Pap smear and HPV: what to know

Pap smear and HPV test: the differences, when to have them and why they are essential for prevention

The Pap smear and the HPV test are two simple, quick exams that are essential for the prevention of cervical cancer. Although they are often mentioned together, they have different but complementary roles: one analyses the cells of the cervix, while the other looks for the presence of the human Papillomavirus (HPV).

Knowing the difference between these two exams helps you approach screening with greater awareness and peace of mind, understanding why regular check-ups matter even in the absence of symptoms.

What is the Pap smear?

The Pap smear is a cytological exam that detects any changes in the cells of the cervix before they can develop into more serious problems.

During the exam, the gynecologist or midwife takes a small sample of cells from the cervix using a special brush or spatula. The sample is then analysed in a laboratory.

The Pap smear makes it possible to:

• detect abnormal or precancerous cells;
• act early when necessary;
• monitor the health of the cervix over time.

What is the HPV test?

The HPV test is a molecular exam that looks for the presence of the human Papillomavirus (HPV), a very common virus transmitted mainly through sexual intercourse.

Most HPV infections are cleared spontaneously by the immune system. However, some types of HPV, known as high-risk types, can persist over time and cause changes in the cells of the cervix.

The HPV test makes it possible to:

• identify the presence of high-risk HPV;
• assess the risk of developing cervical changes;
• establish whether closer follow-up is needed.

Why is cervical screening important?

Cervical cancer is one of the cancers where prevention can make a real difference. Screening tests can detect changes at an early stage, when they can be monitored and treated much more easily.

The Pap smear and the HPV test are therefore not just diagnostic tools: above all, they prevent disease through regular check-ups.

What is the difference between the Pap smear and the HPV test?

The Pap smear and the HPV test are performed with a very similar sampling procedure, but they do not look for the same thing.

They are two complementary exams: the HPV test looks for the virus, while the Pap smear checks whether the virus has already caused changes in the cells of the cervix.

Is the exam painful?

No. For most women the Pap smear and the HPV test cause only mild discomfort or a feeling of pressure lasting a few seconds.

The sampling is quick, requires no anaesthesia and is performed during a normal gynecological visit.

How to prepare for the Pap smear or HPV test?

Proper preparation ensures an adequate sample and therefore a more reliable result.

Before the exam it is advisable to:

• avoid having the test during your period; the ideal time is a few days after your period ends;
• avoid sexual intercourse in the 24–48 hours before the exam;
• avoid pessaries, vaginal creams, douches or other vaginal products in the days before, unless your doctor advises otherwise;
• inform your gynecologist if you are pregnant, have unusual vaginal discharge or an ongoing infection.

When should the Pap smear or HPV test be performed?

For women with no symptoms and average risk, Italian screening programmes schedule regular check-ups based on age.

• Between the ages of 25 and 29: a Pap smear every 3 years.
• Between the ages of 30 and 64: an HPV test every 5 years if the result is negative.

If the HPV test is positive, further investigations are scheduled, which may include a Pap smear and, when necessary, a colposcopy.

If I have symptoms, should I wait for my screening appointment?

No. Screening is designed for women who have no symptoms.

You should book a gynecological visit if you notice:

• bleeding after sexual intercourse;
• bleeding between periods;
• bleeding after menopause;
• unusual or persistent vaginal discharge;
• persistent pelvic pain.

Even with a previous normal Pap smear or HPV test, these signs always deserve a specialist assessment.

If I am vaccinated against HPV, do I still need check-ups?

Yes. HPV vaccination is a very important prevention tool, but it does not protect against all types of Papillomavirus.

This is why it is essential to keep taking part in screening programmes for your age group, even after vaccination.

Frequently asked questions

Are the Pap smear and the HPV test the same thing?

No. They are two different exams: the Pap smear analyses the cells of the cervix, while the HPV test looks for the presence of the HPV virus.

If the HPV test is positive, does it mean I have cancer?

No. A positive result only indicates the presence of the HPV virus. In most cases the infection is cleared spontaneously by the immune system.

Only a small proportion of persistent infections can cause cell changes that require specific follow-up.

If I am vaccinated against HPV, do I still need screening?

Yes. The vaccine significantly reduces the risk, but it does not replace the check-ups scheduled by prevention programmes.

Are the Pap smear and the HPV test done together?

In some cases yes, but it depends on the woman's age, the screening guidelines and her individual clinical situation.

When the HPV test is positive, a Pap smear may also be performed on the same sample to check whether the virus has already caused cell changes.

Based on the results, the gynecologist may suggest further investigations, such as a colposcopy.

Prevention is the most important gesture for women's health

The Pap smear and the HPV test are simple, quick exams that are essential for the early detection of any changes of the cervix.

Taking part regularly in screening programmes means taking care of your health with a gesture of prevention that can make all the difference.

If you are unsure which check-up is right for your age, or would like to schedule a gynecological visit, talking to a specialist is the first step to receiving personalised information and approaching prevention with peace of mind.
