Poor Policy
Because of poor access to screening and treatment services, the vast majority of
deaths occur in women living in low- and middle-income countries.

Cells are collected from the surface of your cervix by a doctor/nurse
These cells are then checked under a microscope for any abnormalities
If abnormal (or precancerous) cells are found, they can be treated before they turn into cancer
Cervical cancer can be found in the early stages, when it is easier to treat

HPV DNA Testing

HPV DNA TESTING
A sample of cells is collected from the cervix or vagina using a small brush or swab and sent to laboratory for processing
DETECTION OF DNA FROM HIGH-RISK HPV TYPES
![Page 35: Cervical Cancer: Prevention and Control, a Caribbean ... · Bray F, Ren JS, Masuyer E, Ferlay J. Estimates of global cancer prevalence for 27 sites in the adult population in 2008](https://reader034.vdocuments.us/reader034/viewer/2022050513/5f9d870e9d195c7b6e216917/html5/thumbnails/35.jpg)
HPV DNA Testing
3
Samples can be collected by a trained provider or, in the case of vaginal sampling, by the woman herself.
It is not as subjective
More “upstream” in the carcinogenic process, thus enabling for longer safety margin for screening.
Higher sensitivity than Pap smear More effective among women aged 30 years or
older
Advantages
![Page 36: Cervical Cancer: Prevention and Control, a Caribbean ... · Bray F, Ren JS, Masuyer E, Ferlay J. Estimates of global cancer prevalence for 27 sites in the adult population in 2008](https://reader034.vdocuments.us/reader034/viewer/2022050513/5f9d870e9d195c7b6e216917/html5/thumbnails/36.jpg)
HPV DNA Testing
3
Expensive - requiring laboratory facilities,
special equipment, and trained personnel
Takes six to eight hours for results and
Requires follow-up visits for results and
treatment.
