The family history of ovarian cancer
Ovarian cancer usually happens in a family aggregate.
Women who have relatives stricken with ovarian cancer have a higher risk of
developing ovarian cancer than women of the same. Therefore, family history is
one of the important factors of ovarian cancer.
2.
Age
Ovarian cancer can occur at any age and the incidence
increases with age. It is commonly seen among women in menopause and rarely
occurs in children of women under 20. Moreover, various types of ovarian
cancers have different age distributions. For example, the incidence of
epithelial ovarian cancer quickly climb after age 40 with a peak at age 50-60
and gradually decreased after 70, while ovarian germ cell tumors often seen
among the girls before the age of 20 and is targeting women who are single or
never has spawned.

Early menarche and late menopause
Animal experiments showed that the ovarian epithelium
proliferates rapidly after ovulation and ovulation active mitosis about the
position. As reported, a growing number of ovulatory cycles during the life of
women ', higher risk of ovarian cancer they have. Therefore, early menarche and
late menopause are some of the important risk factors of ovarian cancer.

Being not married or never given birth
Research has found that women who are not married or
never given birth have a 1.7 times higher risk of developing ovarian cancer
compared with those who had given birth. Pregnancy can reduce the risk of
ovarian cancer. The more often and the number of months of pregnancy, lower
risk of ovarian cancer women have. First pregnancy play a role protecting the
strongest, which can reduce the risk of ovarian cancer 40%.

Contacts with powdered talc and asbestos
Experiments showed that talc powder and asbestos can
transfer the abdominal cavity, causing epithelial ovarian atypical hyperplasia
and thereby increase the risk of ovarian cancer. Study abroad found that
asbestos workers have an increased risk of ovarian cancer is higher than
ordinary women.
6.
Diets high in fat
Diets containing high animal fat can increase the risk of
ovarian cancer by the following mechanisms:
a. Animal fats cause cancerization through some hormonal
effects. For example, under the influence of gut bacteria, animal fats are
absorbed can produce estrogen, which can stimulate ovarian cancer.
b. Polycyclic hydrocarbons animal fats have the effect of
ovarian cancerization animals.
c. Animal fats are absorbed can change the immunity of
the organism, increasing the risk of cancerization.
