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.
Risk factors for persistent genital HPV infections, which increase the risk of developing cancer, include early age of first sexual intercourse, multiple partners, smoking, and immunosuppression. [1] Genital HPV is spread by sustained direct skin-to-skin contact, with vaginal, anal, and oral sex being the most common methods.
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). [3]
According to Dr. Harrison, “Women should stop having cervical cancer screening after age 65 if they do not have a history of abnormal cervical cells or cervical cancer, and they have had either ...
Screening is recommended for women between ages 21 and 65, regardless of age at sexual initiation or other high-risk behaviors. [17] [18] [19] For healthy women aged 21–29 who have never had an abnormal Pap smear, cervical cancer screening with cervical cytology (Pap smear) should occur every 3 years, regardless of HPV vaccination status.

The Bethesda system (TBS), officially called The Bethesda System for Reporting Cervical Cytology, is a system for reporting cervical or vaginal cytologic diagnoses, [1] used for reporting Pap smear results. It was introduced in 1988 [2] and revised in 1991, [3] 2001, [1] [4] [5] and 2014. [6]
[1] [2] [3] The Papanicolaou stain is one of the most widely used stains in cytology, [1] where it is used to aid pathologists in making a diagnosis. Although most notable for its use in the detection of cervical cancer in the Pap test or Pap smear, it is also used to stain non- gynecological specimen preparations from a variety of bodily ...
A pelvic examination is the physical examination of the external and internal female pelvic organs. [1] It is frequently used in gynecology for the evaluation of symptoms affecting the female reproductive and urinary tract, such as pain, bleeding, discharge, urinary incontinence, or trauma (e.g. sexual assault).
