Choriocarcinoma is a fast-growing cancer that occurs in a woman's uterus (womb). The abnormal cells start in the tissue that would normally become the placenta. This is the organ that develops during pregnancy to feed the fetus.

Choriocarcinoma is a rare cancer that occurs as an abnormal pregnancy. A baby may or may not develop in this type of pregnancy.
The cancer may also occur after a normal pregnancy. But it most often occurs with a complete hydatidiform mole. This is a growth that forms inside the womb at the beginning of a pregnancy. The abnormal tissue from the mole can continue to grow even after attempted removal, and can become cancerous. About one half of all women with a choriocarcinoma had a hydatidiform mole, or molar pregnancy.

Exams and Tests
A pregnancy test will be positive, even if you are not pregnant. The pregnancy hormone (HCG) level will be high.
A pelvic exam may find an enlarged uterus and ovaries.
Blood tests that may be done include:
Imaging tests that may be done include:
- CT scan
- Pelvic ultrasound
- Chest x-ray
You should be carefully monitored after a hydatidiform mole or at the end of a pregnancy. Early diagnosis of choriocarcinoma can improve the outcome.
After you are diagnosed, a careful history and exam will be done to make sure the cancer has not spread to other organs. Chemotherapy is the main type of treatment.

Most women whose cancer has not spread can be cured and will still be able to have children. A choriocarcinoma may come back within a few months to 3 years after treatment.
The condition is harder to cure if the cancer has spread and one or more of the following happens:
- Disease spreads to the liver or brain
- Pregnancy hormone (HCG) level is higher than 40,000 mIU/mL when treatment begins
- Cancer returns after having chemotherapy
- Symptoms or pregnancy occurred for more than 4 months before treatment began
- Choriocarcinoma occurred after a pregnancy that resulted in the birth of a child
Many women (about 70%) who have a poor outlook at first go into remission (a disease-free state).
