What excatly is a molar preganacy?

Question

What excatly is a morlar pregnancy and how long do you have to get it removed? What happens if you wait too long?

Answer 1

The first answer above is pretty thorough. As for how long before you should have the mole removed, the answer is as soon as possible. The molar tissue grows rapidly and can become a malignant cancer, metastasizing to other areas of your body. Therefore it is best to have it removed immediately by D&C. Afterward, you will have to be monitored with blood or urine samples (depending on where you live; in the U.S. bloodwork is standard, in the U.K. urine is standard) for several months to a year or more to check for regrowth of the mole. You will not be allowed to get pregnant during that monitoring time, because the telltale sign of molar regrowth is a rise in the pregnancy hormone hcg. If you became pregnant, the doctor would not be able to tell for sure whether you were actually pregnant or having another mole.

Answer 2

This happens when your body produces pregnancy hormone but is not pregnant. The body develops placenta but no fetus. There are two kinds of molar pregnancy the first mentioned and the second were a egg is fertilize but is an empty egg...(hormone produced) but no baby. There is a lot of info on the net about it.Check it out.

What is a molar pregnancy?
A molar pregnancy happens when there are certain abnormalities in the fertilized egg at conception. The fertilized egg either never develops into an embryo (this is called a complete mole) or it develops abnormally and can't survive (this is a partial mole).

In normal pregnancies, the fertilized egg contains 23 chromosomes from the father and 23 from the mother. In most complete molar pregnancies, the fertilized egg contributes no maternal chromosomes and the chromosomes from the father's sperm are duplicated, so you end up with two copies of chromosomes from the father and none from the mother. In this case, there's no embryo, amniotic sac, or any normal placental tissue. Instead, the placenta forms a mass of cysts that looks like a cluster of grapes.

In most partial molar pregnancies, the fertilized egg has the normal complement of chromosomes from the mother but double the chromosomes from the father, so there are 69 chromosomes instead of the normal 46. (That can happen when chromosomes from the sperm are duplicated or when two sperm fertilize the same egg.) In this case, there's some normal placental tissue among the cluster-like mass of abnormal tissue. The embryo does begin to develop, so there may be a fetus, or just some fetal tissue, or an amniotic sac. But even if a fetus is present, in most cases it's so abnormal that it can't survive.

It can be scary and sad to lose a pregnancy this way. But as long as you get proper treatment, you're unlikely to have any long-term physical consequences.

How common are molar pregnancies?
About one in every 1,000 pregnancies in the United States is a molar pregnancy. If you're under age 20 or over age 40 or if you've had a previous molar pregnancy or two or more miscarriages, your chances of having a molar pregnancy are higher.

How would I know if I had a molar pregnancy?
Early on, you might have typical pregnancy symptoms, but at some point you'll begin to have some spotting or heavier bleeding. It might be bright red or a brownish discharge, continuous or intermittent, and light or heavy. This bleeding could start as early as six weeks into your pregnancy or as late as 12 weeks. You might also have severe nausea and vomiting, abdominal cramping, and abdominal swelling (your uterus may grow more rapidly than usual).

Some women develop preeclampsia before midpregnancy if they have a molar pregnancy. However, because ultrasound helps practitioners diagnose molar pregnancies earlier these days, it's rare to carry one long enough for this condition to develop.

Call your doctor or midwife right away if you have any spotting or bleeding during your pregnancy. It doesn't necessarily signal a molar pregnancy, but your practitioner will probably order an ultrasound to find out what's causing it and may do a blood test to measure your levels of the hormone hCG. If you do have a molar pregnancy, the ultrasound will show cysts that look like a "cluster of grapes" in your uterus, and your levels of hCG will be higher than normal.

What's the treatment for a molar pregnancy?
If you're diagnosed with a molar pregnancy, you'll need a D&C (dilation and curettage) or suction curettage to remove the abnormal tissue. It can be done under general or regional anesthesia, or you can be sedated intravenously.

To perform a D&C, the doctor inserts a speculum into the vagina, cleans the cervix and vagina with an antiseptic solution, and dilates the cervix with narrow metal rods. She then passes a plastic hollow tube through the cervix and suctions out the tissue from the uterus. Finally, she uses a spoon-shaped instrument called a curette to gently scrape the rest of the tissue from the walls of the uterus.

You'd most likely also have a chest X-ray at this point to see whether abnormal cells from the molar pregnancy have spread to the lungs. It's rare for these cells to spread to other parts of the body, but if they do, the lungs are the most common site.

Your practitioner will then want to monitor your levels of hCG once a week to make sure they're declining — an indication that no molar tissue remains. Once the levels go down to zero for a few weeks in a row, you'll still have to have them checked every month or two for the next year.

One thing to note: If you decide you don't want another pregnancy, you might opt for a hysterectomy instead of a D&C, because it lowers your risk that the abnormal cells will return. Women over 40 who have complete moles are often offered this option because they're at particular risk.

In general, in about 2 percent of women with partial moles and 10 percent of women with complete moles, abnormal cells do remain after the tissue is removed. This is called persistent gestational trophoblastic disease. If it happens to you, you'll need to have chemotherapy with one or more anti-cancer drugs, and you'll have further testing, such as a CAT scan or an MRI, to be sure that the disease hasn't spread beyond the uterus.

With prompt and appropriate treatment, nearly 100 percent of cases of this disease are curable when it hasn't spread beyond the uterus. Even in rare cases in which the abnormal cells have spread to other organs, 80 to 90 percent of cases can be cured. After you're in complete remission, you'll need to have your hCG levels monitored for a year, and possibly other regular testing.

When can I try to get pregnant again?
No matter what kind of treatment you've received, you'll need to wait a year after your hCG levels go back down to zero before trying to get pregnant again. If you got pregnant before then, your hCG levels would rise and it would be impossible for your practitioner to tell whether abnormal tissue was growing back.

The good news is that having a molar pregnancy doesn't affect your fertility or ability to have a normal pregnancy, even if you've had chemotherapy. You're not at any increased risk for stillbirth, birth defects, preterm delivery, or other complications. And your odds of having another molar pregnancy are only 1 to 2 percent. You'll have a first trimester ultrasound in any subsequent pregnancies to make sure all is well.

How can I cope with my sense of fear and loss?
Having a molar pregnancy can be frightening. Like any woman who has miscarried, you're dealing with the loss of your pregnancy, but in this case, you've had an unusual condition that most people have never heard of and you're concerned for your own health as well. You have to undergo a minimum of a year of weekly or monthly follow-up visits before you can try to conceive again, and you may be very anxious about the possibility of having persistent abnormal cells. If you do have persistent disease, treatment with chemotherapy can be very draining and can delay your next pregnancy even longer.

You may feel devastated by your experience. Your partner may also be feeling sad or helpless and may have trouble figuring out how to express those feelings or how to be supportive. It's perfectly okay to seek counseling if you think it will help you or your partner cope. Ask your caregiver where to get counseling or find support groups.
