Protecting Women’s Health with Early Detection

The new guidelines for Cervical Screening Tests (CSTs) in Australia were introduced in 2017 to improve early detection and prevention of cervical cancer. Thanks to these guidelines, and an excellent recall system, Australia now has the lowest rate of cervical cancer in the world.

Cervical screening is simple, effective, and saves lives.

Understanding Cervical Screening

Simple steps that detect changes early and protect your long-term health.

1. Cervical Screening Test (CST)

Cervical Screening Tests (CSTs) play a vital role in protecting women’s health. Introduced in 2017 to replace the traditional Pap smear, the CST is more accurate and effective in detecting potential risks early.

This test focuses on identifying the presence of the Human Papilloma Virus (HPV), which is the main cause of cervical cancer. With a strong recall system in place, women across Australia can feel reassured that they will be reminded when their next test is due, helping ensure timely care and peace of mind. Key points about the Cervical Screening Test:

Replaced the Pap smear in 2017, offering a more advanced and reliable screening method.
Detects early cell changes that may develop into cervical cancer if left untreated.
The primary focus is on testing for the Human Papilloma Virus (HPV), the main risk factor for cervical cancer.
If HPV is detected, cytology (cell testing) is automatically performed for further investigation.
Women are placed on an excellent recall system, ensuring timely follow-up when their next test is due.

2. Colposcopy

A colposcopy is a simple procedure that allows for a closer examination of the cervix when further investigation is needed. It is usually recommended after certain Cervical Screening Test (CST) results, and helps to identify whether abnormal cells are present.

The test is quick, low risk, and an important step in protecting long-term cervical health. Indications for a colposcopy include:

Persistent HPV infection.
Detection of HPV types 16 or 18, which carry a higher risk of cervical cancer.
Cytology (cell testing) showing a high-grade or possible high-grade lesion.

What to expect during the procedure:

The procedure is quick, usually taking about 4 minutes.
The cervix is examined under a microscope (colposcope) using special stains such as acetic acid and Lugol’s iodine to highlight abnormal areas.
If abnormalities are seen, a small biopsy may be taken for further testing.

3. Treating High Grade Changes (CIN II or III)

Cervical intraepithelial neoplasia (CIN) grades II and III are considered high-grade changes, which can lead to cervical cancer if left untreated. The good news is that these changes can be managed with a straightforward procedure, helping prevent cancer and protect your future health.

Treatment is performed as a simple Day Stay procedure called:

Large Loop Excision of the Transformation Zone (LLETZ).
Also known as LEEP (Loop Electrosurgical Excision Procedure).

Key details about the procedure:

Removes abnormal cervical cells to a depth of around 7mm.
Additional coagulation diathermy is used to ensure treatment of the surrounding margins.
The procedure is quick, usually taking about 15 minutes.
It is highly effective at preventing progression to cervical cancer.

4. Follow-Up After LLETZ

After treatment with a LLETZ (or LEEP) procedure, careful follow-up is essential to ensure the cervix heals properly and that abnormal cells do not return. Regular monitoring provides reassurance and helps maintain long-term cervical health.

Stay on top of your cervical health.

Cervical screening is a safe and highly effective way to prevent cervical cancer. Regular testing, timely treatment, and supportive follow-up care give you the best possible protection.
