In the United States, about 2â3 million abnormal Pap smear results are found each year. Most abnormal results are mildly abnormal (ASC-US (typically 2â5% of Pap results) or low-grade squamous intraepithelial lesion (LSIL) (about 2% of results)), indicating HPV infection.
Plus, abnormal Pap smear results are extremely common. Six to 10 million women will be told at some point in their lives they have an abnormal Pap, Nevadunsky says. Every week, she adds, she sees three or four women with abnormal results. What the Pap smear is actually testing for are any changes in cervical cells that could be precancerous.
