What molar pregnancy is

A molar pregnancy occurs when the fertilisation of the egg by the sperm goes wrong and leads to the growth of abnormal cells or clusters of water filled sacs inside the womb. Molar pregnancy is a type of gestational trophoblastic tumour (GTT for short).


Outlook for molar pregnancy

Doctors collect statistical information about the different types of conditions or diseases and prognosis. Prognosis is the likely outcome of your disease and treatment. In other words, your chances of getting better.

The statistics show that virtually all women who have a molar pregnancy will be cured. Doctors remove all the abnormal molar tissue with surgery and most women need no further treatment. In a small number of women some abnormal cells remain and may spread into the deeper layers of the womb or other parts of the body. This is called persistent trophoblastic disease. Chemotherapy can then usually completely get rid of all the abnormal cells.

There is detailed information about the statistics and outlook for persistent trophoblastic disease in this section.

The chance of having a second molar pregnancy is very low.
