Persistent trophoblastic disease (PTD) is a tumour that can form in the womb after an abnormal type of pregnancy called a molar pregnancy.
Choriocarcinoma is a very rare tumour that can occur after a normal pregnancy, a molar pregnancy, a miscarriage or a termination of pregnancy (abortion).
These tumours are types of gestational trophoblastic disease (GTD).
When you might have surgery
Surgery is not often used for PTD and chroriocarcinoma. Usually, you only have chemotherapy.
Your doctor might suggest surgery if your PTD or choriocarcinoma doesn't respond to the chemotherapy (it is chemoresistant). In this case they might suggest that you have your womb removed (a hysterectomy) or surgery to remove disease that has spread to other parts of the body.
In this situation your doctor or specialist nurse will provide you with more information about the operation and what it will involve.
