Introduction Different approaches to screening and treatment of cervical precancer Anatomical considerations

Anatomical considerations Gross anatomy of female genital organs, External genitalia Internal genital organs Gross anatomy of the cervix Cervical epithelium Squamous epithelium Columnar epithelium Squamocolumnar junction (SCJ)

Physiological changes of the cervical epithelium

Ectropion Squamous metaplasia Transformation zone of the cervix Changes induced by pregnancy Atrophic changes Congenital transformation zone (CTZ)

Neoplastic changes of the cervical epithelium

Genesis of cervical cancer – Role of HPV HPV structure and types Genesis of precancerous lesions and cervical cancer Cervical intraepithelial neoplasia (CIN) Adenocarcinoma in situ (AIS) Cervical cancers

HPV tests – Variation between tests Instruments, consumables, and setup required

for collection of samples for HPV testing (provider-collected) for self-collection of samples for HPV testing

Procedure to collect samples for HPV testing

Sample collected by a health provider Counselling of a woman undergoing HPV testing History taking Preparation for sample collection for HPV testing Steps for inspection of the external genitalia Steps for insertion of the speculum and exposure of the cervix Steps for collection of cervical samples Steps for self-collection of samples Storage of the samples after collection, and transportation to the laboratory

The possible side-effects and complications of the thermal ablation procedure are the same as those for cryotherapy. The duration of vaginal discharge is usually shorter with thermal ablation.

Post-treatment advice and follow-up
The post-treatment advice and follow-up for thermal ablation are the same as those for cryotherapy.
