Now a new study finds these women are at higher risk for a type of growth known as "borderline ovarian tumors." They are typically not aggressive, and experts say even if the tumor does spread, the vast majority of women survive these tumors.
Even so, researchers say treating borderline ovarian tumors can require extensive surgery.
The International Federation of Fertility Societies has issued a statement saying it believes the risks are low but is calling for continued vigilance in watching out for this possibility.
