a type of tumour that grows like a pregnancy inside the uterus - called a molar pregnancy

2 types:

• complete mole
• partial mole

Complete mole -

• 2 sperm cells fertilise an ovum that contains no genetic material (empty ovum), these sperm then combine genetic material, cells start to divide into a tumour called a complete mole
• No fetal material will form

Partial mole -

• 2 sperm cells fertilise a normal ovum (containing genetic material) at the same time
• the new cell has 3 sets of chromosomes (haploid cell), cell divides and multiples into tumour called a partial mole
• Some fetal material may form

Molar pregnancy behaves like a normal pregnancy. Periods will stop and the hormonal changes of pregnancy will occur. There are a few things that can indicate a molar pregnancy versus a normal pregnancy:

• More severe morning sickness
• Vaginal bleeding
• Increased enlargement of the uterus
