What are the chances of having a second molar pregnancy?

About 1 in 1,000 pregnancies (less than 1 percent) in the United States is a molar pregnancy. Most women who have a molar pregnancy can go on to have a healthy pregnancy later. The risk of having another molar pregnancy is only about 1 to 2 in 100 women (1 to 2 percent).

Is molar pregnancy recurrence?

Overall recurrence risk for molar pregnancy was 1.8% (1 in 55), or a 20-fold increase compared with the background risk. Of 27 cases with repeat complete moles, three had further complete moles, suggesting the recurrence risk following two previous complete moles is approximately 10%.

Are molar pregnancies genetic?

Molar pregnancies are caused by an imbalance in genetic material (chromosomes) in the pregnancy. This usually occurs when an egg that contains no genetic information is fertilised by a sperm (a complete molar pregnancy), or when a normal egg is fertilised by two sperm (a partial molar pregnancy).

What causes a molar pregnancy?

A molar pregnancy occurs when an egg and sperm join incorrectly at fertilization and a noncancerous tumor forms instead of a healthy placenta. The tumor, or mole, cannot support a developing embryo, and the pregnancy ends. It is also called a hydatidiform mole.

What are the complications of molar pregnancy?

If a molar pregnancy is not treated or does not miscarry completely it can progress and cause a range of serious conditions (known as gestational trophoblastic neoplasia), including: persistent GTD – persistent growth of the abnormal placental tissue. invasive mole – the tumour spreads into the wall of the uterus.

Is a molar pregnancy a miscarriage?

A molar pregnancy will not be able to survive. It may end on its own, with a miscarriage. If this does not happen, it’s usually treated with a procedure to remove the pregnancy.

Is there a risk of a recurrence of molar pregnancy?

The risk of recurrence is low, but higher than the risk for women with no previous history of molar pregnancy. During any subsequent pregnancies, your care provider may do early ultrasounds to monitor your condition and offer reassurance of normal development.

How often do molar pregnancies occur in the US?

Also, although most molar pregnancies occur after a miscarriage, some occur after an ectopic (tubal) pregnancy or even a normal delivery. The incidence of molar pregnancy varies depending on where one lives. For example, in the US about 1 out of every 1000 pregnancies is a molar pregnancy. In Southeast Asia the incidence is 8 times higher.

Can a woman still be pregnant after removing a molar?

This occurs in approximately 15 to 20 percent of complete molar pregnancies, and up to 5 percent of partial molar pregnancies. One sign of persistent GTN is a high level of human chorionic gonadotropin (HCG) — a pregnancy hormone — after the molar pregnancy has been removed.

What is the medical term for a molar pregnancy?

Molar pregnancies are an uncommon and very frightening complication of pregnancy. The formal medical term for a molar pregnancy is “hydatidiform mole.” Simply put, a molar pregnancy is an abnormality of the placenta (afterbirth), caused by a problem when the egg and sperm join together at fertilization.
