A review of 3 earlier studies found that using speculoscopybright light technologyimmediately following a Pap smear may help physicians discover more cervical cancer lesions than the Pap test alone. A negative, however, is that the combination approach may also up the risk of false positives. Analyses of the studies found that using speculoscopy together with Pap smear detected an additional 42 to 62 lesions per 1000 patients screened. The evidence also showed an increase in the number of false positives from 55 to 111 per 1000 patients screened. The reviewers noted, that, because the review found only 3 studies that compared Pap smear alone with Pap smear and speculoscopy, the current data regarding the technology is not strong.
