You seem to be slightly confused! Pap. tests don't have anything to do with a rectal colonoscopy. Pap. tests are to detect vaginal, cervical or uterine problems. Colonoscopy is to identify rectal/bowel problems. Two different tests for two different areas. Dysplasia can be easily treated with a D&C (dilation & curettage). Cervical erosion can be treated by laser.
