Is a molar pregnancy a tumour?

Dr Sarah Jarvis MBE

A hydatidiform mole is a growing mass of tissue inside your womb (uterus) that will not develop into a baby. It is the result of abnormal conception. It may cause bleeding in early pregnancy and is usually picked up in an early pregnancy ultrasound scan.
