Alternative Names
Hydatid mole; Molar pregnancyCauses
A hydatidiform mole results from over-production of the tissue that is supposed to develop into the placenta. The placenta normally feeds a fetus during pregnancy. In this condition, the tissues develop into an abnormal growth, called a mass. Often, there is no fetus at all.
The cause is not completely understood. Potential causes may include defects in the egg, problems within the uterus, or nutritional deficiencies. Women under 20 or over 40 years of age have a higher risk. Other risk factors may include diets low in protein, folic acid, and carotene.
