Atlas of visual inspection of the cervix with acetic acid for screening, triage, and assessment for treatment

VIA procedure Ė Examination after application of 5% acetic acid Ė Abnormal features Ė Rapidity of onset of acetowhitening

  

In metaplasia, inflammation, or low-grade precancer, the acetowhite area appears slowly over 20Ė30 seconds and fades away quickly. While applying acetic acid to the cervix, VIA providers should look for the real-time changes on the transformation zone.





In contrast, in high-grade precancer or cancer, the acetowhite changes take place very rapidly and persist for a longer period of time.




Invasive cervical cancers turn acetowhite almost immediately.
