Gestational trophoblastic disease
Gestational trophoblastic disease (GTD) is a group of conditions 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.
- Choriocarcinoma (a type of cancer)
- Hydatiform mole (also called a molar pregnancy)
