Gestational Trophoblastic Disease (GTD) is a rare group of conditions in which abnormal cells grow inside the uterus after conception. These cancers form from the cells that would normally develop into the placenta, which connects the fetus to the uterus. Although it begins during pregnancy, GTD is not a typical pregnancy and cannot result in a viable birth.
The good news: when detected early and treated appropriately, GTD is often highly curable.
Symptoms can mimic those of a normal or early miscarriage. They may include:
Yes, it is possible to get pregnant after a molar pregnancy. The risk that a future pregnancy will also be a molar pregnancy is approximately 1%. If you’ve had two molar pregnancies, the risk of a third increases to 15–20%.
It is generally recommended to wait 6 months after treatment of a molar pregnancy before attempting pregnancy, and 1 year after treatment of other types of gestational trophoblastic disease. This is because hCG levels—a hormone produced during pregnancy—are also used to monitor for recurrence of the disease. Since hCG naturally rises during pregnancy, trying to conceive too soon can make it difficult to tell whether the hormone is increasing due to a healthy pregnancy or a possible recurrence.
