As many as one in four hundred women test positive for the BRCA-1 gene, often called the "breast cancer gene."

They have not only a significantly increased risk for breast cancer, but also for ovarian cancer.

Now a new study suggests if women with this gene want to lower their risk for ovarian cancer drastically, they need to have their ovaries removed by age 35.

"Removing the ovaries and fallopian tubes really does have a positive impact on that woman, and reduces her risk of ovarian cancer tremendously and also improves her survival," explains Dr. Ursula Matulonis of the Dana Farber Cancer Institute.

The study found those who had their ovaries removed had an 80-percent lower chance for developing ovarian cancer, and an equally low rate of premature death.

It also means the inability to conceive a child and immediate menopause.
