High magnification together with green filter is often used to identify certain vascular patterns that may indicate the presence of more advanced pre-cancerous or cancerous lesions. [citation needed] The squamocolumnar junction, or "transformation zone", is a critical area on the cervix where many precancerous and cancerous lesions most often ...
The cervix (pl.: cervices) or cervix uteri is a dynamic fibromuscular sexual organ of the female reproductive system that connects the vagina with the uterine cavity. [1] The human female cervix has been documented anatomically since at least the time of Hippocrates, over 2,000 years ago.
The cause of CIN is chronic infection of the cervix with HPV, especially infection with high-risk HPV types 16 or 18. It is thought that the high-risk HPV infections have the ability to inactivate tumor suppressor genes such as the p53 gene and the RB gene, thus allowing the infected cells to grow unchecked and accumulate successive mutations, eventually leading to cancer.
[3] [25] It is the second-most common cause of female-specific cancer after breast cancer, accounting for around 8% of both total cancer cases and total cancer deaths in women. [ 26 ] 88% (2020 figure) of cervical cancers and 90% of deaths occur in low- and middle-income countries (LMICs) and 2% (2020 figure) in high-income countries (HICs) .

The Papanicolaou test (abbreviated as Pap test, also known as Pap smear (AE), [1] cervical smear (BE), cervical screening (BE), [2] or smear test (BE)) is a method of cervical screening used to detect potentially precancerous and cancerous processes in the cervix (opening of the uterus or womb) or, more rarely, anus (in both men and women).

Cervical conization refers to an excision of a cone-shaped portion of tissue from the mucous membrane of the cervix. Conization is used for diagnostic purposes as part of a biopsy and for therapeutic purposes to remove pre-cancerous cells ( cervical intraepithelial neoplasia ) or early stage cervical cancer .
