lesions (SIL). In healthy women, the low-grade form of this type of abnormality often disappears on its own without treatment. Also, women who are HIV-positive are at an increased risk of infection with human papillomavirus (HPV), which are known to ...

...alignant cervical cells called high-grade cervical intraepithelial
neoplasia (CIN2/CIN3); however HPV testing is less specific than cytology (ie. it produces more 'false-positive' results). HPV testing as a primary screening approach is only feasible if appropriate management is given to women who are HPV-positive w...
