Classification of Pap smear results (Bethesda, 2001):

  • the absence of dysplasia or cancer cells (NILM) - negative;
  • presence of atypical glandular cells: inflammatory changes (AGUS-NOS), suspected invasive growth (AGC, favor neoplastic), malignant neoplasm of the cervix (AIS);
  • presence of atypical squamous cells: inflammatory lesions (ASC-US), mild dysplasia (LSIL, CIN1), moderate (CIN2), severe (HSIL, CIN3), malignancy (CIS).

The presence of single atypical cellsevidence of inflammatory changes. A large number of atypical cells - a sign of precancerous lesions (high-grade dysplasia). The presence of cells with signs of malignancy - the initial stage of cervical cancer (AIS, CIS). The analysis results are not the final diagnosis!
