Can cancer cause high hCG levels?
About 10-30% of most cancer patients (like those with lung, breast, or prostate cancer) have elevated levels of hCG. However, hCG tests are most useful for diagnosing ovarian and testicular cancer, which almost always cause high hCG levels [3, 4].
Can an ovarian cyst Raise Your hCG levels?
Conclusion: Mature ovarian cystic teratomas have rarely been reported to secrete HCG. They can be an infrequent source of HCG production and may lead to emergency surgery to treat a suspected extra-uterine pregnancy.
Can cervical cancer cause high hCG levels?
Raised levels of β-hCG have been reported in cervical cancers.
What can cause hCG levels to rise besides pregnancy?
An elevated β-hCG in the absence of viable pregnancy can occur for multiple reasons and has a broad differential diagnosis including miscarriage, ectopic pregnancy, pituitary hCG production, trophoblastic disease and phantom hCG.
How high is hCG ovarian cancer?
These tumors excrete large amounts of hCG (100,000 mIU/mL) and the hormone levels do not decrease as in normal pregnancy but exhibit irregular fluctuations.
Why are my hCG levels so high?
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.
Can ovarian cysts give false positive pregnancy test?
Pregnancy test: A corpus luteum cyst can cause a false positive on a pregnancy test.
Is it possible to have a positive pregnancy test and not be pregnant?

High hCG levels in pregnancy
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. A doctor can use blood tests and scans to check.
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 .
What is a normal hCG level when not pregnant?
Normal hCG levels in nonpregnant women are less than 10.0 mIU/mL. If your hCG levels are outside of the normal range, it could mean a variety of things. Your doctor will help you interpret the results.
