characterized by a ranging number of immature cells; these cells are precancerous and, if not removed, may progress to invasive cancer

Moderate to severe dysplasia (pre-cancerous cells), also called CIN-2 or CIN-3, which is diagnosed by performing a colposcopy and biopsy. Fewer than 1 percent of Paps are described by the lab as falling into this category. If confirmed by a colposcopy, such cell changes are highly likely to develop into cancer and require immediate treatment.
