“A molar pregnancy (also called a hydatidiform mole or HM) is a tumor (growth) that develops in the uterus (womb) at the beginning of pregnancy. In a molar pregnancy, the placenta doesn’t form correctly. Instead it develops into a mass of cysts (small sacs filled with fluid) and can’t supply the baby with food and oxygen like it does in a healthy pregnancy.
A molar pregnancy almost always ends in pregnancy loss. 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).
If not treated, a molar pregnancy can be dangerous to the woman. It sometimes can cause a rare form of cancer.
A molar pregnancy is a kind of gestational trophoblastic disease (also called GTD). This is a group of conditions that cause tumors to grow in the uterus.” Read More
