Cervical cancer was the most frequent HPV-associated cancer with on average 292 cases per year (74% of the female total, and 54% of the overall total of HPV-associated cancers). [197] A study of 996 cervical cytology samples in an Irish urban female, opportunistically screened population, found an overall HPV prevalence of 19.8%, HPV 16 at 20% ...
The highest-risk types are HPV 16 and 18; these are responsible for the vast majority of HPV-related cancers, including cancers of the cervix, vagina, vulva, penis, anus, and head and neck.
Virtually all cervical cancer cases (99%) are linked to genital human papillomavirus infection (HPV); [14] [5] [6] most who have had HPV infections, however, do not develop cervical cancer. [3] [15] HPV 16 and 18 strains are responsible for approximately 70% of cervical cancer cases globally and nearly 50% of high grade cervical pre-cancers.
HPV+OPC presents in one of four ways: as an asymptomatic abnormality in the mouth found by the patient or a health professional such as a dentist; with local symptoms such as pain or infection at the site of the tumor; with difficulties of speech, swallowing, and/or breathing; or as a swelling in the neck (if the cancer has spread to lymph nodes).
HPV, the human papillomavirus, causes six types of cancer, including cervical cancer. Among women aged 20 to 24, cervical cancer incidence dropped by 65% from 2012 to 2019, according to a report ...

It has been observed that HPV18 is the most prevalent type in Small cell cervical cancer. Like other types of cervical cancer it seems to be associated with high-risk (e.g. 16, 18, 31) HPV Infection. [1]
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.
