Major advances in screening have lowered the death rate from cervical cancer in the United States. One of the first major advances in cervical cancer screening was the Papanicolaou (Pap) test. The second major advance was liquid-based cytology (LBC). This review presents a wide range of data, discusses the strengths and weaknesses of the available information regarding Pap technologies, and reviews the meta-analyses, which have examined the differences in clinical performance. The review concludes with information on new and future developments to further decrease cervical cancer deaths.
