Cytologic tests include conventional Pap smear and liquid based cytology. Visual Inspection tests involve application of a solution to enhance identification of abnormal areas and can utilize the naked eye or a colposcope/magnifying camera. [3] Medical organizations of different countries have unique guidelines and screening recommendations.
Cervical cancer begins when the cells that line the cervix become abnormal and grow in a pattern that is atypical for non-cancerous cells. [14] Cervical cancer is typically first identified with an abnormal pap smear. [14] The final diagnosis of cervical cancer, including the stage of the cancer, is confirmed with additional testing.

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).

Pap stain. High-grade squamous intraepithelial lesion (HSIL or HGSIL) indicates moderate or severe cervical intraepithelial neoplasia or carcinoma in situ. It is usually diagnosed following a Pap test. In some cases these lesions can lead to invasive cervical cancer, if not followed appropriately. [citation needed]
HPV testing can identify most of the high-risk HPV types responsible for CIN. HPV screening happens either as a co-test with the Pap smear or can be done after a Pap smear showing abnormal cells, called reflex testing. Frequency of screening changes based on guidelines from the Society of Lower Genital Tract Disorders (ASCCP).
Endocervical curettage is a medical procedure used to extract cells of the endocervix to visualize under a microscope. Direct cervical visualization, colposcopy, and even endocervical colposcopy are not enough to fully analyze all areas of the endocervical epithelium and thus endocervical curettage is the method of choice in cases where this is necessary.
Examples of epithelial dysplasia include cervical intraepithelial neoplasia – a disorder commonly detected by an abnormal pap smear) consisting of an increased population of immature (basal-like) cells which are restricted to the mucosal surface, and have not invaded through the basement membrane to the deeper soft tissues.
Pap test screening can reveal abnormal cells on the surface of the cervix called cervical intraepithelial neoplasia (CIN) that in a small percentage can develop into cervical cancer. These precancerous changes can be confirmed with further examination known as colposcopy .
