Is hydatidiform mole hereditary?

No. A hydratidiform mole occurs in a molar pregnancy. This is an abnormal form of pregnancy where a egg that had lost its dna becomes fertilized by sperm (complete mole) or an egg becomes fertilized by two sperm or a sperm that has duplicated itself (partial mole). Molar pregnancies occur randomly, in about 1/1000 pregnancies, and cannot survive. They can develop into choriocarcinoma, a form of cancer.
Molar pregnancy. In general it is not. There are case reports of familial events (ie, seven molar pregnancies in 6 sisters).

What is the difference between a complete and a partial hydatidiform mole?

Genetics + more. A complete mole is formed when a sperm fertilizes an empty egg & duplicates, or when two sperm fertilize an empty egg. It has 46 chromosomes(all paternal). A partial mole develops when two sperm(or one sperm that duplicates) fertilize an egg & has 69 chromosomes. Fetal parts are usually only found in partial moles. Complete moles inc risk for choriocarcinoma(a type of tumor) more than partial moles. Read more...
Molar pregnancy. A partial mole develops at either at conception (2 sperm fertilize 1 egg) or immediately after conception (1 sperm enters an egg and duplicates). A complete mole forms similarly but with an empty egg. A partial mole has about a 5% and a complete mole 15% chance of becoming a gestational trophoblastic neoplasia. Read more...

Why do women under 20 or over 40 years of age have a higher risk of a hydatidiform mole?

Molar pregnancy. Being younger or older is a risk factor for a molar pregnancy. One of the causes of a molar pregnancy is dispermy, or the fertilization of the egg by two sperm. Perhaps the eggs of younger or older women are more susceptible to this happening. This is my opinion. Read more...

What further treatments are required after the removal of a hydatidiform mole?

Following HCG levels. After a woman has a D&C to remove a molar pregnancy, it is usually recommended that she go on a reliable method of birth control and avoid conceiving for a year. Serial measurements of the HCG level are done and are important to determine if the molar prenancy has been completely removed and then to make sure that there is not reocurrance, which is associated with a poorer outcome.

Had hydatidiform mole pregnancy, it was terminated bec cystic hygroma fetus, do I've chance for another normal preg? Do I need treatment?

Yes. Any abnormal pregnancies such as this are due to genetic it Tatian's which can happen only one time there's no guarantee you will have another problem like this. To be sure you might want to have genetic counseling or you can check your chromosomes it's possible that you have a chromosome disease that could be inherited most likely it is a random mutation which will never happen again.
