Gestational Trophoblastic Disease (GTD) is a group of rare tumors that develop from the cells that form the placenta during pregnancy. It includes conditions like molar pregnancy, where abnormal tissue grows instead of a normal embryo. GTD can lead to complications if not diagnosed and treated promptly. The main types of GTD are complete moles and partial moles, which differ in their genetic makeup and potential for cancerous growth. Most cases are treatable, and monitoring human chorionic gonadotropin (hCG) levels helps track recovery. Early detection is crucial for effective management and positive outcomes.
