Ca-125 (cancer antigen 125 or carbohydrate antigen 125) is a biomarker/tumor marker for ovarian cancer (etc); however, it is not sensitive or specific enough to use as a screening test. Also, a uk study showed that treating based on ca125 level did not improve outcomes. "125" comes from the 125th attempt to develop a marker. It was introduced by bast ...Read more
If ca19-9 within normal levels or negative, are you cancer free? Is there a test to show that you are in the % group that can't produce the antigen?
Misconception: Only a handful of cancers produce ca19-9, and even then it's won't be detectable at a significant level unless there's enough mass of the cancer to produce it. This is not a screening test. If levels drop to undetectable after surgery, it's no guarantee of a cure. It's most useful to follow and watch for recurrences of a known ca19-9 producing cancer. ...Read more

What does it mean when the CA19-9 level goes back to the normal range when someone has pancreatic cancer? Is this a sign of remission?
Well....: If it was elevated before surgery and now is normal, I would say it is a very good thing BUT, that as of itself does not mean it is in remission or that it will stay that way. Cancer can exist in microscopic form and often there is no way to know for sure, be it with labs or even with scans. Such patient will need long term follow up and maybe even consider post operative therapy. Best 2U! ...Read moreSee 1 more doctor answer
Yes and No: Ca-125 is a test for follow-up after diagnosis and with the treatment of ovarian cancer. It is elevated in many other diseases.The test should not be used for a fishing expedition because it would be misleading and concerning for a patient like you. Why was the test done in the first place? Do you have cancer? In any case a 25 level could be normal? What was the normal range.In the lab? ...Read more
Ca 125: The "normal" ca125 was established for post-menopausal women at <35 (any value 0-35). Most premenopausal women will also have values in this range but not always since there are many benign reasons it can fluctuate. Some "healthy" women of all ages will have a level above 35! this is one of the reasons it is not effective as a screening test. ...Read moreSee 1 more doctor answer
