[Does cancer preventive care on the cervix need to be reformed? Gynecological preventive care and early diagnosis--current knowledge on cervix neoplasms].

A comparative study shows high incidence of preclinical cancerous lesions of the uterine cervix in women under thirty years of age. The rate of positive cytology in this age group was the same as in the group of women over thirty (0.3 per cent each). The histological findings revealed intraepithelial lesions like dysplasia and carcinoma in situ in the younger group compared to more advanced lesions like microinvasive cancer in the higher-aged group. The use of colposcopy rendered optical evidence--predominantly in the younger group--of lesions which under long-term observation preceded positive cytology for years as well as the consequent histological proof of dysplasia and preclinical carcinoma. As a result of the given and discussed clinical data in both compared age groups the value of colposcopy is stressed in improving the quality of detection of preclinical neoplasia in the uterine cervix and the necessity of cancer-screening in younger-aged women is emphasized.
