormalities in mucus-producing cells.

4. Squamous cell cancer or adenocarcinoma cells: Immediate confirmation through colposcopy and biopsy may be recommended if cancerous cells are suspected.

During a colposcopy, your physician will examine your cervix using a colposcope, identifying any suspicious areas highlighted with a liquid solution. Biopsies of these areas may be taken for further analysis.

Pap Smear Risks

Although generally safe, Pap smears can occasionally miss abnormal cells or cervical cancers, resulting in a false negative. Discuss with your doctor the advantages and risks associated with cervical cancer screening.
