[Contraception and risk factors for the development of diseases of the uterine cervix].

In a group of 350 women operated on account of diseases of the uterine cervix in 1986-1988 risk factors associated with cancerogenesis were evaluated. The author provided evidence of a significant rise of CIN in conjunction with contraception. The rise of number of CIN cannot be differentiated from social factors and sexual behaviour of women which are directly related to the increased risk of cancer of the uterine cervix.
