Trigger factors of ovarian cancer

In addition to genetic factors there were four other factors that influence the risk of ovarian cancer that reproductive factors, hormonal factors, and environmental factors. To take precautions, then we need to know the trigger factors that can increase the risk of ovarian cancer.



The biggest impact on this disease caused by the reproductive history (pregnancy, childbirth) and the duration and distance of reproduction, low parity (number of low birth) and infertility (sterility), menars (first got menstrual) early and late menopause increase the risk for developing ovarian cancer.



Multiple pregnancies (twins) can enhance the protective effect against the development of ovarian cancer.



When compared with women who never gave birth, one to two pregnancies result in the relative risk (RR) from 0.49 to 0.97. Women with pregnancies of more than three had a reduced risk of 0.35 to 0.76 when compared with the control population.



The use of exogenous hormones in the treatment of menopausal symptoms were also associated with an increased risk of incidence or mortality from ovarian cancer.



Some literature suggests that the use of long-term hormone replacement therapy (> 5-10 years) lead to increased risk by 1.5-2.0-fold.



Specifically the increased risk seen in women users of estrogen without progesterone. Increased body weight also allows an increase in the risk of contracting this disease.



Some studies show a link increased body mass index (BMI) during adolescence or adulthood with an increased risk, especially in the premenopausal period.



Another related factor is the environmental factor. On average the highest incidence of ovarian cancer occur in Caucasian women in industrialized countries as in North America and Europe. This may be related to differences in reproductive patterns and environmental components, such as differences in diet.



In one study, referred to women with ovarian cancer diet can be found in the Western dietary pattern, ie high meat and few vegetables. This is possibly related to high rates of ovarian cancer incidence.



Vegetables and fruits, said to have a positive effect, while high consumption of meat may increase a woman's risk of developing ovarian cancer. Some studies also suggested that tobacco consumption increases the incidence of ovarian cancer in women.
