What should you know about malignant molar pregnancy?

A molar pregnancy develops from abnormal pregnancy-related cells. In some cases, these cells remain or grow after the pregnancy has ended; this is called gestational trophoblastic neoplasia and can behave as cancer. Bleeding between periods, bleeding after a pregnancy or an enlarged uterus can occur, but symptoms alone do not establish the diagnosis.

Doctors follow human chorionic gonadotropin, often called hCG, with blood or urine tests. The pattern over time, examination and imaging help determine whether treatment is needed and whether it is working.

Attend every hCG appointment and tell the team about bleeding, pain, breathlessness, headaches or visual changes. Chemotherapy is commonly used when persistent or malignant trophoblastic disease needs medicine; the regimen depends on the diagnosis and risk assessment.

Use reliable contraception if advised, because a new pregnancy can make hCG results difficult to interpret. Ask about treatment side effects, emotional support and when it may be appropriate to plan a future pregnancy.

Get emergency help for heavy vaginal bleeding, fainting, severe abdominal pain, sudden breathlessness, chest pain, a severe headache, confusion or a seizure. Contact the specialist team promptly for fever during chemotherapy, persistent vomiting, unusual bruising or bleeding that is increasing.

What type of gestational trophoblastic disease do I have? What do my hCG results show? Which chemotherapy plan is recommended, and how will side effects be treated? How often will monitoring continue? What contraception and fertility advice applies to me?
