What is Gestational trophoblastic tumours (GTT) and molar pregnancy?
Gestational trophoblastic tumours (GTT)
Depending on the exact variation of the disease, GTT can be known by a number of names, including: trophoblastic disease, persistent trophoblastic disease, gestational trophoblastic neoplasia and gestational trophoblastic disease.
What is GTT?
As the name would suggest, Gestational Trophoblastic Tumours are related to pregnancy. GTT grows in the womb, and can either be either benign (non-cancerous) or malignant (cancerous). Though it starts in the womb, GTT is very different than womb cancer, in that it grows from the tissue that forms in your womb when you are pregnant, and acts in a very different way.
Gestation means pregnancy, and trophoblastic refers to the cells that grow in the womb during the normal course of a baby’s development. In the case of GTT, some of these cells grow abnormally, and form tumours.
In molar pregnancy, one form of GTT, the fetus doesn’t develop normally, or at all, and the cells can morph into non-cancerous tumours. All gestational trophoblastic tumours begin in the womb, but can spread outside.
The different types of GTT?
There are a number of different conditions that fall under the general umbrella of GTT, including molar pregnancy, invasive moles, placental site trophoblastic tumour (PSTT), choriocarcinoma and persistent trophoblastic disease.
The most common type of GTT is molar pregnancy, which is not cancerous.
Nearly all forms of GTT, both cancerous and non-cancerous, are curable.
