Cervical cancer screening has been one of medicine's best preventive health successes, contributing to a reduction in cervical cancer rates through early detection programs. Understanding Australia's renewed Cervical Screening Program, including HPV testing and screening schedules, is helping more women to make informed decisions about their care and health in Toowoomba.
Understanding Cervical Cancer and Prevention
Cervical cancer develops in the cervix, the lower portion of the uterus connecting to the vagina. Nearly all cervical cancers result from persistent infection with high-risk human papillomavirus (HPV) types, which is why screening and vaccination play a huge role in prevention of cervical cancer.
What role does HPV play in cervical cancer?
Human papillomavirus infections are very common, affecting approximately 80% of sexually active people at some point. Most HPV infections resolve naturally without causing health problems, but persistent infections with high-risk HPV types can lead to cellular changes that may progress to cancer over time.
High-risk HPV types most commonly associated with cervical cancer include HPV 16, 18, 31, 33, 45, 52 and 58. These types cause approximately 99% of cervical cancers worldwide, making HPV detection critical to screening strategies.
How does early detection help prevent cervical cancer?
Cervical screening may help identify precancerous changes before cancer develops, allowing for treatment that prevents cancer occurrence. This is why regular screening remains essential even for vaccinated women.
The progression from HPV infection to cervical cancer typically takes 10-15 years, providing multiple opportunities for detection and intervention through regular screening programs.
Australia's Cervical Screening Program
The Australian Cervical Screening Program changed significantly in 2017, transitioning from two-yearly Pap tests to five-yearly HPV testing for women aged between 25 and 74. This renewed approach supports early detection and reduces screening frequency for most women.
Key program changes
HPV testing is now the primary screening method, offering greater sensitivity for detecting high-risk HPV infections that may require closer monitoring, further assessment or treatment.
Screening intervals extended to five years for women with negative HPV results, reflecting the detection capabilities of HPV testing compared to previous cytology-only approaches.
Screening commencement age increased to 25 years based on evidence that cervical cancer is uncommon in younger women and that screening benefits are limited before this age.
Screening eligibility and recommendations
All women and people with a cervix aged 25-74 are encouraged to participate in regular cervical screening, regardless of sexual activity history, relationship status or HPV vaccination status.
Screening remains important for vaccinated women because current vaccines do not protect against all high-risk HPV types.
Women who have never been sexually active have a very low cervical cancer risk but may choose to discuss screening with their healthcare provider based on individual circumstances.
Cervical screening explained
Cervical screening involves collecting cells from the cervix during a brief procedure that can be performed by doctors, nurse practitioners or specially trained practice nurses in Toowoomba clinics.
What to expect during your cervical screening
The screening procedure typically takes 5-10 minutes and involves inserting a speculum into the vagina to inspect the cervix, then using a small brush to collect cells from the cervical surface.
Preparation recommendations include:
- Scheduling appointments for mid-cycle when possible
- Avoiding sexual intercourse 24 hours before your screening
- Not using vaginal medications or douches before your appointment
- Discussing any concerns or previous abnormal results with your GP
