Cervical cancer is one of the cancers that can often be prevented or detected at a precancerous stage through appropriate screening.

Regular cervical cancer screening can identify abnormal changes in the cells of the cervix before they develop into cancer.

What Is Cervical Cancer?

Cervical cancer develops in the cervix, the lower part of the uterus that connects with the vagina.

Persistent infection with certain high-risk types of Human Papillomavirus (HPV) is responsible for the great majority of cervical cancers.

HPV infection is very common and most infections resolve spontaneously. However, persistent infection with a high-risk HPV type can cause abnormal cervical cell changes which, over several years, may progress to cancer.

This long precancerous period is why screening is so effective.

What Is a Pap Smear?

A Pap smear, also called a Pap test, is a screening test used to look for abnormal or precancerous changes in cells collected from the cervix.

During the test, a speculum is gently inserted into the vagina so that the cervix can be seen. A small brush or similar sampling device is then used to collect cervical cells.

The sample is sent to a laboratory for examination.

The procedure usually takes only a few minutes.

Pap Smear vs HPV Test

Although both are used for cervical cancer screening, they look for different things.

Pap Smear

The Pap test looks for abnormal changes in cervical cells that could potentially become cancerous.

HPV Test

An HPV test looks for infection with high-risk HPV types associated with cervical cancer.

Depending on a woman's age, history and applicable screening recommendations, screening may involve:

• HPV testing alone

• Pap cytology alone

• HPV testing together with cytology

Your gynaecologist can advise which screening method and interval are appropriate for you.

Who Should Have Cervical Cancer Screening?

Women should undergo cervical cancer screening according to appropriate age-based recommendations and their individual medical history.

The appropriate test and frequency can vary according to:

• Age

• Previous screening results

• Previous abnormal Pap or HPV tests

• Immune status

• Previous treatment for precancerous cervical lesions

• Other individual risk factors

Women who have had a hysterectomy should also discuss with their doctor whether continued screening is necessary, as this depends on the reason for surgery, whether the cervix was removed and previous cervical abnormalities.

Why Screen If I Have No Symptoms?

Precancerous cervical changes usually do not cause symptoms.

A woman may feel completely healthy while abnormal cervical cells are developing.

Screening is therefore performed before symptoms develop.

Finding and treating significant precancerous changes can prevent many cases from progressing to invasive cervical cancer.

How Is a Pap Smear Performed?

The test is generally straightforward and takes only a few minutes.

Step 1 – Examination

You lie on the examination table while the doctor gently inserts a speculum into the vagina.

Step 2 – Cervical Sample

A small brush or sampling device is used to collect cells from the surface of the cervix.

Step 3 – Laboratory Testing

The collected sample is sent to the laboratory for examination.

Step 4 – Results

Your doctor reviews the report and advises whether routine screening, repeat testing or further evaluation is required.

Is a Pap Smear Painful?

Most women experience little or no pain, although temporary pressure or mild discomfort may occur when the speculum is inserted or the cervical sample is taken.

The procedure itself is usually brief.

If you are particularly anxious or have previously experienced discomfort during pelvic examinations, tell your doctor beforehand.

How Should I Prepare for a Pap Smear?

When booking your screening appointment, inform your doctor if you are menstruating, pregnant, have unusual vaginal discharge or are being treated for a vaginal infection.

For the most suitable sample, your doctor may advise avoiding certain vaginal products, medicines or intercourse for a short period before the test.

If your period starts before your appointment, ask the clinic whether the test should be rescheduled.

What Do Pap Smear Results Mean?

A Pap smear result may be reported as normal or may show different types of cellular abnormalities.

An abnormal Pap smear does NOT automatically mean that you have cervical cancer.

Abnormal results may occur because of HPV-associated changes or other cellular abnormalities.

Depending on the result, your doctor may recommend:

• Repeat testing

• HPV testing

• Colposcopy

• Cervical biopsy

• Further follow-up or treatment

The appropriate next step depends on the specific laboratory result and your previous screening history.

What Is Colposcopy?

A colposcopy is a more detailed examination of the cervix using magnification.

It may be recommended following certain abnormal Pap smear or HPV test results.

During colposcopy, suspicious areas of the cervix can be examined closely and, when necessary, a small biopsy may be taken for laboratory examination.

An abnormal screening test therefore does not establish a diagnosis of cancer—it identifies women who may require further evaluation.

Symptoms That Should Not Be Ignored

Screening is intended mainly for women without symptoms.

Consult a gynaecologist promptly if you experience:

• Bleeding after sexual intercourse

• Bleeding between periods

• Bleeding after menopause

• Persistent unusual or blood-stained vaginal discharge

• Unexplained persistent pelvic pain

• Pain during intercourse

These symptoms can have many non-cancerous causes, but they should be appropriately evaluated.

Women with symptoms should seek medical assessment rather than waiting for their next routine screening test.

HPV Vaccination & Cervical Cancer Prevention

HPV vaccination provides protection against important HPV types responsible for cervical cancer and several other HPV-related diseases.

Vaccination is most effective when given before exposure to HPV, but recommendations vary according to age and individual circumstances.

HPV vaccination does not eliminate the need for cervical cancer screening.

Women who have been vaccinated should continue screening according to appropriate recommendations.

Can Cervical Cancer Be Prevented?

The risk of cervical cancer can be substantially reduced through a combination of:

• HPV vaccination

• Appropriate cervical cancer screening

• Follow-up of abnormal screening results

• Treatment of significant precancerous lesions

• Avoidance of tobacco

• Seeking medical evaluation for suspicious symptoms

The key is not simply having a Pap smear once, but maintaining appropriate screening and follow-up over time.

When Was Your Last Cervical Cancer Screening?

Many women postpone screening because they feel healthy or have no symptoms.

However, cervical screening is most valuable before symptoms appear.

A short appointment today may identify cervical changes years before they could become a serious problem.
