Complete Hydatidiform Mole


A complete hydatidiform mole happens when cells turn into abnormal tissue in the uterus. The cells normally form the placenta. The tissue is a cluster of fluid-filled cysts that look like grapes. The cluster continues to grow and fill the uterus. The abnormal tissue is not cancer but may become cancer. A complete hydatidiform mole is also called a complete molar pregnancy. With a complete molar pregnancy, there is no fetus.


Follow up with your healthcare provider in 2 days or as directed:

A complete molar pregnancy can be life-threatening. Even after treatment for a complete molar pregnancy, some abnormal cells can spread to other areas of your body. The tissue can become cancerous. You may also have bleeding after treatment. Keep all follow-up appointments. You will need more tests. You may also need more treatment.


  • Use birth control as directed. Do not get pregnant for at least 12 months. You are at high risk for another complete molar pregnancy.
  • Do not have sex or use tampons until your healthcare provider says it is safe. Sex and tampons increase your risk for bleeding, infection, or damage to the uterus.

Contact your healthcare provider if:

  • You bleed longer or more than your healthcare provider says you should.
  • You have abdominal pain after treatment.
  • You have headaches that are not relieved by medicine.
  • You have questions or concerns about your condition or care.

Seek immediate care or call 911 if:

  • You cough up blood.
  • You have blood in your bowel movements.
  • You have chest pain or trouble breathing.
  • You have changes in your speech and in your vision.
  • You cannot move one side of your body.
