The Pap smear is a screening tool used for cervical cancer. Pap smear results can be normal, unclear and abnormal. When the results are either unclear or abnormal, further testing is necessary.

The changes in cell can be either minor, moderate or more advanced, states WebMD. Although having an abnormal Pap result may not mean cancer, other tests are used to further evaluate the cause or extent of changes in cervical cells. These additional tests may be a colposcopy or HPV test. A colposcopy is a procedure to examine more closely the cervix. A biopsy may be taken during this exam. If the cell changes are in a more advanced stage, then treatment is necessary to excise these cells.
