Changes to This Summary (04/10/2014)
Revised text to state that the benefits of screening women younger than 21 years are small because of low prevalences of lesions that will progress to invasive cancer; screening is not beneficial in women older than 65 years if they have had a history of recent negative tests (cited Moyer et al. as reference 3).
Added text to state that testing for low-risk human papillomavirus types does not identify women at risk for cervical intraepithelial neoplasia 2 or 3 (cited Thomsen et al. as reference 45 and Castle et al. as reference 46).
Added text to state that women aged 20 years and younger have a very low risk of cervical cancer and a high likelihood that cervical cell abnormalities will go away on their own (cited Saslow et al. as reference 68).
