What is it?

Choriocarcinoma is a fast-growing cancer that occurs in a woman's uterus (womb). The abnormal cells start in the tissue that would normally become the placenta. This is the organ that develops during pregnancy to feed the fetus.
Choriocarcinoma is a type of gestational trophoblastic disease. Gestational trophoblastic disease (GTD) is a broad term encompassing both benign and malignant growths arising from products of conception in the uterus.
The cancer often occurs with a complete hydatidiform mole, which is an abnormal tissue formed inside the womb at the beginning of the pregnancy. It can also develop during a normal pregnancy, after delivery, or after an early pregnancy that does not continue (miscarriage).
