When can I become pregnant after a gestational trophoblastic tumor?

After you are treated for gestational trophoblastic tumor, your doctor will want to make sure that the tumor is fully gone before you become pregnant. This is because the main way to determine if the tumor is gone is to follow your blood levels of human chorionic gonadotrophin (HCG). Beta-HCG levels are usually elevated with GTT, but should return to normal with effective removal. Because HCG levels also rise if you are pregnant, becoming pregnant will interfere with the usefulness of HCG as an indicator of remaining disease. This may prevent you from getting appropriate treatment. Pregnancy should therefore be avoided until your doctor approves, which is usually six months to two years after the last treatment.

Right after conception, certain women are at risk for developing grape-shaped tumors in her uterus called gestational trophoblastic tumors (jeh-STAY-shuh-nul troh-fuh-BLAS-tik TOO-mer).Also known as gestational trophoblastic disea...

se, this condition develops from the abnormal accumulation of cells that are responsible for helping a fertilized egg attach itself to a womans uterus, where a baby grows. The tumors can turn cancerous and spread outside the uterus; when this happens, it is called choriocarcinoma. On the other hand, the tumor can be classified as a hydatidiform mole, which causes cysts and does not spread outside the uterus. These moles are more common than choriocarinomas. Women are at greater risk for developing these tumors if they have had a miscarriage or an abortion, are of a childbearing age or have had previous moles in their uterus. Visit your doctor if you have vaginal bleeding that is not related to your period.
