Cervical cancer screening and updated Pap guidelines.

Cervical cancer and its dysplasia precursors account for significant morbidity and mortality in women worldwide. Human papillomavirus infection is common, preventable, and now widely accepted as the causative agent with oncogenic potential in the development of cervical cancer. Screening via Papanicolaou testing is critical, and interpretation of test results with knowledge of patient risk factors is imperative. Many evidence-based guidelines for screening, interpretation, and management have been developed and are widely available for use.
