Invasive mole and choriocarcinoma
No one can tell you exactly how long you will live
Below are general statistics based on large groups of people. Remember, they can’t tell you what will happen in your individual case.
Chemotherapy works very well for most women with invasive mole or choriocarcinoma. Those who need chemotherapy are divided into 3 different risk groups - low risk, high risk and ultra high risk disease.
There are no UK wide statistics for invasive mole and choriocarcinoma.
Results are available from research undertaken at the specialist UK centres that treat these conditions. In this research, women were followed up for between 1 and 16 years after their diagnosis. The number of people included is quite low, particularly for the ultra high risk group.
All women (100%) with low risk disease are successfully treated.
All those (100%) with high risk disease are successfully treated.
Around three quarters (75%) of those with ultra high risk disease are successfully treated.

An invasive mole and choriocarcinoma are rare cancers. They grow from the tissue that forms in the womb during pregnancy.
If you develop an invasive mole or choriocarcinoma it usually shows up on some tests before you notice any symptoms. Your specialist team will then ask you to go in to see them.
The stage of an invasive mole or choriocarcinoma tells you how far it has spread. Your doctors will look at this and other risk factors to plan your treatment.
The main treatment for invasive mole or choriocarcinoma is chemotherapy. But some women might be offered surgery.
Invasive mole and choriocarcinoma are very rare types of cancer that can occur after pregnancy. They are types of gestational trophoblastic disease (GTD).
Gestational trophoblastic disease (GTD) is a group of rare tumours that start in the cells that would normally develop into the placenta during pregnancy. Abnormal cells grow inside the womb but they are different to womb cancer.
