[N2 laser in diagnosis of early cervical cancer].

Two-hundred and thirty-three cases of severe cervical erosion with positive or doubtful Pap smear or atypical cervical proliferation were examined by N2 laser stimulating intrinsic fluorescence method in order to detect early cervical cancer and precancerous lesions. This diagnosis can be made by the fluorescence color or by drawing a curve in a dark room. The correspondent rate to pathological findings was 100% for cervical cancer and 93.9% for cervical dysplasia.
