The article gives critical analysis of numerous epidemiological studies touching upon the problems of carcinogenesis while using hormonal contraception and hormonal replacement therapy and also the expediency of HRT as to oncologic patients after radical treatment.
The materials presented testify to relative carcinogenous safety of hormonal contraceptives as to the majority of tumors and even considerable decrease of endometrial and ovarian cancer risk; but some investigations point to the increase о f breast cancer in case о f prolonged application о f hormonal preparations.
The results оf the analysis show that HR Tmay be recommended among female population providing active screening, especially of mammary glands and endometrium.
