In the prevention of cervical carcinoma, the determination of factors of probable etiopathogenetic factors is essential. Although of fundamental importance is the infection with Human Papilloma Virus, significant other factors are habitual tobacco use, hypo immunity. There is an association with decreased serum Vitamin A levels, poor nutritional status and higher incidence of CIN. Higher incidence is also associated with lower economic standards, polygamous sex life and multiparity. A certain importance is also ascribed to some individual factors, specific and nonspecific infectious factors within the vagina and cervix, as well as to long-term exposure to some chemical agents. Barrier contraceptives offer some protection to infectious agents.
