Answer
A PAP smear is a test for cervical cancer. By looking at the cells of your cervix, we can see if there is any changes in the cells that lead to cancer. The spectrum is as follows: Normal, ASCUS (atypical squamous cells of undetermined origin), LSIL(low grade squamous intrepithelial lesion), HSIL (high grade squamous intrapethelial lesion), CIS (carcinoma-in-situ), Cancer.  ASCUS is the lowest abnormality. It just means that the view under the microscope was "atypical" and it was of undetermined significance. That means it could have been normal. We usually repeat the PAP smear in 3-6 months and if it reverts back to a normal PAP, we ignore the previous PAP. Don't worry.
