According to the current estimates and identify genetic family history of cancer nest egg <BR> syndrome, is not absolutely reliable. Many women with hereditary ovarian cancer syndrome family history characteristics, but not detected gene mutation, on the contrary, the detection of gene mutations in certain women, family history is not typical. Furthermore gene mutation detection methods in molecular biology is still not perfect, a negative result does not completely ruled out the existence of tumor-related gene mutations.
Census ovarian cancer several methods, including ultrasound, serum CA125 determination, but not very successful.
The present study has clearly oral contraceptives on the general population has decreased risk of ovarian cancer protection. Its protective mechanism to be related to inhibition of ovulation ovarian effects. With medication and time extension, with the risk of ovarian cancer drop by more noticeable.
