Colposcopy: what it is, when it is needed and how this important screening exam is performed

Colposcopy

Hearing the word colposcopy can be a little worrying, especially the first time it is prescribed. In reality it is a simple, safe and generally well-tolerated exam, essential for investigating any changes of the cervix found during a Pap smear or HPV test.

Colposcopy is one of the most important tools in the prevention of cervical cancer, because it allows the doctor to observe with great precision any areas that require further investigation and, if necessary, to act promptly.

What is a colposcopy?

Colposcopy is a gynecological exam that provides a magnified view of the cervix, vagina and vulva through an instrument called a colposcope.

The colposcope does not enter the body: it remains outside and works like a special illuminated magnifying glass, allowing the gynecologist to identify changes that would not be visible during a normal visit.

To highlight the areas to be examined, some specific solutions are gently applied, such as acetic acid and Lugol's solution, which make any cell changes easier to recognise.

When is it recommended?

Colposcopy is not a routine exam: it is prescribed when the result of other tests needs further investigation.

The most frequent situations are:

• A Pap smear showing cell changes.
• A positive HPV test for high-risk strains.
• Bleeding after sexual intercourse.
• Changes of the cervix observed during a gynecological visit.
• Follow-up after treatment for cervical lesions.

Being advised to have a colposcopy does not mean having cancer. In most cases it simply serves to clarify the nature of small changes, which often turn out to be benign or easily treatable.

How is the exam performed?

A colposcopy is carried out very much like a normal gynecological visit.

• The patient settles on the examination couch.
• A speculum is gently inserted to visualise the cervix.
• The gynecologist observes the area with the colposcope, which remains outside the body.
• Specific solutions are applied to highlight any changes.
• If needed, a small targeted biopsy may be taken.

The whole procedure generally takes between 10 and 20 minutes.

Is colposcopy painful?

In most cases colposcopy is not painful. Inserting the speculum may cause slight discomfort, similar to a normal gynecological visit.

If a biopsy is needed during the exam, you may feel a brief pinch or a light cramp lasting a few seconds.

Once the exam is over you can immediately return to your normal daily activities.

How to prepare for a colposcopy?

To obtain more accurate images it is advisable to follow a few simple recommendations.

• Avoid scheduling the exam during your period.
• Do not use vaginal douches or creams in the two days before.
• Avoid sexual intercourse in the 24–48 hours before the exam.
• Bring the results of your most recent Pap smears, HPV tests or previous visits.

What happens after the exam?

If no biopsy is taken, no particular precautions are needed.

If a small tissue sample is taken, light spotting in the following days is normal. It is generally advisable to avoid sexual intercourse, tampons and swimming pools for a few days, following your gynecologist's advice.

The histological exam, if performed, will establish whether periodic check-ups or further treatment are needed.

Frequently asked questions

Is colposcopy used to diagnose cancer?

No. Colposcopy is a follow-up exam that allows early detection of any changes of the cervix, which are often benign or easily treatable.

Can I drive after the exam?

Yes. Unless your doctor advises otherwise, you can immediately return to your normal activities, including driving.

If my Pap smear is abnormal, does it mean I have cancer?

Absolutely not. Most Pap smear abnormalities are due to cell changes related to HPV infection and only rarely indicate cancer. Colposcopy serves precisely to clarify the situation.

Can a colposcopy be performed during pregnancy?

Yes, when the gynecologist considers it necessary. It is regarded as a safe exam during pregnancy too, and is performed with special care for the health of mother and baby.

Prevention is the best way to take care of your health

Approaching a colposcopy with the right information helps you face the exam with greater peace of mind. It is a precious tool that allows early detection of any changes of the cervix and, when necessary, early treatment.

Taking part regularly in gynecological screening, having Pap smears and HPV tests as recommended and attending the suggested follow-ups is a concrete investment in your health and in prevention.
