HPV testing for cervical cancer: the good, the bad, and the ugly

A randomized, controlled trial has shown human papillomavirus (HPV) DNA testing with and without liquid-based cytology to be more sensitive but less specific than conventional Papanicolaou smears for detection of precancerous lesions of the cervix. The lead-time advantage of early detection of precancerous lesions by HPV DNA testing resulted in cervical cancer reduction; however, an increased detection of possibly regressive precancerous lesions could result in unnecessary treatment, especially in women aged 25–34 years.
