Miscarriage is the loss of a pregnancy before the 20th week of pregnancy. Most miscarriages are caused by abnormal embryonic development.

Molar pregnancy is usually benign, but in some cases it can lead to scary complications such as invasive molar pregnancy or trophoblastic cancer.

Molar pregnancy occurs when a zygote forms and develops into an abnormal mass in the uterus. Molar pregnancy is an abnormal pregnancy condition. If not detected and treated early, it can lead to many dangerous complications such as: blood loss, hemorrhage, trophoblastic cancer... Molar pregnancy ultrasound is an effective paraclinical diagnostic method that allows early identification of molar pregnancy.

Gestational trophoblastic disease is a term used to describe diseases associated with abnormal proliferation of trophoblasts during pregnancy. Gestational trophoblastic disease is divided into two types: trophoblastic tumor and hydatidiform mole.
