The aim of this work was to demonstrate the effectiveness of colposcopic diagnosis and conservative local treatments in cases of dysplasia after colpo-cytology and directed biopsy. The main treatments applied were cryosurgery and cauterization. The association of dysplasiaand human papillomavirus (HPV) showed an increase of 96% in recent years. The local destructive treatments (TLC), in addition to destroy the virus, have also successfully activated the local immunological system mechanism against HPV. The evidence of such affirmation is based on the obtained results that are: 76% cured, 11% improved, 6.8% persistent, 3.4% recurrence, and only one percent progression.
