Cervical squamous intraepithelial lesion (SIL), previously called cervical intraepithelial neoplasia (CIN), is a form of dysplasia that can progress to cervical cancer. The term carcinoma in situ may be used interchangeably with high-grade SIL. [8] Ductal carcinoma in situ of the breast is the most common precancer in women.
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.
For premalignant dysplastic changes, the CIN (cervical intraepithelial neoplasia) grading system is used. [7] Colon cancer: originally consisted of four stages: A, B, C, and D (the Dukes staging system). More recently, colon cancer staging is indicated either by the original A-D stages or by TNM. [8] Kidney cancer: uses TNM. [9]
Cervical intraepithelial neoplasia (CIN) means the development of abnormal cells on the surface of the cervix. It is caused by an HPV infection but in most cases, it is resolved by the immune system. However, a small percentage of people might develop a more serious CIN which, if left untreated, can develop into cervical cancer.
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).

In liquid-based cytology, a sample of cells is taken using a small brush. The cells are put into a container of liquid, and analysed for abnormalities. Cervical cells to be tested for HPV are collected in a similar way. [5]
