Human papillomavirus (HPV) is a group of 150 related viruses. In most cases, HPV leaves on its own but the risk of cancer in organs that carry out reproductive functions increase due to HPV. It is a common virus and all men and women get it at some point in their lives. The transmission of HPV happens through intimate skin-to-skin contact. Also, HPV is transmitted through vaginal, anal, or oral sex.

cervical cancer caused by HPV is the second common form of cancer in women worldwide. Nearly 600 thousand cases of cervical cancer were reported, resulting nearly in 300 thousand deaths. 85% of deaths related to cervical cancer occurs in countries outside North America.

It is important to understand HPV vaccines do not protect against all HPV types. Therefore, routine checks for precancerous changes in cervical cells becomes more than necessary. Cervical cancer screening includes HPV DNA test and Pap test.
