ovarian cancer with its 17.9% takes third place, as well as it is the leading cause for death (8.4%) among the women with gynecological
cancer. The present study shows, that the increased risk for
ovarian cancer is connected with the advanced age, the use of some hormonal medicaments, diet reach of animal
fats, as well as the presence of family history or
hereditary cancer syndromes (5-10% of the cases). From the other site, decrease of the risk is present when there are more deliveries, breastfeeding, low calories vegetable diet,
oral contraceptives use, sterilization and prophylactic
oophorectomy. It is pointed out, that prophylactic
oophorectomy is the only effective method for the prevention of the
