Invasive mole. The myometrium is the muscular wall of the uterus. It can be invaded by an abnormal placenta from a hydatidiform mole. When that happens, it's called an invasive mole. Sometimes, this can be seen on ultrasound or MRI.
Hydatidiform mole, invasive mole, cancers of pregnancy, or molar pregnancy
This occurs when cancer affects the tissues that would otherwise form in pregnancy. This is not a viable pregnancy, but an abnormal one, because a fetus does not develop.
It is usually benign (not cancer) but it may spread to nearby tissues (invasive mole). It may also become a malignant tumor called choriocarcinoma. Hydatidiform mole is the most common type of gestational trophoblastic tumor.
Because of the risk of invasive moles and choriocarcinoma, the hCG level is monitored after molar pregnancy. Initially, monitoring is weekly. The hCG level generally drops to normal within 8 to 12 weeks following evacuation of the mole (Moore).
Invasive mole - the tumour spreads into the wall of the uterus.
Metastatic mole - cancer cells migrate to other organs of the body and cause secondary tumours. The lungs are common sites for metastatic moles.

T cells identify invasive molecules, such as viral proteins, and help B cells to produce antibodies that are designed specifically to attack these invaders.
Invasive mole (chorioadenoma destruens) occurs in 1: 12,000 pregnancies. This is a progressive form of hydatidiform mole that has invaded the myometrium or other structures. Choriocarcinoma is an epithelial tumor that occurs in 1:40,000 pregnancies.
A low-risk invasive mole or metastatic disease often can be treated successfully with methotrexate (multiple brand names) either alone or in combination with leucovorin (Wellcovorin).

In some cases, hydatidiform moles may develop into invasive moles. These moles may grow so far into the uterine wall and cause bleeding or other complications.
Cancer is found only in the space inside the uterus. If the cancer is found in the muscle of the uterus, it is called an invasive mole (choriocarcinoma destruens).

hCG monitoring will identify the small number of women who develop a persistent or invasive mole. There is a 10% chance of this happening, and if it does happen it is classed as malignant (cancerous).
