Cervical Cancer Screening: Why Every Woman Should Get Screened

Cervical cancer is one of the most preventable forms of cancer, yet it remains one of the leading causes of cancer-related deaths among women in many low- and middle-income countries, including Nigeria. The good news is that regular cervical cancer screening can detect abnormal cells long before they become cancerous, allowing treatment before cancer develops.

Every woman should understand the importance of cervical cancer screening because early detection saves lives.

What is Cervical Cancer?

Cervical cancer develops in the cells of the cervix—the lower part of the uterus that connects to the vagina.

Most cervical cancers are caused by persistent infection with certain high-risk types of the Human Papillomavirus (HPV), a common sexually transmitted virus.

Although HPV infection is very common, not everyone infected develops cervical cancer. Regular screening identifies abnormal changes before they progress.

What is Cervical Cancer Screening?

Cervical cancer screening is a preventive medical test used to detect:

• Precancerous cervical changes
• Abnormal cervical cells
• Early-stage cervical cancer
• High-risk HPV infection

The purpose is not just to find cancer, but to detect changes before cancer develops.

Types of Cervical Cancer Screening

1. Pap Smear (Pap Test)

A Pap smear examines cervical cells under a microscope.

It helps detect:

• Abnormal cells
• Precancerous changes
• Early cervical cancer

Procedure

A healthcare provider:

• Inserts a speculum into the vagina.
• Collects cells from the cervix using a small brush or spatula.
• Sends the sample to a laboratory.

The procedure usually takes less than five minutes.

2. HPV Test

The HPV test detects high-risk HPV strains responsible for nearly all cervical cancers.

It can:

• Detect infection before abnormal cells appear.
• Assess future cancer risk.
• Be performed together with a Pap smear (co-testing).

3. Co-testing

Some women may undergo both:

• Pap smear
• HPV test

This provides the highest sensitivity for detecting cervical abnormalities.

Why is Cervical Cancer Screening Important?

Regular screening:

• Detects precancerous cells early.
• Prevents cervical cancer.
• Reduces cancer deaths.
• Allows less invasive treatment.
• Improves survival rates.
• Identifies HPV infection before cancer develops.

Women who undergo regular screening are significantly less likely to develop advanced cervical cancer.

Who Should Get Screened?

General recommendations include:

Ages 21–29

• Pap smear every 3 years (if results are normal).

Ages 30–65

One of the following:

• HPV test every 5 years.
• Pap smear every 3 years.
• Pap smear + HPV test every 5 years.

Over 65 Years

Women with a history of consistently normal screening results may be able to stop screening after discussing with their healthcare provider.

Women with certain medical conditions may require more frequent screening.

Who is at Higher Risk?

Risk factors include:

• HPV infection
• Multiple sexual partners
• Early sexual activity
• Smoking
• HIV infection
• Weak immune system
• Long-term oral contraceptive use
• Previous abnormal Pap smear
• Family history of cervical cancer
• Not receiving regular screening

Symptoms of Cervical Cancer

Early cervical cancer often causes no symptoms, making routine screening essential.

As the disease progresses, symptoms may include:

• Abnormal vaginal bleeding
• Bleeding after sexual intercourse
• Bleeding after menopause
• Persistent pelvic pain
• Pain during intercourse
• Foul-smelling vaginal discharge
• Unexplained weight loss
• Fatigue

Seek medical evaluation promptly if you experience these symptoms.

How to Prepare for a Pap Smear

Before your appointment:

• Avoid sexual intercourse for 24–48 hours.
• Avoid vaginal creams or medications unless advised.
• Avoid douching.
• Do not schedule the test during heavy menstrual bleeding.
• Inform your healthcare provider if you are pregnant.

Does Cervical Cancer Screening Hurt?

Most women experience only mild discomfort or pressure during the test.

The procedure:

• Is quick.
• Does not require anesthesia.
• Usually lasts only a few minutes.
• Allows normal activities afterward.

Understanding Your Results

Normal Result

No abnormal cervical cells were detected.

Continue routine screening as recommended.

Abnormal Result

An abnormal result does not necessarily mean cancer.

It may indicate:

• HPV infection
• Mild cervical changes
• Moderate or severe precancerous changes
• Inflammation
• Infection

Your healthcare provider may recommend:

• Repeat testing
• HPV testing
• Colposcopy (a closer examination of the cervix)
• Biopsy if needed

Can Cervical Cancer Be Prevented?

Yes. Most cervical cancer cases are preventable.

Effective prevention includes:

HPV Vaccination

Vaccination protects against the HPV types responsible for most cervical cancers.

It is most effective before exposure to HPV.

Regular Screening

Routine screening detects abnormalities before cancer develops.

Safe Sexual Practices

• Use condoms consistently.
• Limit the number of sexual partners.
• Seek prompt treatment for sexually transmitted infections.

Stop Smoking

Smoking weakens the immune system and increases the risk of cervical cancer.

Healthy Lifestyle

Support your immune system by:

• Eating fruits and vegetables.
• Exercising regularly.
• Sleeping adequately.
• Managing stress.
• Maintaining a healthy weight.

Cervical Cancer and HPV

Nearly all cervical cancers are linked to persistent infection with high-risk HPV.

However:

• Most HPV infections resolve naturally.
• Persistent infection can lead to precancerous changes over several years.
• Regular screening identifies these changes early.

Cervical Cancer Screening in Nigeria

Many women in Nigeria are diagnosed at advanced stages due to:

• Lack of awareness.
• Fear of screening.
• Limited access to screening services.
• Financial barriers.
• Cultural misconceptions.

Increasing awareness and access to screening can significantly reduce cervical cancer deaths.

Common Myths About Cervical Cancer Screening

Myth 1: I have no symptoms, so I don't need screening.

Fact: Early cervical cancer often has no symptoms.

Myth 2: The test is painful.

Fact: Most women experience only mild discomfort.

Myth 3: Only older women get cervical cancer.

Fact: Women of various ages can develop cervical cancer, which is why age-appropriate screening is important.

Myth 4: HPV infection means I have cancer.

Fact: Most HPV infections do not lead to cancer.

Frequently Asked Questions (FAQs)

How long does a Pap smear take?

Usually less than 5 minutes.

Can unmarried women get screened?

Yes. Screening recommendations are based primarily on age and individual risk factors, not marital status.

Can I get screened during pregnancy?

In many cases, yes. Your healthcare provider will determine the appropriate timing.

How often should I be screened?

Follow your healthcare provider's recommendation based on your age, medical history, and previous screening results.

Does screening prevent cancer?

Screening itself does not prevent cancer, but it detects precancerous changes that can be treated before they develop into cancer.

Conclusion

Cervical cancer is one of the few cancers that can often be prevented through vaccination, regular screening, and early treatment of precancerous changes. By staying informed, attending routine screening appointments, and discussing any concerns with a qualified healthcare provider, women can greatly reduce their risk of developing advanced cervical cancer.

If you are due for screening or have symptoms such as abnormal vaginal bleeding or persistent pelvic pain, schedule an appointment with a healthcare professional promptly.
