TROPHOBLAST CANCER Meaning and
Definition
-
Trophoblast cancer, also known as gestational trophoblastic disease (GTD), is a rare type of cancer that occurs in the cells that are normally present in the placenta during pregnancy. The trophoblast is a layer of cells that surrounds the embryo and forms the outer layer of the developing placenta, which provides nourishment and support to the growing fetus.
Trophoblast cancer typically arises from abnormal or overactive trophoblast cells, which may result from abnormal fertilization of an egg or abnormal development of the placenta. This type of cancer can manifest as various subtypes, including hydatidiform mole, invasive mole, choriocarcinoma, placental-site trophoblastic tumor, and epithelioid trophoblastic tumor.
Symptoms of trophoblast cancer may include vaginal bleeding or spotting, passage of grape-like cysts or tissue through the vagina, enlarged uterus, hyperemesis gravidarum (severe nausea and vomiting), and high levels of the pregnancy hormone human chorionic gonadotropin (hCG) that persist or increase instead of decreasing as pregnancy progresses.
Treatment for trophoblast cancer is usually highly effective, especially when diagnosed in the earlier stages. It typically involves removal or evacuation of the abnormal tissue and subsequent chemotherapy to eliminate any remaining cancer cells. In cases where the cancer has spread beyond the uterus, additional therapies such as radiation therapy or surgery may be necessary. Regular follow-up examinations and monitoring of hCG levels are essential to ensure that the cancer is successfully treated and does not recur.

Etymology of TROPHOBLAST CANCER
The word "trophoblast" comes from the Greek words "trophē" meaning "nourishment" and "blastos" meaning "germ" or "sprout". In biology, the trophoblast is the outer layer of cells that forms during the early stages of embryo development. It plays a crucial role in the implantation of the embryo into the uterine wall and in the formation of the placenta.
The term "trophoblast cancer" refers to a rare type of cancer called Gestational Trophoblastic Neoplasia (GTN). GTNs are tumors that develop from the trophoblastic cells, which typically grow into the placenta during a normal pregnancy. However, in the case of GTN, these cells become abnormal and can develop into cancerous growths.
