What is the rate of incidence of gestational trophoblastic tumors?

In the United States, hydatidiform moles develop in approximately 1 in every 1000 to 1500 pregnancies. Chorioadenoma destruens (invasive moles) occur in approximately 1 in 15,000 pregnancies. Choriocarcinomas are even less common, occurring in approximately 1 in 20,000 to 40,000 pregnancies. Placental site trophoblastic tumors are less frequent than choriocarcinomas; they are very rare.

In the United States, gestational trophoblastic tumors make up less than one percent of all cancers affecting the female reproductive organs. Gestational trophoblastic tumors are more common in many Asian and African countries.
