Definition

Gestational trophoblastic disease (GTD) refers to a group of abnormalities in which tumors grow inside a woman's uterus (womb). The abnormal cells start in the tissue that would normally become the placenta, the organ that develops during pregnancy to feed the fetus.

A baby may or may not develop during these types of pregnancies.

There are several types of GTD. They include:

* Choriocarcinoma (a type of cancer)
* Hydatiform mole (also called a molar pregnancy)
