Worldwide, an estimated 660,000 new cases of cervical cancer were diagnosed in 2022, with approximately 350,000 deaths.

Opens in new window Cervical cancer is the fourth most common cancer diagnosed in women and ranks second in resource-limited countries.
Cervical cancer is caused primarily by persistent infection of the cervix with human papillomavirus (HPV). HPV is a sexually transmitted infection and is common in sexually active individuals. Most infections resolve spontaneously, but persistent infection of the cervix, if untreated, can cause abnormal, precancerous cells to develop. Cervical screening can detect precancerous and cancerous lesions in asymptomatic women.[1]American College of Obstetricians and Gynecologists. Updated cervical cancer screening guidelines. Apr 2021 [internet publication].

Cervical cancer screening has been hailed as one of the most successful preventive medical strategies. It has been associated with a 70% reduction in cervical cancer mortality in developed countries since the introduction of the Papanicolaou (Pap) test in 1941.[6]Wright TC Jr. Cervical cancer screening in the 21st century: is it time to retire the PAP smear?

HPV infection of cervical epithelial cells is associated with characteristic morphologic changes, and the presence of HPV can, therefore, be indicated by histopathologic observation. HPV tests, either alone or with cytology, are a newer method of cervical cancer screening.
Cervical cancer is rare in women under the ages 21 years. Routine screening is recommended for those with a cervix ages 21 years to 65 years. Screening may be clinically indicated in women over the ages 65 years who have not had adequate prior screening or are at high risk of cervical cancer. Women who have undergone total hysterectomy (i.e., their cervix has been removed) no longer need cervical cancer screening, as long as they have no previous history of cervical cancer or dysplasia. Women of any age who have a limited life expectancy can also discontinue cervical cancer screening.[1]American College of Obstetricians and Gynecologists.
