Visible DNA ploidy abnormal cells are a finding when performing liquid-based cytology and have clinical significance including cancer, inflammatory irritation, and cervical erosion. It indicates that there is some degree of cytopathy in the cervix, but screening for cervical cancer is needed to rule out cancer. This is because normal cells should be DNA 1-ploidy and cells that are dividing are 2-ploidy. However, cells with more than 2 DNA are ploidy abnormal cells, most commonly tumor cells. Cancer cells are not the only cells that have abnormal ploidy DNA, but also cells that have fused due to inflammatory infections, so a cervical biopsy is needed to determine if cancer is present. If cancer is ruled out, it means that it is caused by inflammatory infection. Further examination of cervical lesions by cervical biopsy to rule out cervical cancer determines the pathological changes of cervical cells.
