What is colposcopy, and what diseases is it used to diagnose?

In the field of gynecology and obstetrics, early diagnosis is one of the most critical factors directly affecting the success of treatment for many diseases. Especially conditions originating from the cervix can progress without noticeable symptoms in early stages, making regular screening and advanced diagnostic methods extremely important. At this point, colposcopy stands out as a reliable and widely used diagnostic method that enables detailed evaluation of abnormal cellular changes [1].

Colposcopy provides more detailed information than a standard gynecological examination and plays a crucial role in evaluating suspicious results, particularly after a Pap smear test. With this procedure, the cervix, vagina, and vulva are examined under magnification, and if necessary, targeted biopsies can be performed. This allows precancerous lesions to be detected at an early stage.

The Pap smear gives a warning, colposcopy provides the answer. Proper evaluation after an abnormal screening result makes it possible to detect cancer at its earliest and most treatable stage.

What Is Colposcopy and Which Conditions Does It Diagnose?

Colposcopy is a diagnostic procedure that allows detailed examination of the cervix, vagina, and vulva using a special magnification device called a colposcope. The colposcope is a lighted optical system that enables visualization of changes not visible to the naked eye.

This procedure is generally performed in women who have abnormal results from a Pap smear or HPV test. According to the ACOG/ASCCP 2019 risk-based management guidelines, patients who test positive for HPV 16 or HPV 18 are recommended to undergo direct colposcopy regardless of cytology results [2]. During the procedure, special solutions such as acetic acid and iodine are applied to the cervix to make abnormal cells more visible. If necessary, biopsies are taken from suspicious areas to establish a definitive diagnosis.

What Is the Purpose of Colposcopy?

The primary goal of colposcopy is to detect cervical cancer and precancerous lesions at an early stage. While the Pap smear is a screening test that only indicates possible cellular abnormalities, colposcopy allows direct visualization and evaluation of these changes.

Additionally, colposcopy is not limited to the cervix. It is also used to evaluate abnormal lesions in the vaginal and vulvar regions, enabling detailed examination of a broader anatomical area.

When Is Colposcopy Performed?

Colposcopy is typically recommended after abnormal screening test results. Abnormal findings in Pap smear or HPV tests are among the most common reasons for performing colposcopy [1]. Situations that may require colposcopy include:

• Detection of abnormal cells in Pap smear
• Presence of high-risk HPV types (especially HPV 16 and 18)
• Visible lesions on the cervix
• Unexplained vaginal bleeding
• Persistent vaginal discharge

How Is Colposcopy Performed?

Colposcopy is usually performed in an outpatient setting and typically does not require anesthesia. The patient is placed in a gynecological examination position, and a speculum is inserted into the vagina. The colposcope is positioned outside the vaginal opening to visualize the cervix.

Acetic acid and iodine solutions are applied to the cervix, causing abnormal cells to change color and become more visible. The physician carefully examines the cervix under magnification. If suspicious areas are identified, a biopsy may be taken. The procedure is generally completed within 5–15 minutes.

Is Colposcopy Painful?

Colposcopy is generally painless and feels similar to a routine gynecological examination. If a biopsy is taken, a mild stinging or cramping sensation may be experienced. After biopsy, slight bleeding or spotting may occur, which usually resolves on its own.

Conditions Diagnosed with Colposcopy

Common conditions that can be diagnosed with colposcopy include:

• Cervical intraepithelial neoplasia (CIN) – precancerous lesions
• Cervical cancer
• HPV-related cellular changes
• Vaginal and vulvar lesions
• Chronic cervicitis

Relationship Between Colposcopy and HPV

HPV infection is one of the leading causes of cervical cancer. High-risk HPV types can cause cellular changes in the cervix over time that may develop into cancer. In women with positive HPV test results, colposcopy is used to evaluate the cellular effects of the virus. This allows not only detection of the virus but also direct observation of its impact on tissues [2].

Difference Between Colposcopy and Pap Smear

The Pap smear is a screening method that provides information about suspected cellular abnormalities. Colposcopy, on the other hand, is a diagnostic method that allows direct visual assessment. These two methods complement each other; when an abnormality is detected in a Pap smear, a detailed evaluation is performed with colposcopy [1].

Post-Colposcopy Process

After colposcopy, patients can usually return to their daily activities immediately. If a biopsy was performed, mild bleeding or discharge may occur for a few days. Following the doctor’s recommendations is important to prevent infection. Temporary sexual abstinence may be advised after biopsy. The final diagnosis is determined by pathology results, and follow-up, treatment, or further procedures are planned accordingly.

Frequently Asked Questions (FAQ)

• ❓
  Is colposcopy a routine screening method?

  No. Colposcopy is performed when certain risk factors or abnormal test results are present. Routine screening is done with Pap smear and HPV tests.

• ❓
  Does every abnormal colposcopy result mean cancer?

  No. Most abnormal findings are precancerous changes and can be managed with simple treatments. The definitive diagnosis is made through biopsy.

• ❓
  How often should colposcopy be performed?

  Colposcopy is not a screening tool. The frequency is determined by the physician based on Pap/HPV history and individual risk profile.

• ❓
  When will I receive the results?

  If a biopsy is taken, results are usually available within 1–2 weeks.

• ❓
  Can colposcopy be performed during pregnancy?

  Yes. It can be safely performed during pregnancy when necessary.
