What type of cancer produces hCG?

What cancers cause high hCG?

Takeaway. Ovarian and testicular cancer can dramatically increase hCG levels. Other cancer types, such as breast and lung cancer, may also increase hCG blood levels.

What kind of tumors produce hCG?

Levels may be elevated to similar levels as seen in testicular cancer. Among nonreproductive tumors, hepatobiliary tumors (hepatoblastomas, hepatocellular carcinomas, and cholangiocarcinomas) and neuroendocrine tumors (eg, islet cell tumors and carcinoids) are those most commonly associated with hCG production.

What causes high hCG levels and not pregnant?

Although the most common cause of an elevated HCG level in females is pregnancy, occasionally, a HCG-secreting tumor is suspected and other conditions such as gestational trophoblastic disease (GTD), nontrophoblastic neoplasms, or a pituitary source of HCG, must be considered.

What type of tumor is most likely to produce hCG and AFP?

Embryonal carcinoma can secrete HCG or alpha fetoprotein (AFP). Yolk sac carcinoma: the most common type of tumor in children; responds well to chemotherapy in children and adults. Yolk sac tumors almost always secrete AFP.

Can a tumor cause hCG?

Human chorionic gonadotropin (hCG) is a hormone, made up of an alpha and beta subunit, that is produced by the placenta and normally is only measurable during pregnancy. Some abnormal tissues, tumors, and cancers, however, may also produce hCG, making the hCG test useful as a tumor marker.

How common is an hCG secreting tumor?

Elevated in all cases of gestational trophoblastic disease, hCG serves as an ideal marker, contributing to diagnosis, treatment monitoring, and follow-up. hCG-secreting germ cell tumours account for 40–50% of non-seminomas and 15–20% of seminomas tumours [1].

What causes hCG to rise?

Causes may include a placental tumor or molar pregnancy, in which a non-viable egg implants in the uterus and secretes the hCG hormone. Higher levels of hCG may also represent pregnancy with multiples, or an inaccurate measurement of gestational age (the pregnancy could be further along than expected).

What does it mean if your hCG levels are high?

High values

If you are pregnant, very high levels of hCG can mean a multiple pregnancy (such as twins or triplets). It can also mean a molar pregnancy or Down syndrome. You may also be further along in an early pregnancy than you thought, based on your last menstrual period.

What causes phantom hCG?

The reason for a phantom hCG is that some individuals react falsely positive to some substrate in the blood hCG test and thus will display a consistently low positive blood pregnancy test even though they are not pregnant, but their urine test will be negative.

Can fibroids cause high hCG levels?

Uterine fibroid is benign non-cancerous growth which tends to multiply very rapidly during increased HCG levels. This phenomenon mostly occurs during pregnancy and that too especially during the early stages of pregnancy.

Are High hCG levels bad?

As with low levels, high levels of hCG do not necessarily indicate a problem with a pregnancy. Some women simply have higher levels. If a woman has high hCG levels, it could point to twins or triplets, though only a scan can confirm this. Sometimes, above-average levels of hCG indicate a higher chance of Down syndrome.

What are the symptoms of high hCG levels?

A few days after implantation, hCG levels may be high enough to cause early pregnancy symptoms.

Some other symptoms of early pregnancy include:

  • darkening in the color of the nipples.
  • fatigue.
  • food cravings or increased hunger.
  • increased need to use the bathroom.
  • gastrointestinal changes, such as cramping or diarrhea.
